Description
Avaya TN760B 4-Port Tie Trunk Card ATT Lucent DEFINITY G3 PBX Module
The Avaya TN760B is a 4-port tie trunk circuit card designed for use in ATT/Lucent/Avaya DEFINITY G3-series PBX systems. Tie trunk cards provide dedicated private-line connections between two PBX systems — typically at separate company locations — allowing internal calls to be routed between sites without going through the public switched telephone network. The TN760B slots directly into the DEFINITY cabinet backplane and is managed through the system's administration software.
