APPENDIX D: G.703 Rear Card Module

D.5 Making Interface Connections

The module provides access to a 64-kbps co-directional G.703 PCM network.
Figure D-3 shows the position of the G.703 interface and the line interface of the
G.703 rear card. This section describes how to connect the G.703 interface and the
line interface.

NOTE

The G.703 line surge protection on this unit was installed for circuit
protection only. By no means does this include the preservation of
signal quality during a large surge.
