Central Office (CO) Line Installation
The system connects to the telephone company lines using a two-wire (single pair) cable,
connected to a RJ11 or RJ21X, then connected to the built in MDF Patch Panel on the
motherboard.
Surge Protection Considerations
Transitory voltage spikes, if induced onto CO lines, can travel through the cable and into
the common equipment. The telephone company offers basic protection against this condi-
tion, but it is usually designed to protect the CO circuits and should, therefore, not be
relied upon for total protection. To help protect the system from external voltage surges,
the manufacturer recommends that gas discharge tubes, or similar primary protection
devices, be installed and properly grounded on all lines.
Adding a Music Source
A music source can be connected to the MOH/BGM (External Music) port using the sup-
plied 3.5 mm connector.
