DIOD-DS1 (DS1 DIOD Trunk)
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’s Guide for Avaya MultiVantage Software 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 ch 1 framing channel on a 2.048 Mbps link
■
32-channel mode is supported only on TN464 circuit packs.
The DS1-DIOD maintenance object monitors and maintains a DIOD trunk port on
a TN464 UDS1 Interface circuit pack. See UDS1-BD 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.
