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 appropriate DS1 signaling mode (for example, common channel signaling). The MM710 series Media Modules support wink-start and immediate-start trunks and call processing signaling. See MG-DS1 for more information. Throughout this section, the term DS1 applies to MM710 Media Modules.

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:


out-of-service	The trunk is in a deactivated state and cannot be used for incoming calls.
in-service	The trunk is in an activated state and can be used for incoming calls.

If the DS1 Media Module is out-of-service, then all trunks on the DS1 Interface Media Module are put into the out-of-service state and a Warning alarm is raised.
