Demarcation Point and Division of Responsibilty past the Network Interface
- 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.

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.

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.

Demarcation Wiring Extension
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.
