Log)
Many trunk problems are caused by incorrect settings of parameters on the trunk group
administration form. Settings must be compatible with the local environment and with parameter
settings on the far-end. Refer to Administrator Guide for Avaya Communication Manager,
03-300509, for information on how to administer trunks. For the correct settings for
administrable timers and other parameters on a country-by-country basis, see your local Avaya
representative.
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
Alarm Level Initial Command to Run Full Name of MO
TIE-DS1* MAJOR** test trunk grp/mbr l DS1 Tie Trunk
TIE-DS1 MINOR test trunk grp/mbr l DS1 Tie Trunk
TIE-DS1 WARNING test trunk grp/mbr DS1 Tie Trunk
*See MG-DS1 documentation if the tie trunk is on a MM710 media module media module.
**A MAJOR alarm on a trunk indicates that alarms on these trunks are not downgraded by
the set options command and that at least 75% of the trunks in this trunk group are
alarmed.
● 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.
