2Connect the E1/T1 trunk interfaces (see Connecting the E1/T1 Trunk Interfaces).

3Install the Ethernet connection (see Installing the Ethernet Connection).

4Connect the power supply (see Connecting the Power Supply).

Connecting the E1/T1 Trunk Interfaces

Connect the V7122 gateway E1/T1 Trunk interfaces using either Telco or RJ-48 connectors:

To connect E1/T1 trunk interface using 50-pin Telco connectors (16-trunk device), follow these 3 steps:

1Attach the Trunk cable with a 50-pin male Telco connector to the 50-pin female Telco connector labeled Trunks 1Æ8 on the Rear Transition Module (RTM).

2Connect the other end of the Trunk cable to the PBX/PSTN switch.

3Repeat 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 pinouts described in Table 5, and to mate with the female connector illustrated in Figure 6.
