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
DEFINITY
Enterprise Communications Server Release 5.4 Administration and Feature
Description
, 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.
A DS1 DIOD trunk provides a link for digitized voice or data communications
between the system and a central office switch. 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
■ 32-channel mode is supported only on TN464 circuit packs and on G3r V2
systems.
The DS1-DIOD maintenance object monitors and maintains a DIOD trunk port on
a TN464 UDS1 Interface circuit pack. See "UDS1-BD (UDS1 Interface Circuit
Pack)" in this chapter for more information about this circuit pack. The DS1 circuit
pack supports low level CO trunk signaling interfaces for both ground-start and
loop-start trunks. This maintenance strategy covers the in-line errors log,
initialization tests, periodic tests, scheduled tests, demand tests, and alarm
resolution and escalation.
