Description   TN767E DS1 Interface, T1 (24 Channel) The TN767 DS1 interface circuit pack provides a DSX1-level physical interface to the DS1 facility and require a TN464 DS1 interface circuit pack. The TN767 circuit pack has unpolarized line out (LO) and line in (LI) signal lead pairs. The TN767 circuit pack supports DS1 rate digital facility connectivity. The circuit pack supports CO, Tie, DID, and off-premises stations (OPS) port types that use the robbed-bit signaling protocol. This circuit pack also supports ISDN-PRI connectivity. For these applications, the signaling D-channel can connect from the TN767 circuit pack to the processor interface by a permanent switched call over the TDM bus. The TN767 circuit pack is used to communicate with AVAYA IVR and to provide the enhanced maintenance capabilities of the 120A channel service unit (CSU) and the enhanced integrated channel service unit (ICSU). DS1 tests include loopback tests at the DS1 board edge or the 120A (if used), bit error rate (BER) loopback tests at the far-end CSU, and BER 1-way DS1 facility tests. Other tests include loopback testing specifically designed to locate DS1 facility faults. One year warranty. This item is also known as TN767E and 63156.
