Connecting The Lines

The line terminations for the common equipment cabinet are standard modular plug/jack
connections. Line configuration must be loop start only. Each modular jack provides termination
for two lines. Modular line jacks 1 and 2 also provide termination for an auxiliary pair in
addition to the two outside lines. The outside line termination can be a type 66M-xx connector
block or individual 6-position modular jacks. The line cord that is routed between the outside
line termination and the common equipment termination should be twisted-pair wiring. The
J0408, J0816 and J1632 common equipment supports the installation of up to 4, 8, or 16 lines,
respectively. Add-on expansion modules are available to expand the line capacity of the systems.
