1. A Major alarm on a trunk indicates that alarms on these trunks are not downgraded by set options
and that at least 75 percent of the trunks in this trunk group are alarmed.
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-chel DS1 link can support up to 24 DID-DS1 trunk calls
simultaneously. A 32-chel 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-chel signaling). The TN767 and TN464 circuit packs and the DS1
Interface Media Module support wink-start and immediate-start trunks and Communication
Manager signaling. Throughout this section, the term DS1 applies to all. For more information,
see one of the following maintenance objects:
Circuit Pack/Media Module Maintenance
Object
TN767 DS1 Interface Circuit Pack DS1-BD
TN464 UDS1 Interface Circuit Pack UDS1-BD
DS1 Interface Media Module MG-DS1
Not all tests that run on circuit packs are applicable to media modules. These tests will abort
with error code 1412. This error can be ignored.
Two trunk service states are specified in the DID-DS1 trunk maintenance:
out-of-service The trunk is in a deactivated state and cot be used for
incoming calls.
in-service The trunk is in an activated state and can be used for
incoming calls.
If a DS1 is out-of-service, every trunk on the circuit pack or media module is put into the
out-of-service state, and a Warning alarm is raised.
