In telecommunications, a demarc extension is the transmission path originating from the interface of the access provider's side of a telecommunications circuit demarcation point within a premise and ending at the termination point prior to the interface of the edge Customer Premises Equipment (CPE). This may include in-segment equipment, media converters and patch cords as required to complete the circuit's transmission path to the edge CPE.

J&J Communications provides all services and equipment necessary to connect the circuit to your internal network equipment, including Demarc Extensions -- the transmission path from the access provider's Demarcation point to the edge of the end user's network.  We provide facility cabling, circuit testing and maintenance.
