Regarding telephony and/or data circuits, the demarcation point is the point at which the service provider network ends and connects with the customer’s on-premises wiring. It is the dividing line which determines who is responsible for installation and maintenance of wiring and equipment, the customer/subscriber, or telephone company/service provider.
Demarcation point is sometimes abbreviated as demarc, DMARC, or similar. The term MPOE (minimum or main point of entry) is also used, with the added implication that it occurs as soon as possible upon entering the customer premises. A network interface device often serves as the demarcation point.
In most cases customers are responsible for extending telephony and/or data circuits from the demarcation point to their equipment which may be installed in their suite, in a server room, closet, or on a wall.
Typically carriers/service providers will only test up to the demarcation point. Past demarcation point it is up to the customer or their telephony/data vendor to test the circuit extension to their equipment.
Circuit extensions from the Demarcation point should only be installed or tested by companies that are licensed, insured, & bonded to perform Low Voltage cabling.
