DID-DS1 (DS1 DID Trunk)
The DID-DS1 trunk provides a digital DID trunk from a CO switch into the sys tem
through a DS1 link. A 24 channel DS1 link can supp ort up to 24 DID-DS1 trunk
calls simultaneously. A 32 channel DS1 link can supp ort up to 30 DID-DS1 trunk
calls simultaneously. A DID-DS1 trunk can be used for b oth voice and d ata
communications with app ropriate DS1 signaling mod e (for example, common
channel signaling). Only the TN767 and TN464 DS1 Interface circuit pac ks
support the DID-DS1 trunk call p rocessing signaling s, wink-start, and
immediate-start.
DID-DS1 trunk maintenance provides a means to m aintain a DID trunk on a port
of DS1 Interface circuit p ack. Information include d covers the in-line errors log ,
initialization tests, periodic tests, system technician d emand tests, and alarms
escalation and elimination. Two trunk service states are spec ified in the DID-DS1
trunk maintenance. They are:
out-of-service
, the trunk is in a deactivated state
and can’t be used for inc oming calls;
in-service
, the trunk is in an activated state
and can be used for incoming calls. If the DS1 Interface circuit p ack is
out-of-service, then all trunks on the DS1 Interface c ircuit pack are p ut into
out-of-service state and a Warning alar m is raised.
