Extension and Line Connections

Install station equipment connected to Digital Station and Analog Station Cards as on-premises
extensions only.
The Main Equipment Cabinet provides 8-pin mod jacks for connecting extensions and lines. Using the
Installation Cable (P/N 808920) makes it easy to connect the mod jacks to standard 66M1-50 connecting
blocks. These cables have six 8-pin modular jacks on one end and are unterminated on the other. Each jack
connects four extensions or lines.
To connect all 26 extensions and 8 lines, you'll need 3 installation cables and 3 associated 66M1-50 connect-
ing blocks.
