Dark Fiber Testing and Debugging Process

2012-11-12T19:55:16Z

Henry.joshua:

Dark Fiber is where ACD provides physical fiber cable connectivity between two or more sites, without providing the electronics necessary to light the cable. ACD generally does not operate or maintain the equipment for the customer, although ACD usually is needed to assist the customer to determine if the connection issue is actually a fiber issue (ACD's responsiblity), or customer equipment (Customers responsibility). ACD should be proactive in facilitating resolution and testing. ACD has the necessary equipment to effectively test fiber strands, and usually customers do not due to the expense of the equipment.

==Point of Demarcation and Responsibility==

ACD's network elements:

# Fiber Cable that is outside of the building, conduit, pole attachments and entrance facilities into the building.
## In some instances where ACD is utilitizing the customer provided entrance facilities (i.e. conduit that on the customer grounds, or inside the customers building) the customer has provided us with entrance facilities, and is having ACD use them.
# Fiber Cable coming into the building; and is prior to the fiber termination box.
# The fiber termination box, and the connectors directly attached to the fiber termination box.

Customer's network elements:
# Patch cables from the fiber termination box to their equipment.
# Network Switches/Routers
# Optics; typically these are pluggable modules, such as GBICs, SFPs, Xenpaks and other industry names for optical Modules.

== Problem Reporting by Customer ==

When the customer contacts ACD we need to quickly determine the issue the customer is reporting.

# '''Complete Outage:''' Where there is no connectivity between sites.
## Is the outage affecting all fibers between a site or only specific fibers?
## ACD needs to know which fibers are having the issues.
# '''Transmission Errors:''' Transmission occurring, but CRC errors on customers interfaces are accumulating
## Is this occurring on all fibers between a site or only specific fibers?
## Are the errors on both on the TX and RX sides of the interfaces on both sides?
# '''Intermittent Outage:''' Transmission is occurring, but is stopping occassionally.
## What time of day?
## Any pattern to the intermittency?
# '''Low Light Level:''' The light emitted from the customer's laser is low on the RX end?
## What is the DB attenuation of the fiber strand that is having a problem?
## What is the loss ratio from the Launch Laser to the Terminating location?
## Is the low light level occurring on all fiber strands?

'''Additional Questions'''

The more information we have the quicker we can isolate the issue and get the connection up and running. These other question that help ACD reduce the time of its own debugging process are:

# Did the problem report start when the Customer was performing any maintenance?
# Did the problem report start when ACD was performing any maintenance that the customer is aware of (i.e. during a posted maintenance window relevant to the customers services)?
# What testing has the customer done on their equipment?
# What testing has the customer done on the fiber strands provided by ACD?
## Has the customer put a light meter on the RX end of the strand that is having a problem?
## Has the customer run an OTDR test?
## Has the customer swapped any equipment?

==Possible Reasons for Customer Reported Problems==

ACD is committed to resolving all customer issues, and assisting to resolve issues that are not related to ACD caused issues. We want the customer's connections with ACD to be resolved promptly. ACD will deploy personnel proactively to examine customer equipment and connections to isolate where the error is, even if we initially suspect that the issue may not be on ACD's provided dark fiber.

Often times it takes both parties to correctly isolate where the problem is, particularly on issues that are on the customers equipment. Usually the customer does not have the equipment in inventory to do dark fiber testing. Therefore, it is necessary that ACD be proactive in deploying employees with test sets that can determine if there is an issue on ACD fiber or Customer Equipment.

# '''Customer Reported Complete Outage''': A complete outage is where there is no transmission between the sites, and is the most common sort of outage.
## '''Outage that is due to problems with ACD's network elements:'''
### Storm/Weather damage to the cable
### Tree Trimming damage to our cable. Pole owners do not typically notify us of tree trimming activity.
### Utility or Contractor damage to the cable.
#### Sometimes other utility contractors accidentally damage our cable when performing work on another cable or doing underground work. ACD typically does not know about this work beforehand.
### ACD caused a outage during a splicing. ACD mis-spliced the fibers on a cable.
#### An ACD maintenance notice should have been posted on the same cable the customer is using.
#### ACD employee mis-identified the fiber strands on the cable, and that is the cause of the error.
### Outage at the fiber panel.
#### Usually due to too much pulling of fiber jumper cables on the fiber panel, or mishandling by ACD or Customer. Reseating or replacing jumpers often will fix this problem.
#### Some fiber panels are used to service multiple customers, and ACD or the end-user customer has inappropriately moved or damaged jumpers.
#### ACD will typically not have a maintenance notice posted on customer facing access to the fiber panel.
##'''Outage that is due to problems with Customer's network elements''' ACD is responsible for proactively participating and resolving the issue to make sure the customer is back up and running as soon as possible.
### Router/Switch/SONET Equipment Issue.
#### Confirm with the customer that
### Equipment failed or not powered on.
### GBIC/SFP/Xenpak is defective.
#### We find that this the most common reason for outage. Lasers generally degrade (signal weakens) over time an this should be one of the first items to be looked at. Lasers tend to be high failure rate objects.
#### ACD often does not have the same inventory of GBIC/SFP/Xenpak as the customer uses, however if we do, provide them to the customer, for eventually replacement of billing to get them back up and running. Many of the products are unique, and therefore swapping out lasers on both ends will often be necessary.
### Mis-configuration of equipment.
#### Usually a maintenance notice will be posted by the customer.
### Jumper cables damaged.
#'''Customer Reported Transmission Errors'''
##'''Outage that is due to problems with ACD Network Elements''' = Include all issues on '''Customer Reported Complete Outage'''
##'''Outage that is due to problems with Customer's network elements''' ACD is responsible for proactively participating and resolving the issue to make sure the customer is back up and running as soon as possible.
###Transmission errors are usually found to be on customer equipment.
####If light levels are low on the transmitting customer lasers, the errors can be on ACD's fiber if the transmitting lasers are at the edge or margin of the distance that they are supposed to be able to go.
####Generally ACD recommends that the customer upgrade fiber optic lasers to stronger levels if they are near the margin of DB loss of recievers.
###Jumpers not being placed fully within the jacks is a common reason why we see transmission errors.
####This often occurs when jumpers are yanked or pulled excessively and are pulled or stretched from the Fiber panel.
####Fiber Panel SC-SC or LC-LC modules have occasionally been at fault
#'''Customer Reported Intermittent Outage'''
##'''Outage that is due to problems with ACD Network Elements''' = Include all issues on '''Customer Reported Complete Outage''' & '''Customer Reported Transmission Errors'''
###Cable is streached somewhere, possibly in the splice case, possibly at the fiber panel.
###Need to determine if the issue is weather related.
##'''Outage that is due to problems with Customer Network Elements''' = Include all issues on '''Customer Reported Complete Outage''' & '''Customer Reported Transmission Errors'''
#'''Customer Reported Low Light Levels:'''
##'''Outage that is due to problems with ACD Network Elements''' = Include all previous sections.
###Special care is needed to determine the source customer laser strength (on bothend), and calculate the DB loss of the link based upon the source strength of the connection, compared to the outside plant readings.
###Special care should reviewed on the fiber panel modules, and inside the fiber panel to ensure that the fiber strands are loose and not streached.
##'''Outage that is due to problems with Customer Network Elements''' = Include all previous sections.
###Pay special attention to the strength of any attenuators that the customer has placed on the network.
###Pay special attention to the comparative strength of pair of lasers that are used on the network. Often laser strength degrades over time on GBIC/SFP/Xenpak and other optics, and the degradation may be at different rates, and one end of the link may not have enough laser stregth to push through the natural loss on the cable.

==Impact of ACD testing==

In order to test dark fiber strands that are having issues, the customer equipment needs to be disconnected. There is no way to test fibers without disconnecting equipment, therefore any request should be with the understanding that it will be service affecting, at least on the fiber strands that the customer requests testing.

If there are spare adjacent fibers that are on the same cable, we can test these for continuity of the overall fiber cable. If continuity is good on the spare fibers, this can mean that the overall cable is not fully cut. If the spare strands are functional, equipment can be reloacted to the spare cable.

The customer should advise ACD:

# '''Invasive Testing:''' That they authorize or not authorize ACD to perform immediate intrusive testing.
## The fibers they authorize testing on means an existing connection will be down during the testing, if it is not already down.
## ACD can test adjacent spare fiber to determine overall cable integrity, the customer should advise if they authorize intrusive testing on ''spare'' fibers.
# '''Maintenance Window Testing:''' Customer may request that ACD can perform testing during a maintenance window.
## ACD's ability to initiate repairs will not start in most circumstances until testing with an OTDR can be performed.

==Equipment and Documentation Required for Testing==

# '''Light Meter:''' A light meter is a devices that is able to read the light strength from the emitting laser. The light meter tells whether the laser light being emitted is strong or weak, and within the range of the light sensor to read the light. As light travels down a fiber cable, the strength of light is slowly degraded.
## ACD typically sets the light meter to 1550 wavelengths, however the meter should always be set to the wavelegth of the transmitting laser. Usually this is 1310 or 1550 for most equipment nowadays.
# '''OTDR Meter:''' A Optical Time Domain Reflectometer (OTDR) is an expensive device that sends a series of signals down a fiber strand to determine a number of aspects about the fiber cable. A OTDR device can tell where a) A bad splice exists b) Potentially where there is damage that is decreasing the strength of the light signal, c) determine the length of the fiber strand. This is most relevant if the length is less than the actual length of a cable, this means that there is a break in the cable somewhere.
## ACD sets OTDR testing equipment to 1550 nanometers wavelengths. Variation in the the wavelength selection will substantially adjust the data results.
# '''OTDR Documentation: ''' OTDR documentation are the documents that are created at the time of delivery of the fiber service to the customer. This documentation lists the characteristics of each individual fiber strand, just after it was built. By comparing the historical OTDR readings to the current OTDR reading it can be determined if there is now a difference in the cable. Only by knowing the difference between OTDR documentation at the time of delivery and current OTDR test results, will the problem likely be isolated.
# '''As-Built Drawings:''' As built drawings are documents that describe the construction performed by ACD. These drawings detail the overall route of the cable, including poles that the cable is attached to, handholes, splice cases, fiber termination panels, and whether the fiber is above ground or below ground.

==Step by Step Troubleshooting Process==

#'''Troubleshooting process'''
##If the customer allows invasive testing:
###Go to ''SITE A'', place a light meter on the live RX fiber (the fiber with the light), record the reading, the reading should be between -4DB margin and -22DB. While driving to the sites, if possible, the As-built route should be driven to check for any obvious outside plant damage.
####If outside this range may signify that the light is either too hot or too cold for the sensor on the customers equipment.
#####Equipment can operate outside of this range, so if it is outside this range, it does not mean that it is the primary issue, just that this is something to review and potentially adjust.
####In general it is best to have the DB RX range be between -8 to -16 or so.
###At ''SITE A'', The light meter should be placed on the the live TX fiber (from the customers local equipment). The reading here should confirm that the customer's laser at ''SITE A'' is sending light.
###The light strength should be adequate to transmit the light minus the expected DB loss of the fiber at the customer's site.
###At ''SITE A'', Place OTDR meter on the fiber panel and shoot all fibers to the customer ''SITE B''.
####Record all information, and compare it to the base line documentation we have when the fiber was constructed.
####All data should be the same, if there is substantial variation, then the fiber cable is at fault.
#####If there are spare strands, and the existing OTDR readings are fine on the spare strands, but not fine on the existing operational strands, relocate the customer to spare strands temporarily to get them operational. Both ends will need to be visited to ensure to relocate the customer.
###If no issues are found on the light meter or the OTDR, proceed to ''SITE B'', and perform the same testing performed aT ''SITE A''
####While en-route between sites, if possible it would be preferable that the route taken to drive is the same route as As-builts to check for any obvious outside plant damage.
####Light meter testing should be performed on the RX fiber and the TX fibers.
####The RX level at ''SITE B'' should equal the output of the laser at ''SITE A'' '''minus''' the DB loss on the OTDR report. If you go back to ''SITE A'' the same data should be the same or similar, and within -2 to -22 db range, and preferably within the -6 to -16 range with the loss of fibers.
#####Pay special attention to any attennuators that may be on the customers equipment, as the attenuators substantially adjust the strength of the light. attenuators are occassionaly the root issue, particularily if there is issue with CRC errors
###If no issues are found on the fiber cable, all the same testing should be performed ''with and through the customer's patch cords and attenuators''. Testing should be performed with the light meter and the OTDR to detect any issues related to loss that could occur through the fiber patch cords, attennuators and/or the fiber panels.
##If the customer does not allow invasive testing:
###If there are spare fibers, then we can still go to the site and test on the spare, unconnected fiber ports. OTDR readings should be taken at both ''SITE A'' and ''SITE B'' and compared to the base line construction OTDR readings.
####If the results show clean OTDR shots, the outage is either due to the individual strands that we provide are bad (i.e. the particular strands that the customer is live on), or it is the customers equipment, patch cords or fiber panels. If possible test from the customer fiber panel (if it exists). If the OTDR results are not clean, then there is likely damage to the overall fiber cable, and Outside Plant Repairs should be started.
####If the results show clean at both sites, the route should be driven, inspecting for any obvious damage.

ACD is aware that some of our customers may have received an email that appears to be from us asking for personal information. Often, these emails state that we are upgrading a system or that we are compromised by a virus and need you to respond with your password. This is a deliberate attempt to compromise your email account so that a malicious person can use it for spam, or additional "Phishing" attempts.

ACD.net will '''never''' ask for personal information, like passwords, '''via email.''' Please do not respond to these emails.

If you have responded to any email asking for your personal information, please give us a call at 517.999.9999 so that we may change your password. This will help prevent your account from being compromised.

Following is a write up regarding Phishing Emails:

"Phishing" or spoofed email, is an increasing problem for our email users. These types of messages look like they come from a legitimate source asking for personal or account information. You should never respond to or click on any links in any email asking for personal information.

Email scams are becoming more sophisticated and widespread every day. One common scam, the phishing email, directs consumers to spoof Web sites that look like the real thing. Their goal is always the same-to get your financial information.

Follow these tips to recognize phishing emails and keep your identity safe and secure:

*Phishing emails usually have an urgent tone, threatening discontinued service or financial loss if you don't take immediate action.
*Even if they look like the real thing, many scam emails have misspellings, bad grammar or poor punctuation.
*Fake emails often use generic salutations such as "Dear account holder" instead of being personalized with your name and account information.
*Check to see if the sender's email address is from the company represented in the email. Phishing emails are usually sent from an outside or foreign email address.
*Check the Web site link they want you to click on. By moving your mouse over the link, you may be able to see where they want to take you, and whether the address is a valid page on the company's Web site.
*If you are in doubt, type the link address directly into your Web browser. Never click on the link contained in the email because it could harm your computer.

Remember, ACD will '''never''' ask you to provide personal identifying information through an email. Even if the message looks legitimate, always call us directly rather than providing any information online.

For more information about phishing, please visit http://onguardonline.gov/phishing.html.

If you have responded to or suspect you have entered your ACD.net information on a "Phishing" website, please give us a call to change your password.

Email Scams and Phishing Attacks

2012-09-14T15:39:53Z

Henry.joshua:

=Is this email really from ACD?=
ACD is aware that some of our customers may have received an email that appears to be from us asking for personal information. Often, these emails state that we are upgrading a system or that we are compromised by a virus and need you to respond with your password. This is a deliberate attempt to compromise your email account so that a malicious person can use it for spam, or additional "Phishing" attempts.

ACD.net will '''never''' ask for personal information, like passwords, '''via email.''' Please do not respond to these emails.

If you have responded to any email asking for your personal information, please give us a call at 517.999.9999 so that we may change your password. This will help prevent your account from being compromised.

Following is a write up regarding Phishing Emails:

"Phishing" or spoofed email, is an increasing problem for our email users. These types of messages look like they come from a legitimate source asking for personal or account information. You should never respond to or click on any links in any email asking for personal information.

Email scams are becoming more sophisticated and widespread every day. One common scam, the phishing email, directs consumers to spoof Web sites that look like the real thing. Their goal is always the same-to get your financial information.

Follow these tips to recognize phishing emails and keep your identity safe and secure:

*Phishing emails usually have an urgent tone, threatening discontinued service or financial loss if you don't take immediate action.
*Even if they look like the real thing, many scam emails have misspellings, bad grammar or poor punctuation.
*Fake emails often use generic salutations such as "Dear account holder" instead of being personalized with your name and account information.
*Check to see if the sender's email address is from the company represented in the email. Phishing emails are usually sent from an outside or foreign email address.
*Check the Web site link they want you to click on. By moving your mouse over the link, you may be able to see where they want to take you, and whether the address is a valid page on the company's Web site.
*If you are in doubt, type the link address directly into your Web browser. Never click on the link contained in the email because it could harm your computer.

Remember, ACD will '''never''' ask you to provide personal identifying information through an email. Even if the message looks legitimate, always call us directly rather than providing any information online.

For more information about phishing, please visit http://onguardonline.gov/phishing.html.

If you have responded to or suspect you have entered your ACD.net information on a "Phishing" website, please give us a call to change your password.

Bandwidth or Speed Testing

2012-08-05T10:23:39Z

Henry.joshua:

For some basic information about speed testing click here: http://www.acd.net/speedtest.cfm.

'''"Speed Testing"''' is a common thing end-users do to see what kind of connection they have on the Internet. However, Speed Tests that are hosted on the public Internet are not always of high quality. This is because the speed test often does not have accurate servers or systems, and also the number of hops from your computer to the speed test server can dramatically affect the results.

There are several ways to "Test" your speed, with varying accuracy and quality.

*[[Iperf Speed Testing]]. This is a highly reliable way to do an accurate speed test, however, it requires some configuration and knowledge. If you want to do speed debugging, then please click on the link. All performance testing done by our [http://www.acd.net/noc.cfm Network Operation Center] is performed using this testing. This is the same speed testing ACD uses internally, and is the general debugging mechanism used by ACD to debug all connection bandwidth issues.

*http://www.speedtest.net and [http://speedtest.acd.net http://speedtest.acd.net]. This is a browser based interface. No browser based interface is going to be highly accurate, especially at high speeds, including these common consumer speed tests. However, it provides results quickly. The advantage with browser based speed tests is that they work through firewalls. However, they do not work accurately, primarily because they a) utilize only one udp stream b) and the tests operate for only a very short period of time. These speed tests are not accurate for:
**any bonded types of connections, or link sharing technology.
**[http://www.acd.net/t1.cfm Bonded T1 lines]
**[http://www.acd.net/adsl2.cfm Bonded ADSL2+]
**G.shdsl.bis or [http://www.acd.net/efm.cfm Ethernet First Mile]

How to Flush your DNS Cache on your computer

2012-08-05T10:19:20Z

Henry.joshua:

Flushing your DNS cache is a way to troubleshoot DNS lookup issues and web page resolving issues from your computer.

The reason to flush DNS Cache is to ensure that your cache has the latest correct data. It is important to do this when there are server changes, moves or updates, or you are relocating your hosting or email to a new server, ip address or a new server hosting company.

Typically, DNS Cache is something that is handled between your PC and the DNS server it is attached to. However, devices such as firewalls may also cache DNS entries on behalf of your PC. These devices may need to be flushed as well.

==How to Flush your DNS cache on Windows PC==

*Get to the command prompt. You can do this by click on on >Start>Run and typing "CMD" and pressing return. This should open a black window.
*Within the window, type ipconfig /flushdns and press return.
*Ping the website or hostname you are having an issue with. The ping will return the ip address that is associated with the DNS name.

==How to speed up lookup performance==

*Usually, the reason people have to flush their DNS is because the TTL (Time to Live) is set too high on their firewall or on the DNS server that they are pointed to. Back in the old days of the Internet there were not a lot of DNS changes, so the DNS default is set to 3 days. Often, equipment is set to use this as a default because this is the Internet standard. Nowadays this is too long because server administrators are moving around and updating servers on a regular basis.
*To improve performance, you can lower the TTL on these systems. Setting your DNS cache to 4-8 hours is a reasonable amount of time.

Demarc Extension Wiring Specifications

2012-08-05T10:14:20Z

Henry.joshua:

Demarc Extensions, which extend the wiring from the [[Network Interface]] to the inside of a building or through a building to where your equipment sits, are a critical portion of the network. Often, the speeds or stability that a customer can get from ACD is significantly affected by the quality of the inside wiring.

The wiring that ACD recommends is the following, based upon information gathered on testing and debugging and the written specifications from vendors. Changing out your internal wiring may not make a difference, if the wiring you have is of good quality. However, if the wiring is of low quality, then changing out your wiring will make a substantial difference.

==Recommendations for DSL or EFM Service Wiring==

*''Use Solid Core Wire''', do not use stranded wire. Stranded wire is what is in cheap phone lines.
*'''For DSL or EFM copper loops''' use Cat 5, Cat5E, or Cat 6 wiring from your network interface to your Modem Jack. Basically, the larger the gauge of wire, the better your connection is likely to be. Short lengths of this type of cable can be bought at most home improvement stores.
*'''Keystone type jacks are the best'''. These can be purchased at Home Depot, Menards or Lowes in the Electric department. Leviton is the common brand. For cheaper prices you can order this stuff from the web. These stores are usually expensive.
*'''For Regular DSL''' Cat 3 RJ-11 Keystone Jacks work fine.
*'''Ground your power outlets'''. The power outlets that you have should be grounded in your house, this decreases electromagnetic interference on all wiring in your house.
*'''Shielded Wiring''': For best results, use shielded wire, and ground one end of the shield on a ground.
*'''Avoid Running Data Lines near Power Lines'''. Avoiding perpendicular wiring crossing major power lines may significantly improve reliability. For example, high voltage equipment can cause magnetic interference on your DSL, Phone, EFM or T1 lines. Common devices that turn on and off and are likely to cause interference are Copiers, Air Conditioning Systems, Furnaces, and Main feed lines into buildings. The goal is to avoid electromagnetic interference. Usually, running data lines in parallel to these power lines or curving them into these lines when needed, is better than doing a straight perpendicular crossing.
*'''Do not plug your data lines into Surge Suppressors where not needed'''. Although surge suppressors can save your modem, they can also cause interference on your line.
*'''Minimize the number of "Splits" on your data or voice line'''. If you split your home phone line or DSL a number of times to connect to various outlets, it is best to minimize the number of splits, and to make sure that where these splits occur the wiring is of high quality at each junction point. Each split creates an "antenna", collecting magnetic interference.

==Recommendations for T1 Wire==
*'''T1 Wire''', which is a unique type of wire, should be used for any demarcation extensions past 25 feet from the [[Network Interface]]. T1 wire is a specific type of wire made for just T1 lines. It uses RJ-48 Jacks, which are different than the types of jacks used for Ethernet(ethernet uses RJ-45 Jacks).
*'''Using Ethernet Wire for T1 Wiring extensions:''' Although generally acceptable, you should never use "stranded" wire, you should use "solid core" wire, and never more than 25 feet from the Network Interface.

Truck Roll Fee

2012-08-05T10:06:15Z

Henry.joshua:

Truck Roll Fee or TRF for short, is a fee that ACD charges to the customer for performing troubleshooting and debugging.

Truck Roll Fees will be charged in the event that a customer requests a dispatch to their site, and the problem is not found to be on ACD provided equipment or ACD provide networking, or the customer refuses to allow ACD to perform testing at the site to debug or resolve the issue.

It is policy to inform customers prior to dispatch that they may have to pay the truck roll fee if the issue is not on ACD's side of the network.

==When we assess the Truck Roll Fee==

We assess the truck roll fee after we go to the site and the technician returns with the notes from the site visit. We also take into account the prior troubleshooting notes.

==Why we assess a Truck Roll Fee==

Sending out field people is very expensive. We want your connectivity to be cost efficient. One of the ways to accomplish this is ahaving truck roll fees, which usually occur when adequate troubleshooting is refused by the customer. We need to make sure that the issue is not with our network. If it is with your network, then while we will provide limited free telephone support service, the cost of sending out people to assist with service on portions of the network that are not ours is an expense that is not related to our network.

==Refusal or Impediment to ACD performing troubleshooting==

ACD is required to perform a series of tests to collect data, in order to facilitate resolving technical issues. If the ACD customer refuses ACD's requested testing, ACD will be unable to accurately assess and debug technical issues. In general, ACD can and will perform any intrusive testing at a time that most minimally impacts customer operations.

In a situation where a customer refuses to allow ACD to perform its troubleshooting, a Truck Roll Fee will be assessed for the service call and any other service calls that ACD is restricted from performing troubleshooting.

Service Cancellation Policy and Request

2012-08-05T09:58:39Z

Henry.joshua:

ACD provides communication services, which are critical to home and business operations. Often times our service includes the provision of 911 service. Customers also use our communication services for secure services such as monitoring, network management and security services.

In order to ensure that service is not terminated inappropriately, ACD requires service to be cancelled in confirmed writing via the following requirements.

==ACD does accept cancellation in the following manner==

*Login to [http://myaccount.acd.net myaccount.acd.net] The best way to do this is to put in a service cancellation service ticket within http://myaccount.acd.net. The date of the service cancellation is then logged, and the ip address is logged.
*Via Certified Letter
*Via a received fax from your location. Upon receipt of your fax, we will open a service ticket associated with your account. If you do not see a service ticket is opened on your account within 24 hours, we did not receive your fax.

==ACD does not accept cancellation in the following manner==

* Verbal communication in any way to ACD. For example, we do not accept service cancellation by a verbal telephone contact to a salesperson, customer support person, or via a call to our accounting department. We cannot for certain verify that the person on the phone is an actual person.
* Via Email. Email does not have a tracking mechanism so that you are certain that your email sent was received by ACD. Email addresses can also easily be spoofed. We do not, under any circumstances, accept cancellation verbally, whether confirmed or not.

==Timing of Cancellation==
* ACD will not retroactively back date cancellations and stop charging fees, if the customer does not appropriately cancel according to the requirement.
* ACD will not be responsible for charges, moves or changes without a 30 prior notice of cancellation.
* Porting your phone numbers to a new provider does not constitute cancellation of service.

==Suspension of Service==
* ACD does not allow temporary suspension of Broadband Internet or Phone service at the request of the customer. Some customers request this if they are going to be gone for a couple of months or on vacation. Unfortunately, ACD has to continue to pay for lines and maintain lines regardless of whether you are actively using them or not. Therefore, ACD has no provisions to allow temporary suspension of service. If you are going to be gone for a long time, you may wish to cancel service and restart service at a later date. However, there may be additional fees for restarting your service.

==Cancellation or Suspension for Non-Payment==
* When customers have failed to pay their bill, and ACD has made multiple requests to get payment, and the customer does not respond, ACD can and will temporarily disable service. If we do not get the payment resolved, ACD will cancel the Phone, DSL or T1 line and remove the circuit in operation. In the event ACD removes the circuit from operation, and the customer wants service back, the customer will have to pay any back fees and fees associated with a new installation. In this case, a new installation window will occur.

==Cancellation Forms==

Porting Guidelines and Specifications

2012-08-05T09:53:01Z

Henry.joshua:

ACD does porting from all other phone companies, cable companies and cell phone companies.

When porting number in, we generally will perform ports Monday Through Friday, but we can schedule ports over the weekend, in special situations with certain providers.

Providers that we commonly port from.
# AT&T
# Frontier
# Comcast

Information we need to port in:
* Phone Number
* Who the existing provider is.

Order Processing Delay or Suspension

2012-08-05T09:51:15Z

Henry.joshua:

This document explains ACD's policy related to Order Processing Delay or Suspension.

ACD may delay or suspend order processing for the following reasons:

*Non-payment or untimely payment of ACD's Invoices.
*The underlying end-user customer has other unpaid bills or unresolved disputes with ACD, regardless of whether the order has been processed by an existing or new agent for the end-user customer.
*The order does not have the complete documentation associated with the order.

In these scenarios, ACD service processing delays, due the below reasons, are not covered by ACD's time commitment to complete orders.

==Non-Payment or Untimely Payment==
The term of payment is 20 days on our bills. While we understand that unique circumstances may exist for customer occasionally, ACD's business is to provide telecommunications services, not to provide financing activities for customers. Therefore, we need timely payment on bills.

*'''Unpaid bills in the 30-60 day column:''' If the customer has bills that are unpaid in the 30-60 day column, ACD management, at its discretion, may suspend pending, in process, or new orders, if the issue of timely payment is chronic.
*'''Unpaid bills in the 60-90 day column or greater:''' All pending, in process, or new orders will not be processed. Exceptions may be made only by senior management (Kevin Schoen, CEO, Steve Schoen, President & COO, Kirk Shewchuck, CFO).
*'''Unpaid in the 90+ day column:''' All pending or new orders are halted and all services are subject to immediate suspension.

==Underlying End-User Unpaid Bills==
ACD provides services on a retail and a wholesale basis. Occasionally, an end-user will game between service providers to avoid bills. This usually occurs in these scenarios:
* An ACD retail customer will switch to an ACD wholesaler to avoid payment of their bill.
* A wholesale customer will switch between two different ACD wholesalers, or agents, to avoid payment of a bill.
* In some situations a wholesale customer will switch to ACD directly in order to avoid payment.

In general, it is ACD's policy to ensure that the end-user does not inappropriately avoid payment of services that are provided by ACD. ACD will exercise reasonable discretion to address these matters.

==Incomplete Orders==
Incomplete orders will generally not be processed. Errors in orders will need to be fixed prior to orders being processed. Orders should be sent to orders@acd.net

Customer Requested Credits

2012-08-05T09:45:34Z

Henry.joshua:

ACD does provide credits for service outages that are requested by customers. The guidelines that apply for service credits are contained in this document.

A request must be made on http://myaccount.acd.net. Create a service ticket to the Accounting Department as to the reasons for the service credit. ACD will reply with the status of the credit request.

==Circumstances where ACD does not provide service credits==
*ACD does not provide a service credit for greater than the length of outage.
*ACD will not provide any credit for consequential or incidental damages, lost data, or lost revenue due to service being out. The credit will never exceed the amount of service charge that ACD provides to the end-user.
*ACD does not provide service credits for delay of installation of new services. Many factors related to installation delays are out of our control. Therefore, and additionally, ACD does not provide credits for services that we are net yet billing for.
*ACD does not provide service credits due to service outages that occur during [[Posted Maintenance and Maintenance Windows]].
*ACD does not provide service credits due to failure of customer owned equipment, even if ACD was involved in troubleshooting that equipment with the customer.

Emergency Stocking Inventory of Equipment

2012-08-05T09:41:27Z

Henry.joshua:

ACD maintains many network spares in house. We run a large network, therefore we have to have a lot of stock of gear. What does this mean for you? You know we will have equipment on hand to repair our network when something breaks. We usually do not have to wait for a vendor to get a component to fix our own network. In a worst case scenario, ACD will loan equipment to existing corporate customers, (as long as we have adequate in inventory) for short periods of time, in the event the customer has a significant outage. We are not required to do so, and this is not a service commitment. The loans are only for short periods of time, and ACD may charge a fee for this. If the equipment is not returned soon, we will bill you for the equipment loan.

The equipment we use is specific to our needs. When evaluating which platforms to deploy on our network, the principles below guide our decision making:

*In high volume production deployment.
*It is tried and true and has a high reliability rate.
*Is considered a '''Mainline''' piece of hardware.
*Does not have a lot of unnecessary bells and whistles. The more complicated the software, the less reliable it is. We need software that has been through a lot of cycles, and is tried and true.
*We at times do not acquire the "latest generation" of hardware. From a reliability and code quality standpoint, this is usually risky. Since we all depend on a highly reliable network, we have found that the later generations of hardware, which are often low production and also have further refinements that need to be made at the board and chip level, have initial quality or reliability issues.
*We and Cisco have extensive debugging experience on the platform that we are going to use.
*Support specific needs ACD has, such as MPLS and other service provider feature sets. Not all hardware sold to enterprises support the specific functions we need.
*ACD limits the amount and type of equipment for debugging and stocking purposes.
*Possess the lowest overall cost of operation.

Cisco Routing and Switching Equipment we have in inventory that may be available for temporary use for customers:

*Cisco ONS-15454 Sonet Platforms
*Cisco 124XX Switch Routers
*Cisco 7507 Routers
*Cisco 6509 Core Switch/Routers
*Cisco 7206 VXR Aggregation Routers
*Cisco 3550 Switches of various types.
*Cisco 55XX Switches - Old inventory not in production use.
*Cisco 3662 Telco DCN Routers
*Cisco 28XX Routers
*Cisco 26XX Routers
*Cisco 18XX Routers
*Cisco 17XX Routers

#Outgoing Server: This is normally smtp.acd.net on port 25.
#Outgoing server needs to authenticate(log in with UN PW info).

ACD does not use SSL, make sure it is not enabled. Default settings normally do not use SSL.

CPanel Email Accounts are configured similarly.
#Username: This will be your full email address with @DOMAIN.com at the end.
#Password: Make sure it's right!
#Incoming Server: This is normally mail.DOMAIN.com on port 110.
#Outgoing Server: This is normally mail.DOMAIN.com on port 25.
#Outgoing server needs to authenticate(log in with UN PW info).
*CPanel supports some alternate configurations, including IMAP.

Demarcation Point and Division of Responsibilty past the Network Interface

2012-08-05T09:08:28Z

Henry.joshua:

*A Network Interface is the location where the communication company hands off service to the customer's internal wiring.
*A Demarcation Point is the location where ACD's responsibility for debugging and troubleshooting ends and where the responsiblity of the Customer begins.

You can find more information about a Network Interfaces and Network Interface Devices here: http://en.wikipedia.org/wiki/Network_interface_device

==Demarcation Point Description and Division of Responsibility==

A Demarcation Point is delineates a division of responsibility for troubleshooting.

A Network Interface is the hand off point from a telecommunications company. In some occasions, where ACD is providing DSL, T1 or EFM service to customers, we use a Wirecenter Provider, which is responsible for providing ACD wires and equipment to get from your location to our network. Usually, when ACD provides Fiber Optic Service, we are also the Wirecenter Provider, and ACD directly provides our own wiring. A Network Interface refers to the point where a telecommunications or cable company hands off to ACD.

A Demarcation Point and a Network Interface can be at the same point, but don't necessarily have to be.

For example, on the '''Service Provider Side''' of the [[Network Interface]], ACD is responsible for the quality of the connection. On the '''Customer Side''' of the [[Network Interface]], the Customer is responsible for the connection.

The point where responsibility ends and a hand off of responsibility to another party is called the [[Demarcation Point]].

'''Division of Responsibility for Network Elements:'''
<pre>
Wiring Problem Equipment Problem Damaged/Lost Equipment or Wiring*
ACD Network ACD ACD ACD

Demarc Extension Customer Customer Customer
ACD owned [[Customer Premise Equipment]] N/A ACD Customer
Customer owned [[Customer Premise Equipment]] N/A CUSTOMER Customer
Inside Wire Customer N/A Customer
Customer provided handset Customer Customer Customer
ACD provided Handset under term agreement Customer ACD Customer

Notes:
* Customers in general are responsible for housing and securing ACD owned equipment. If the equipment is lost, stolen, or damaged,
usually the customer is responsible for replacing at their own cost. All ACD equipment should be kept in a secure location. The
equipment deployed at a customer site is actually owned by ACD, unless the customer has purchased their own equipment.

In general, ACD's responsibility for wiring ends at the Network Interface. If there are problems with your service beyond the Network Interface, the wiring is generally the customer's issue.

A dispatched technician will test at the network interface to prove or disprove service works at the network interface. After that point, the wiring is the customer's responsibility.

In some instances ACD can repair the wiring. However, any such repair will be charged a fee for repair or debugging, and may be assessed a [[Truck Roll Fee]].

==Division or Responsibility For IPBX Hosted VOIP Service==

This service provides phone handsets to customers, which puts these handsets inside of the customer's buildings, usually at their desks.

==Demarcation Wiring Extension==

Demarcation Wiring Extentions, also called '''Demarc Extenstion''', is an extension of wiring from the [[Network Interface]] to the [[Customer Premise Equipment]].

A Demarc Extension goes:
*'''[[Outside to Inside Demarc Extension]]''': If the [[Network Interface]] is outside of the building, the wiring that goes from the outside to the inside is a [[Demarc Extension]]
*'''[[Inside to Inside Demarc Extension]]''': If the [[Network Interface]] is inside of the building, the wiring that goes from the [[Network Interface]] to the [[Customer Premise Equipment]] is a Demarcation Extension.

ACD charges for performing Demarc Extensions, and also charges for debugging Demarcation Extensions to the Customer via a [[Truck Roll Fee]]

If the below circumstances are met, ACD may waive the [[Truck Roll Fee]].

*The Demarc Extension was performed by ACD.
*No modifications were performed on the Demarc Extension, by non-ACD personnel at any time.
*There are no other provider's services running or operational on the [[Demarc Extension]].
*The Customer is a Business Services Customer.
*The Customer is under an Active Term Contract.
*There is no damage caused on the line.
*The Wiring, whether installed by ACD or not, conforms to the [[Demarc Extension Wiring Specifications]].

If these above conditions are met, ACD will waive the [[Truck Roll Fee]] on ACD owned Demarc Extensions.

==Ordering Circuits to a Specific Network Interface==

When placing orders for circuits to an Address, ACD does not have the ability to specify and/or require to a Telco '''which''' Network Interface Device or with what Demarcation point. We cannot order to a specific Network Interface under most circumstances.

==Getting a new Network Interface==

'''Existing Building:''' For an existing building, the customer can request a new network interface through the existing wirecenter telco. In any event, this is going to cost money. The telco companies do not install new network interfaces or relocate them for free. In addition, the serving telco is not '''required''' to put in a new network interface, if the existing network interface is functioning properly. If you want a new or different network interface, please contact ACD.

'''New Building:''' For a new building where there is not a network interface in existence, there will be a cost to install the network interface from the [[serving wirecenter telco]]. The [[serving wirecenter telco]] can legally charge these fees. These fees usually include the expense to trench new cable, put in conduit, wire panels, and possibly electronics. Please contact ACD if you have a new building and need a Telco network interface. If fees have not been paid to the serving wirecenter telco, or to ACD to forward on to the serving wirecenter telco company, ACD will not be able to provision service, even after the Network Interface.

Faxing How-to and Troubleshooting

=Faxing and VoIP - Tricks of the Trade=
Faxing has been around for years and most of the protocols were written in an age when faxes traveled over a "traditional" voice network. In today’s world, the majority of telephone calls are, at some point, converted between a VoIP and traditional voice service and back again. Every portion of the ACD network is setup with full Quality of Service. This ensures that the voice and data on the ACD's network span is reliable. While we strive to create the most efficient Internet and Voice network, we can't control what happens when it leaves our network and hops on the rest of the Public Network.

In the Internet world, voice is first converted to packets, which are sent over the connections that make up the Internet. These packets may take a separate routes, thus arriving at slightly different times. In doing so, some packets may be discarded, but the end result is that the receiving VoIP device has enough information to make the call clear and indiscernible from a normal call. To ensure the best fax quality, follow the steps below. These same troubleshooting and configuration principals apply to alarm system lines, elevator emergency lines, credit card machines, postage machines and anything else that uses a Plain Old Telephone Service line for data.

It's not just our end of the network that matters. Two fax machines with the same fast setup running on VoIP can often train with each other so that they can begin transmission, but because of the inherent problems with today’s networks and VoIP, the transmission gets interrupted. If you set your machine up to work properly within a VoIP world, it will by default, train the other machine to use the same settings. This will greatly increase probability of a smooth Fax Transmission.

==Recommendations on how to configure your fax machine for best results==

At ACD.net we use the latest VoIP fax codecs (codec is a computer term that means to encode) to make our end as robust as possible. That being said, following are some items you can do on your end to help make faxing run smoothly:

* Set the baud rate on the fax machine to a slightly lower speed. Generally, 9600 bps is great. It’s different on various fax machines, but you can look for the baud rate or speed setting(9.6Kbps) that specifies V.29 or V.17. In general, fax machines set for V.34, may have echo cancellation and it is unlikely to work, as the slight delay in VoIP will make training between fax machines more difficult.
*Remove or turn off any Error Correction Mode or “ECM”.
*Try enabling Overseas Mode.
*Change the resolution from fine to standard; this will also speed up the rate at which fax machines transfer data by decreasing the size of the transmission.

If you can't figure out how to change your fax machines settings, you can either contact the manufacturer or usually you can put the model number into Google for the manual.

==Let ACD know the line you are using is going to be used for fax, data or modem use==

Within our phone switch, we are able to configure a line for fax/data/modem use. Basically, this means that by default the phone call on this line will not be compressed. Although this uses more bandwidth, it generally will produce more reliable results. If you are not sure that we have your line profile setup for fax as a default, please contact us, and provide us with your phone number and a technician can configure this in our phone switch in a matter of moments.

==What ACD needs to know to troubleshoot a Fax line issue==

We need to know the following information in order to be able to troubleshoot a fax send and receive issue. Having this information greatly speeds our ability to perform troubleshooting, and helps make sure [[Customer Support]] looks at the correct issues.

* Is the problem sending faxes, receiving faxes or both?
* What is the ACD number you are faxing from?
* Are you having problems sending faxes to only certain numbers or all numbers?
** If only to certain numbers, we need the specific numbers.
* Providing call examples(number dialed, number dialing from, and timestamp) gives us the info we need to look up a specific call in our phone switch. We can then determine the reason for disconnect.
* Is it happening at a specific time of day?
* When doing testing it is best to consistently use the same length of fax.

==Adjusting the Audio Levels both on the fax machine and on ACD equipment==

The audio levels can be adjusted on the fax machine and on the phone line ACD provides.

==Recommended Test Fax Form==

If you wish to test faxes to and from ACD, please fax us at 517-999-3993.

How to check your DSL and EFM line speed

2012-08-05T08:40:25Z

Henry.joshua:

==This document covers the following services==

*[http://www.acd.net/adsl2.cfm ADSL2+ Service]
*[http://www.acd.net/reachdsl.cfm REACH Long Range DSL Service]
*[http://www.acd.net/efm.cfm Ethernet First Mile Service]

==How to check your Line Speeds on DSL and EFM==

#Log into http://myaccount.acd.net
#Click on "Manage Services"
#Scroll down to find your DSL account. It will be listed by the circuit ID and the Address.

A description of the DSL Line Statistics:
*'''Label''' = This is the label that we assign for internal tracking purposes, and is the card and port on the DSL gear at the Central Office.
*'''Admin Status''' = This means whether the line is configured to be up or down in our equipment.
*'''Oper Status''' = This tells if the DSL line is actually up or not.
*'''Download Speed''' = This is the speed that the line is synchronized at, for your download speed.
*'''Attainable Rate''' = This is the maximum speed that the line can attain. In general, attainable rate is never achieved because the difference between the attainable rate download speed is where we create some margin for error. If these numbers are the same, then there is no margin for errors that may occur on the line.
*'''Profile''' = This lists the type of line profile that is programmed in our equipment.
*'''Downstream Attenuation''' = This is the amount of noise that is on a line.
*'''Upstream Attenuation''' = This is the amount of noise on a line.
*'''Downstream SNR''' = This is the Downstream Signal to Noise Ratio. In general, we seek to have a SNR greater than 6.0. A higher number means the line will be more reliable, but also slower. A lower number means the line will be less reliable, but may be faster.
*'''Upstream SNR''' = This is the Upstream Signal to Noise Ratio. In general, we seek to have an SNR greater than 6.0.
*Both the Downstream SNR and Upstream SNR should be higher than 6.0.

Debugging Routing Issues

2012-08-05T08:37:46Z

Henry.joshua:

This page is used by both ACD Network Operations Center personel and also by our customers to assist and facilitate the resolution of IP Block Routing Issues.

Reasons for Routing Issues:

#Many times these issues are caused by mis-configuration, either on ACD equipment or on customer equipment.
#There are some instances where routing issues are caused when ACD redundant network paths fail, and the configuration settings are not configured to flow traffic down these redundant routes successfully.
#Additionally these problems can occur when there is a [[Double Assigned IP Address or Block]]
#There are some instances where there is route corruption on ACD's or customer's network equipment. This occurs when there are database errors within the routers themselves. Usually the command "clear ip route" can resolve the issue, or reloading the respective router. Generally, this should be a last resort.

Regardless, these problems are solvable.

Debugging Ethernet Port Duplex and Speed Settings

2012-08-05T08:35:15Z

Henry.joshua:

Ethernet Port Duplex and Speed Settings are '''''the most common reason customers report speed or bandwidth issues''''' to their location. This also is the most common reason that there are [[Voice Line Quality of Service Issues]], [[Speed or Performance Issues]], or problems when we deliver SIP Trunks.

==What Duplex Settings Are==

Duplex refers to the way an ethernet port is configured. to send and recieve data

*'''Full Duplex''', means that the ethernet connection is properly configured to allow '''simultaneous''' two way traffic on your ethernet line. This is bidirectional, or two-way communication.
**In order to get the best speeds you '''must''' have your equipment configured for full duplex.
*'''Half Duplex''', means that the ethernet connection is configured to send or receive traffic, but not at the same time. This is different from simplex, or one-way communication.
**Half Duplex, will result in impaired and slower performance.

==Effects of setting "Half Duplex" communication==
* You are almost guaranteed to have slower speeds. Typically a Half-Duplex setup will decrease speeds by at least 20%, perhaps higher, particularly on faster connections. On [http://www.acd.net/fiber.cfm Fiber Speed] Connections your performance will definitely be degraded, and most high speed Ethernet Service, including [http://www.acd.net/adsl2.cfm ADSL2+] and [http://www.acd.net/efm.cfm Ethernet First Mile]
* [Speed Tests http://www.acd.net/speedtest.cfm] will result in lower speeds.
* If you are running Voice Over Internet Protocol, [http://www.acd.net/sip.cfm SIP Trunks] or [http://www.acd.net/pbx.cfm Hosted PBX], you almost always will have degraded voice. Problems with Voice will occur more often when there is high traffic load.

==How to configure your connection for full duplex==

There are a lot of incompatibilities related to devices properly negotiating speed and duplex. Usually it is best to manually set the speed and duplex on both ends of the connection, but not always.

If you have a Cisco Router, the Cisco IOS Command Line below is an example of how you would type the commands on the ethernet interface for the speed and duplex.

Pinging with Fping and Collecting Ping Performance Data

2012-07-21T01:40:25Z

Henry.joshua:

Fping is a command line application that allows for data collection and recording of the ping command data. It is basically like Ping, but is better, and has more features and functions. The most important feature is to log pings with time and date stamps to a file. In addition, it provides an accurate millisecond calculation on the ping command. FPING also supports 64 bit operating systems.

*Download the file here http://www.kwakkelflap.com/downloads.html
*From the drop down menu, select fping. Download the files and install in a directory, usually I put it in c:\fping.

==Limitations of Windows Based PC's for Reliable Ping Testing==

Pings are the very lowest priority packet for doing testing. This is the '''curse of collecting ping data''', but it is also a benefit of collecting ping data. Ping drops can occur due to any reason, including the source and destination's processing capability.

Pings take into account the cycle time through all routers and PC's. You will never obtain 100% low ping times on routers or PC's, because they are often doing other things. Average is what is important.

Windows based PC's do not guarantee processor queues for any specific ping applications. Lost packets either on the send or the return of ping packets is common and to be expected on all windows PCs, as there is no dedicated processing at the network layer. In addition, determining why a ping was lost cannot be reliably determined on a Windows PC. The device where we can reliably obtain this, because there are specific counters for each packet drop type, is on Cisco IOS routers.

Data should be considered suspect on Windows based PC's. We recommend using the 64 bit ping application if your operating system is compatible with 64 bit.

What we know does provide accurate testing via packet loss is Cisco IOS Router, and dedicated linux testing tends to work better, because there is less of an operating system to go through (i.e. gui, etc) to get to the network card.

In general, reliable ping testing should primarily be performed on Cisco IOS capable routers.

'''We are in the process of testing fping compared to ping, and seeing if there is a way to make sure the buffer queues are adequate to guarantee processing of all low priority packets. This is pending as of 03/20/12'''

==Data relied upon for debugging or troubleshooting==

*ACD does not utilize the default command line application for ping testing or packet loss. This application does not provide any logging or correlation for the data collection. We need timestamps that are accurate to correlate to any issue we may be able to detect in the logging.

*ACD does utilize and accept FPING data with the above Windows caveats. We need the text file that has been run on the standard command structure as described in this document.

*ACD does prefer Cisco IOS ping data tests above all else and that is what we principally do debugging upon.

==Command Structure==

In command prompt type: cd C:\fping\x86 (32 bit) or cd C:\fping\x64 (64 bit) based on what processor you have.

The command structure that should be used:

*fping xxx.xxx.xxx.xxx -D -c -s 1500 -L name-of-log-file.txt
**Where xxx.xxx.xxx.xxx is the ip address of the device you are pinging.
**This will create a timestamped file.
**-s 1500 sends 1500 byte pings, which is the maximum normal size. If you cannot send 1500 byte pings, there is something wrong somewhere on the network you are using.

Mail the log file created by fping to support@acd.net.

==How to use Ping testing ==
*In general you should open multiple ping windows to various hosts simultaneously. What matters most, is a consistent pattern of traffic issues to multiple devices '''THAT OCCUR AT THE SAME TIME'''. For example, if there are dropped or delayed packets all at the same time between multiple hosts, this more reliably shows that there is a problem.
*What matters most is not that one host dropped or delayed a packet; '''what does matter''' is when multiple hosts dropped or delayed a packet from your PC or site '''at the same time''', this is why having timestamps is critical. For this reason you must have multiple pings going at once to be able to correlate any data.
*'''Pinging ACD routers or ACD gateways will not result in good testable data, from the standpoint of high ping times.''' This is simply the case because our routers are busy doing other more important things than responding to customer requested pings. They are programmed to focus on shipping data and are programmed to delay or ignore your ping traffic when they are busy. It is common to see spikes in the responsiveness of pings in the range of 200-300ms for periods of time because these routers are running tasks and their responsiveness to ping requests is lower. Certain processes that run on a consistent cycle, such as BGP route updates or OSPF route updates will consistently spike the ping times for short periods of time, this is consistent and normal. When we don't see this when examining data, this is a cause for concern.
*Pinging websites like www.yahoo.com and www.google.com will also generally not produce good data. They don't want to waste all their precious CPU cycles returning pings.

==What to Ping==
On ACD systems you can ping these ip addresses. The platform is listed below as of the time of this writing.

*iperf.acd.net (Linux Platform)
*voip.acd.net (Phone Switch)
*switch.core.metroix.net (Cisco IOS 6509, SUP720-3B, max memory)

Bandwidth or Speed Testing

2012-07-21T01:29:53Z

Henry.joshua:

For some basic information about speed testing click here: http://www.acd.net/speedtest.cfm.

'''"Speed Testing"''' is a common thing end-users do to see what speed of connection they have on the Internet. However, Speed Tests that are hosted on the public Internet are not always of high quality. This is because the speed test often does not have accurate servers or systems, and also the number of hops from your computer to the speed test server can dramatically affect the results.

There are several ways to "Test" your speed, with varying accuracy and quality.

*[[Iperf Speed Testing]]. This is a highly reliable way to do an accurate speed test, however, it requires some configuration and knowledge. If you want to do speed debugging, then please click on the link. All performance testing done by our [http://www.acd.net/noc.cfm Network Operation Center] is performed using this testing. This is the same speed testing ACD uses internally, and is the general debugging mechanism used by ACD to debug all connection bandwidth issues.

*http://www.speedtest.net and [http://speedtest.acd.net http://speedtest.acd.net]. This is a browser based interface. No browser based interface is going to be highly accurate, especially at high speeds, including these common consumer speed tests. However, it provides results quickly. The advantage with browser based speed tests is that they work through firewalls. However, they do not work accurately, primarily because they a) utilize only one udp stream b) and the tests operate for only a very short period of time. These speed tests are not accurate for:
**any bonded types of connections, or link sharing technology.

Testing Connection Quality

2012-07-21T01:27:14Z

Henry.joshua:

There are a few functions that determine the "quality" of your connection from your service provider. In order to determine if the quality of bandwidth you are receiving is of high quality, there are a few tests that you can do.

The main components of connection "quality" are:

*'''Speed or Bandwidth of a Connection''': This is usually erroneously referred to as speed. Bandwidth is the correct term. For testing bandwidth go to: [[Bandwidth or Speed Testing]]
*'''Packet Loss''': This determines how many packets you loose between two points. Packet loss is generally more important than "Speed" or Latency. Having packet loss affects the Speed or Bandwidth of a connection because your computer and network components have to do more work to retransmit failed packets.
*'''Latency''': This is the variation in the packets transmission on a connection. When there is large variation between the packets sent between two points, this can affect critical services such as VOIP or SIP Trunking.

Iperf Speed Testing

2012-07-14T21:05:16Z

Henry.joshua: /* Installing Iperf */

== What it Is ==

Iperf is an industry standard tool for doing accurate speed testing. This tool is accurate and provides clear metrics to understand and use the performance metrics it produces. Iperf is open source code, and is publicly available. Please read carefully the information contained in this document, as modifications from the standards used may affect the results substantially.

*Iperf is the command line version.
*Jperf is a Graphical User Interface version that uses Iperf.

*Public Source Information about Iperf is located here: http://en.wikipedia.org/wiki/Iperf
*ACD's Iperf server is iperf.acd.net

== Speed Test Software, Websites and Issues with Getting Accurate data ==

There are many types of speed test softwares, with varying degrees of accuracy. Additionally, there are speed testing websites, these websites are inherently innaccurate, and do not provide a scientific or reliable data for troubleshooting. While sometimes usesful, websites such as http://www.speedtest.net and http://speedtest.acd.net (which is part of the speedtest.net network of server) will not provide accurate speed results on many types of connections, including wifi, bonded T1 lines, and many EFM services. Although ACD participates in speedtesting websites such as speedtest.net thier usufullness is limited. These sites will not provide accurate speeds for services faster than 40-100mb/s.

ACD uses IPerf as the standard software for doing all performance testing. For debugging purposes, ACD only uses Iperf. We do not rely upon random "speed test" websites for debugging purposes.

Changing variables within Iperf also change the performance results, often quite dramatically. Based upon our lab results, please provide us data with the Recommended Settings for Testing below. Data without the recommended settings and time stamps will generally not be taken into account for troubleshooting.

=== Recommended Settings for Testing ===

This command will run 10 parallel client threads over 240 seconds (4min).

'''iperf -c iperf.acd.net -P 10 -t 240'''

== Servers on ACD.net's Network Configured for iperf ==

iperf.acd.net

== Installing Iperf ==
*[[File:Iperf.zip]]
Download IPerf, unrar and install into '''c:\iperf\'''

For Windows XP and Windows 7, all you need to do is unzip the files and move them to your newly created iperf directory(folder).

Example:
Create a new folder in your C Drive called iperf.
C:\iperf

Unzip the files and move them to C:\iperf.

Open a command prompt(Win>Run>cmd) and change directories(cd) to the C drive(c:\) under the iperf directory(c:\iperf)

Run your iperf testing(iperf -c iperf.acd.net -P 10 -t 240)

== Getting Started ==

To begin using iperf, open up the command prompt and change to the iperf directory by typing '''cd c:\iperf'''.

=== Server Setup (Windows) ===

If you are testing to the ACD server (iperf.acd.net), you do not need to install your own server. If you are planning on running your own server; the servers should not have a lot of other applications or software or active usage to get test results.

If you are going to run your own server; To begin transmitting files between two locations, one machine must be designated the server, while the other must be the client. The command to designate one machine as the server is as follows:
iperf -s

The full command line at this point should read as follows:
C:\iperf>iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 8.00 KByte (default)

This setup is useful for creating a temporary iperf server for an iperf client to test to. It does not, however, set up a persistent server that will be up and online automatically whenever the machine is.

=== Client Setup (Windows) ===

In order for the second machine to run in client mode, the following command will be entered into the command prompt:

iperf -c [server IP address -or- Hostname]

At this point the client will connect to the server and transfer a single file for the default period of 10 seconds.

C:\iperf>iperf -c 69.63.233.183
------------------------------------------------------------
Client connecting to 69.63.233.183, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1832] local 69.63.233.182 port 3716 connected with 69.63.233.183 port 5001
[ ID] Interval Transfer Bandwidth
[1832] 0.0-10.0 sec 109 MBytes 91.7 Mbits/sec

== Client Arguments ==
The iperf client supports a great deal of arguments that allow for the transfer to be customized in a number of ways. The following section covers these arguments in detail:

=== Using Single Arguments ===

==== Changing the duration of transfer: ====

To change the duration of the transfer from the default value of 10 seconds, the argument '''-t #''' can be added to the end of the client command, where '''#''' represents the duration in seconds.

C:\iperf>iperf -c iperf.acd.net -t 5

This argument would transfer data to the server for 5 seconds instead of the default 10 seconds.

==== Changing the interval rate: ====

The interval at which data is transferred to the server can be set by using the argument '''-i #''' where '''#''' represents the period in seconds for each interval.

C:\iperf>iperf -c 69.63.233.84 -i 2

This argument would transfer data to the server for 10 seconds (default), and display the data in intervals of 2 seconds (-i 2)

==== Transferring a specific file size: ====

To transfer a file via iperf based on a specific file size as opposed to a duration, the argument '''-n #''' is used, where '''#''' represents the file size in bytes. You can also use '''-n #M''' or '''-n #K''' to enter transfer size in Mbytes or Kbytes.

C:\iperf>iperf -c netflow01.acd.net -n 100000

Will display like:

------------------------------------------------------------
Client connecting to netflow01.acd.net, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1908] local 69.63.233.190 port 3605 connected with 207.179.118.136 port 5001
[ ID] Interval Transfer Bandwidth
[1908] 0.0- 0.0 sec 104 KBytes 54.5 Mbits/sec

And

C:\iperf>iperf -c netflow01.acd.net -n 100M

Will display like:

------------------------------------------------------------
Client connecting to netflow01.acd.net, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1908] local 69.63.233.190 port 3614 connected with 207.179.118.136 port 5001
[ ID] Interval Transfer Bandwidth
[1908] 0.0- 8.9 sec 100 MBytes 94.0 Mbits/sec

==== Bidirectional testing: Individually ====

To test both directions of the transfer, one direction at a time, the argument '''-r''' is used.

C:\iperf>iperf -c 69.63.233.182 -r

This argument will test in both directions in turn and will output something like this:

------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
------------------------------------------------------------
Client connecting to 69.63.233.182, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1852] local 69.63.233.190 port 3058 connected with 69.63.233.182 port 5001
[ ID] Interval Transfer Bandwidth
[1852] 0.0-10.0 sec 110 MBytes 92.5 Mbits/sec
[1944] local 69.63.233.190 port 5001 connected with 69.63.233.182 port 2828
[ ID] Interval Transfer Bandwidth
[1944] 0.0-10.0 sec 81.9 MBytes 68.8 Mbits/sec

==== Bidirectional testing: Simultaneously ====

To test both directions of the transfer simultaneously, the argument '''-d''' is used.

C:\iperf>iperf -c netflow01.acd.net -d

Will output like:

------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
------------------------------------------------------------
Client connecting to netflow01.acd.net, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1848] local 69.89.110.216 port 2993 connected with 207.179.118.136 port 5001
[1816] local 69.89.110.216 port 5001 connected with 207.179.118.136 port 55020
[ ID] Interval Transfer Bandwidth
[1848] 0.0-130.2 sec 848 KBytes 53.4 Kbits/sec
[1816] 0.0-163.9 sec 3.13 MBytes 160 Kbits/sec

==== Running Multiple Parallel Connections ====

The argument '''-P #''' where '''#''' represents the number of parallel connections you want to run.

C:\iperf>iperf -c netflow01.acd.net -P 3

Will output like:

------------------------------------------------------------
Client connecting to netflow01.acd.net, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1872] local 69.89.110.216 port 3065 connected with 207.179.118.136 port 5001
[1888] local 69.89.110.216 port 3064 connected with 207.179.118.136 port 5001
[1908] local 69.89.110.216 port 3063 connected with 207.179.118.136 port 5001
[ ID] Interval Transfer Bandwidth
[1908] 0.0-130.4 sec 456 KBytes 28.6 Kbits/sec
[1872] 0.0-130.4 sec 264 KBytes 16.6 Kbits/sec
[1888] 0.0-130.9 sec 208 KBytes 13.0 Kbits/sec
[SUM] 0.0-130.9 sec 928 KBytes 58.1 Kbits/sec

Displaying the results port by port followed by the [SUM] with totals for the entire transaction.

==== Choosing which port to connect to or listen on ====

To set which ports to use on the client side of iperf the argument '''-p''' and '''-L''' are utilized. 
:When used by the client, the '''-p''' argument determines which port on the server to connect to using the format '''-p #'''' where # is a port number on the iperf server. 
:The '''-L''' argument lets you select which port the client will listen on in the case of bidirectional testing using the format '''-L #''' where # is a port number on the client machine. 

=== Using Multiple Arguments ===

It is possible to use iperf arguments together to have more control over the testing process and the results you receive in return. What follows are examples of some of the useful and possible combination of iperf arguments.

==== Using the interval and duration arguments together: ====

Changing both the duration of the transfer as well as the interval for the same test is as simple as adding both arguments to the command line:

C:\iperf>iperf -c 69.63.233.84 -i 2 -t 20

This argument would transfer data to the server for 20 seconds (-t 20), and display the data in intervals of 2 seconds (-i 2)
