Voice card/channel problems
Channel status is
Faulty or
OutOfService
If the channel status is Faulty or OutOfService, follow these
steps.
Note: The term “voice card” used below refers to either a
VP8 or a VP4.
Step Action
1 Check the network loop cable connections along the network
loop path between the backplane of Meridian Mail to the
QPC414 in the Meridian 1.
2 Check all the jumper blocks on the backplane to make sure
they are secure. See Chapter 8, “Configuring the backplane
and inspecting the printed circuit packs,” for further information
on the placement of all jumpers.
3 Verify that the voice cards are installed in the correct nodes and
are properly seated.
4 Verify the database in Meridian 1 and the Channel Allocation
Table (CAT) table.
5 Check for DTA100 code on the Meridian 1 console. Refer to the
X11 Input/Output Guide
(NTP 553-3001-400) for an
explanation.
6 Check the status of agents in Meridian 1 (in Overlay 32) on the
Meridian 1 console.
a. L S C U (L=loop, S=shelf, C=card, U=unit)
b. Verify that each unit shows IDLE (log-in).
c. If each unit does not show IDLE,
DIS L S C U (disable loop, shelf, card, and unit)
d. ENL L S C U (enable loop, shelf, card, and unit)
Note 1:
You should see message DTA101 if the agent was
disabled.
Note 2:
For any error messages received during this
process, refer to the
X11 Input/Output Guide
(NTP 553-3001-400) for the appropriate action.
7 Disable each voice card and perform out-of-service diagnostics
on each card. See your
System Administration Guide
(NTP 555-7001-30x) for details.
8 Reenable each card. Replace the voice card, if necessary.
