Connect the E1/T1 Trunk Interfaces using either Telco or RJ-48 connectors:
¾ With 50-pin Telco connectors (16-trunk device), take these 3 steps:
1. Attach the Trunk cable (of at least 26 AWG UTP) with a 50-pin male Telco connector
to the 50-pin female Telco connector labeled ‘Trunks 1Æ8’ on the Rear Transition
Module (RTM).
2. Connect the other end of the Trunk cable to the PBX/PSTN switch.
3. Repeat steps 1 and 2 for the other Trunk cable but this time connect it to the
connector labeled ‘Trunks 9Æ16’.
The 50-pin male Telco cable connector must be wired according to the pinout in Table
3-3
below, and to mate with the female connector illustrated in Figure
3-5.
