Add TTC Japanese 2-Mbit Trunks
The TN2242 Japan 2-Mbit trunk interconnects to other vendor equipment in Japan as well as to
other switches through the Time Division Multiplexor (TDM).
Installing the trunk
To install the trunk:
1. Determine the port assignment of the trunk from the Trunk Group form.
2. Install a TN2242 circuit pack in assigned carrier slot.
3. Connect the H600-513 cable from the cabinet to the Time Division Multiplexor device.
4. To administer forms, see the following sections in the Administrator’s Guide for Avaya
Communication Manager.
● For ISDN applications, see ISDN Service.
● For non-ISDN applications, see Managing Trunks.
Add DCS Interface
Systems in a Distributed Communications System (DCS) network are interconnected by both
tie trunks (for voice communications) and data links (for control and transparent feature
information). These data links, also called DCS signaling links, support the feature
transparency.
DCS requires a special signaling connection to carry the information needed to make the DCS
features work. This signaling connection, or link, between two switches in a DCS network is
implemented either:
● over an ISDN-PRI D-channel.
● over a TCP/IP connection.
