238 IBM Voice Over Frame Relay Perform Guide
PROBLEM: There is no data throughput even though there are no
alarms and all DLCIs are active.
Cause: A subDLCI mismatch exists or severe network congestion
is occurring.
Response: Make sure the same subDLCI is connected on both sides
of the DLCI.
Use
SHOW PERFORMANCE FRAME DLCI command to check
FECN, BECN, and DE values. Modify, if necessary, to
reduce congestion.
G.6 Remote Unit Command Channel
This section presents possible responses to problems associated with the IBM
9783 remote unit command channel.
PROBLEM: The remote node is not listed on the SHOW REMOTE
table.
Cause: Because an IBM 9783 unit polls its neighbors every 10
minutes, it can take this long for a remote unit to appear on
the table.
Response: Perform a CHANNEL DISCONNECT on the channel in
question and ensure that LMI is established. If so, perform
a CHANNEL CONNECT. The node should appear within
approximately 30 seconds.
G.7 Translation Rules
This section presents possible responses to general problems associated with
IBM 9783 translation rules.
PROBLEM: Calls are going through on cases 0-6 only; the remaining
rules require the interdigit timeout.
Cause: Only the first seven cases are processed on the voice
card. To match rules beyond 0-6, the interdigit timeout
must be reached, causing the entire dial string to be
transferred to the HSP for further processing.
Response: Reorder or redesign the dial rules to have no more than
seven rules. You can also lower the interdigit timeout value
on the call processing setup, but this can cause the dial
time to end too soon thereby impacting usability.
PROBLEM: Unable to change translation table for a voice port.
Cause: There is no case 0 in a translation rule that is assigned to a
voice port. You cannot assign a different translation table
until case 0 is added to the table that is assigned to the
voice port. The SHOW CONFIG VOICE response shows a
translation number followed by a question mark (?).
Response: Enter a case 0 to the translation table and change the rule
number.
