1424 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
In a 24-channel system, the DS1 ISDN Trunk or PRI endpoint port (B-channels) may use any of
the first 23 ports. The ISDN-PRI Signaling Link Port must be the 24th port. In certain
configurations (NFAS), the 24th port may be used as a B-channel. Refer to ISDN-SGR
(ISDN-PRI Signaling Group) on page 1429 for further details.
A problem with an ISDN-LNK will affect every associated B channel since, without it, no
call-control information can be conveyed to the far-end switch or to a terminal adapter. Stable
calls may remain operational, but no new calls can be placed. In turn, the ISDN-LNK depends:
● S8700 | 8710 / S8500: For systems supporting circuit packs:
● On the TN464C or higher suffix UDS1 Interface circuit pack where it resides
● On the packet bus that provides the link to the processor
● S8700 | 8710 / S8500 / S8300: For systems supporting media modules:
● On the MM710 Media Module that provides the link to the processor
If there are problems with the ISDN-LNK, also investigate the TN464C or higher suffix UDS1
Interface circuit pack (UDS1-BD) and the packet bus (PKT-BUS) for systems supporting circuit
packs (
S8700 | 8710 / S8500), or investigate MG-DS1 (MM710 DS1 Interface Media Module) for
systems supporting media gateways (
S8700 | 8710 / S8500 / S8300).
