To connect E1/T1 trunk using RJ-48c connectors, follow these 2 steps:

1Connect the E1/T1 trunk cables to the ports labeled Trunks 1 to 8 (in the case of the 8- trunk device) on the V7122 RTM.

2Connect the other ends of the Trunk cables to the PBX/PSTN switch.

RJ-48c trunk connectors are wired according to Figure 7.

Installing the Ethernet Connection

Connect a standard Category 5 network cable to the Ethernet RJ-45 port (and the other as optional redundancy/backup). Connect the other end of the Category 5 network cables to your IP network. The Ethernet connectors (labeled Ethernet 1 and Ethernet 2) are wired according to Figure 8.

When you assign an IP address to the V7122 gateway using HTTP (under Step 1 in Section Assigning an IP Address Using HTTP), you may be required to disconnect this cable and re- cable it differently.
