It is important to label all demarc extension connections and interconnection points throughout the demarc extension. This will minimize servicing time which is a critical factor in fault isolation and circuit restoration.

Demarc Extension Nationwide has developed the following standards to be adhered to when installing and servicing a demarc extension.

• All labeling is required to be mechanically printed on a permanent label or legibly hand-written with a permanent marker.
• Demarcation Points shall be labeled with the Local Access Provider’s circuit identification number (ID).
• Demarc Connection Points shall be labeled with the Local Access Provider’s Circuit ID, Carrier ID Number and Vendor Cable ID Number.
• All cross-connections, interconnections, and intraconnections shall be labeled with a minimum of the Vendor Cable ID Number.
• Edge Termination Points shall be labeled with the Local Access Provider’s Circuit ID, Carrier Circuit ID Number and Vendor Cable ID Number.
• Additional labeling standards based on customer requirements may be imposed.
