DID-DS1 (DS1 DID Trunk)
The DID-DS1 trunk provides a digital DID trunk from a CO switch into the system
through a DS1 link. A 24 channel DS1 link can support up to 24 DID-DS1 trunk
calls simultaneously. A 32 channel DS1 link [G3iV2-386] can support up to 30
DID-DS1 trunk calls simultaneously. A DID-DS1 trunk can be used for both voice
and data communications with appropriate DS1 signaling mode (for example,
common channel signaling). Only the TN767 and TN464 [G3iV2-386] DS1
Interface circuit packs support the DID-DS1 trunk call processing signalings,
wink-start, and immediate-start.
DID-DS1 trunk maintenance provides a means to maintain a DID trunk on a port
of DS1 Interface circuit pack. Information included covers the in-line errors log,
initialization tests, periodic tests, system technician demand tests, and alarms
escalation and elimination. Two trunk service states are specified in the DID-DS1
trunk maintenance. They are:
out-of-service
, the trunk is in a deactivated state
and can’t be used for incoming calls;
in-service
, the trunk is in an activated state
and can be used for incoming calls. If the DS1 Interface circuit pack is
out-of-service, then all trunks on the DS1 Interface circuit pack are put into
out-of-service state and a Warning alarm is raised.
