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. 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 and beginning
with G3r V2 systems.
The DS1-DIOD MO monitors and maintains a DIOD trunk port on a TN464 UDS1
Interface circuit pack. See
‘‘UDS1-BD (UDS1 Interface Circuit Pack)’’ on page
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.
Three trunk service states are specified by DS1 DIOD trunk maintenance:

A Major alarm on a trunk indicates that alarms on these trunks are not downgraded by the set
options command and that at least 75 percent of the trunks in this trunk group are alarmed. For
more information, see the set options command.
