DID-DS1 (Direct Inward Dial Trunk)
S8700 | 8710 / S8500 / S8300
The DID-DS1 trunk provides a digital Direct Inward Dial (DID) trunk from a CO switch to the
system through a DS1 link. A 24-channel DS1 link can support up to 24 DID-DS1 trunk calls
simultaneously. A 32-channel link can support up to 30.
A DID-DS1 trunk can be used for digitized voice and data communications with DS1 signaling
mode (for example, common-channel signaling). The TN767 and TN464 series circuit packs,
and the MM710 Media Module, support wink-start and immediate-start trunks and Avaya™
Communication Manager signaling. Throughout this section, the term DS1 applies to all. For
more information, see one of the following maintenance objects:
S8300 / G700 Although the DID-DS1 MO is provided for a G700 Media Gateway, the DID-DS1
only partially supports the MM710 DS1 Media Module.
Information included in this section covers the in-line errors log, initialization tests, periodic
tests, scheduled tests, system technician demand tests, and alarms escalation and elimination.
Two trunk service states are specified in the DID-DS1 trunk maintenance:
If a DS1 is out-of-service, then every trunk on the circuit pack or media module is put into the
out-of-service state, and a Warning alarm is raised.
