4.1 Connecting The Lines
How to
connect the
lines
Line terminations to the line boards are through a 50-pin amphenol-type connector. The
demarcation point can be a type 66M-xx connector block or individual 6-position modular jacks.
The wiring that you route between the demarcation-point and the line board termination should be
#24 AWG or larger twisted-pair wiring.
