TIE-DS1 (DS1 Tie Trunk)
The DS1 tie trunk provides both voice and data communications between two PBX switches. There are
two types of DS1 interfaces:
•
24 DS0 channels on a 1.544 Mbps link
•
31 DS0 channels + 1 framing channel on a 2.048 Mbps link
DS1 Tie Trunks are used widely in the Distributed Communications System (DCS) and Central Attendant
Service (CAS) system features.
A DS1 tie trunk can also be used as an access endpoint which is a non-signaling channel with bandwidth
for voice-grade data, 56 Kbps data or 64 Kbps data.
DS1 tie trunk maintenance provides a strategy to maintain a DS1 tie trunk via a port on the MM710
Interface Media Modules.
The DS1 tie trunk maintenance strategy covers logging DS1 tie trunk hardware errors, running tests for
trunk initialization, periodic and scheduled maintenance, system technician-demanded tests, and alarm
escalation and resolution. Three different trunk service states are specified in DS1 tie trunk maintenance:
Out-of-service
In-service
Disconnect (ready-
for-service)
If the DS1 Interface Media Module is out of service, then all trunks on the DS1 Interface Media Module
are also placed into the out-of-service state and a Warning alarm is raised.
