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.
