- transmit and receive signaling messages over a DS-30X signaling channel in A10
format
• decode received messages to set configuration and activate/deactivate interface relays
for PCM loopback diagnostic purposes
• decode outpulsing messages (one per digit) from the CPU to drive outpulsing relays at
20 pps, 10 pps1 (primary), or 10 pps2 (secondary)
• monitor signals from the trunk interface and generate a message when required for each
state change
• control disabling and enabling of unit or card
• control A-Law and µ-Law operation modes
• control transmission pad settings
Maintenance features
The following features are provided for maintenance of the E and M trunk:
• indication of card status from self-test
• software enable and disable capability for individual units or entire card
• loopback of PCM signals to DS-30X for diagnostic purposes
• card ID for autoconfiguration and determination of serial number and firmware level
Operation
The optional applications, features, and signaling arrangements for each unit on the E and M
Trunk card are assigned through the Trunk Administration LD 14 and Trunk Route LD 16
programs.
Signaling and call control
The information in this section describes the signaling and call control of E and M Type I and
II trunks. The call is terminated and the trunk released by a disconnect message sent to the
associated unit.
Figure 139: Signaling orientation for tandem connection between E and M and CO trunks
on
page 442 shows the trunk signaling orientation for a tandem connection between E and M
and CO trunks.
