Connecting The Outside Lines To The System
The common equipment cabinet line terminations are
standard modular plug/jack connections. Each
modular jack (2-6) provides termination for two lines.
Modular jacks 2 and 3 also provide termination for an
auxiliary pair in addition to the two outside lines. Line
terminations at the demarcation point can either be at
a type 66M-xx connector block or at individual
6-position modular jacks. Table 3-l shows the line
connection details.
The tine cord that is routed between the CO line
termination and the common equipment cabinet
termination should be twisted-pair wiring.
Six-wire twisted pair cable is recommended for wiring
between the CO termination and modular jacks 2 and
3 to provide auxiliary equipment interface wiring.
To help ensure that external over-vottage
surges do not damage the system, verify
that gas discharge tubes or slmllar
protectlon devices are Installed, and
properly grounded, on all connected
outslde lines.
