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 Administrator 
Guide for Avaya Communication Manager, 03-300509 for information on how to 
administer trunks. The Application Notes section of that book shows 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 channels on a 1.544-Mbps link

●

31 DS0 channels + 1 framing channel on a 2.048-Mbps link

Note:

32-channel 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 channel 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

1. For additional repair information, see 

on page 978 if the 

tie trunk is on a TN722 or TN767 DS1 circuit pack. See 

on page 2374 UDS1-BD documentation if the tie trunk is on a TN464 UDS1 circuit pack. 

on page 1594 if the tie trunk is on an MM710 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.

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.
