Telephone and PBX Cross-connections

Описание к видео Telephone and PBX Cross-connections

shows how cross-connections are made from Station cabling over to the PBX. Using a one-pair 22 or 24 gauge copper jumper wire, we make "cross-connects" from the wire going out to the Telephone jack over to the ports (terminals or TN) on the PBX.

Office phones are plugged in to wall jacks. Those Wall jacks have a wire that runs in the wall, through the ceiling and over to a PBX room. Inside the PBX room, those cable come together on 66-blocks. Cross-connects are used to make the electrical connection from the Station wiring over to a particular port on the PBX.
