Note:
Note: 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 the
Administering Avaya Aura Communication Manager (03-300509) for
information on how to administer trunks. Refer to your Avaya representative for
the correct settings for administrable timers and other parameters on a
country-by-country basis.
The DS1 tie trunk provides both voice and data communications between two PBX switches.
There are two types of DS1 interfaces:
● 24 DS0 chels on a 1.544-Mbps link
test trunk grp#/mem# long 3
WRN test trunk grp#/mem#
1. For additional repair information, see DS1-BD (DS1 Interface Circuit Pack) if the tie trunk is on a TN722 or
TN767 DS1 circuit pack. See UDS1-BD (UDS1 Interface Circuit Pack) UDS1-BD documentation if the tie
trunk is on a TN464 UDS1 circuit pack. See MG-DS1 (DS1 Interface Media Module) if the tie trunk is on a
DS1 Interface Media Module.
2. A MAJOR alarm on a trunk indicates that alarms on these trunks are not downgraded by set options
and that at least 75% of the trunks in this trunk group are alarmed.
● 31 DS0 chels + 1 framing chel on a 2.048-Mbps link
DS1 Tie Trunk
3. For TN767B vintage 8 or 9 circuit packs, a failure of Test #136 causes a subsequent failure of Test #7. Test
#136 is part of the short sequence and generates off-board alarms. Test #7 is part of the long sequence
and generates on-board alarms. Before entering busyout, release, reset or test board long commands,
check the vintage number of the circuit pack with list configuration board location. If it is
TN767B vintage 8 or 9, do not use the above commands until you ensure that Test #136 passes via test
board short. Otherwise, extraneous on-board alarms may be generated.
Note:
Note: 32-chel mode is supported only on TN464 circuit packs.
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 chel with bandwidth for voice-grade data, 56- or 64-kbps data.
DS1 tie trunk maintenance provides a strategy to maintain a DS1 tie trunk via a port on the
TN722 or TN767 DS1 Interface circuit pack, the TN464 UDS1 Interface circuit pack, or the DS1
Interface Media Module. Throughout this TIE-DS1 section, the term DS1 Interface applies to
DS1 or UDS1 circuit packs, or to DS1 Interface Media Modules.
