The NT8D14 Universal trunk Card is an Intelligent Peripheral Equipment
(IPE) device that can be installed in either the NT8D37 IPE Module or the
NT8D11 CE/PE Module. The Universal Trunk card interfaces eight analog
trunk lines to the Meridian 1 switch. Each trunk interface is independently
configurable by software control using the Trunk Administration program
LD 14.
The universal trunk card supports the following trunk types:
•
Centralized Automatic Message Accounting (CAMA) trunks
• Central office (CO), Foreign Exchange (FEX), and Wide Area
Telephone Service (WATS) trunks
• Direct inward dial (DID) trunks
•
TIE trunks: two-way loop dial repeating (LDR) and two-way loop
outgoing automatic incoming dial (OAID)
•
Recorded Announcement (RAN) trunks
• Paging trunks
The universal trunk card also supports Music, Automatic Wake Up, and
Direct Inward System Access (DISA) features.
Table 204 "Trunk and signaling matrix" (page 485) lists the signaling and
trunk types supported by the universal trunk card.
