entrance facility
The location where an incoming network service (whether phone, Internet, or long-distance service) enters a building and connects with the building's backbone cabling.
horizontal cross-connect
Ties the telecommunication room to the end user. Specifically, the horizontal cabling extends from the telecommunications outlet, or network outlet with RJ-45 connectors, at the client end. It includes all cable from that outlet to the telecommunication room to the horizontal cross-connect. The term horizontal cross-connect refers to the distribution point for the horizontal cable.
