NOTE:
Many trunk problems are caused by incorrect setting s of parameters on the
trunk group administratio n form. Settings must be comp atible with the local
environment and with parameter setting s on the far-end. Refer to

DEFINITY

Enterprise Communications Server Administrator’s Guide

for information on
how to administer trunks. The Applic ation Notes section of that book sh ows
the correct settings for ad ministrable timers and other p arameters on a
country-by-country basis.
A DS1 DIOD trunk provides a link for dig itized 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 c hannel on a 2.048 Mbps link
■32-channel mode is supp orted only on TN464 circuit p acks and on G3r V2
systems.
The DS1-DIOD maintenance object monitors and maintains a DIOD trunk port on
a TN464 UDS1 Interface circuit pac k. See UDS1-BD in this chapter for more
information about this circ uit pack. The DS1 circuit pac k supports low level CO
trunk signaling interface s for both ground-start and loop-start trunks. This
maintenance strategy cov ers the in-line errors log, initialization tests, per iodic
tests, scheduled tests, d emand tests, and alarm resolution and escalation.
