Silent channels

What to do if calls

have no voice and

produce a SEER

If calls have no voice and the problem produces a SEER,

follow these steps.

Step Action

1 Check the status of the channels by placing a call

and watching the status of the channel on the DSP

Port Status screen. Load Overlay 80 and perform a

trace call on the TN that is under test as outlined in

the

X11 Input/Output Guide

(NTP 553-3001-400).

Note: If the result shows the channel being acquired,

the network loop path from EC 11 to the Meridian 1 is

correct and secure.

If not, check the SEER printout for any messages

related to that channel, and take the appropriate

action for that SEER.

2 Ensure that you have configured Meridian Mail with

valid TNs and secondary DNs by checking the CAT

table. If the TNs or DNs are incorrect for a particular

card, follow these steps:

a. Disable the card using the System Status and

Maintenance function, as described in the

System

Administration Guide

(NTP 555-7001-301).

b. Log in to the TOOLS level. Select the “Modify

hardware” tool and modify the TNs and DNs if

necessary.

c. Change DNs in the CAT table.

d. Perform out-of-service diagnostics and reenable

the card.

Note: TN mapping is required. Use the scheme in

the table “Input scheme for ACD agent TNs” on

page 10-9.

3 a. Disable the voice cards.

b. Reseat the voice cards.

c. Perform out-of-service diagnostics.

d. Reenable the voice cards.
