236 IBM Voice Over Frame Relay Perform Guide
PROBLEM: Calls are not being processed between two nodes, and
there are no alarms.
Cause: Two circuit groups are connected to a single node.
Response:UsetheSHOW CONFIG CIRCUIT_GROUP ALL command to find
out if any nodes are connected to two or more circuit
groups. Combine the problem circuit groups into one circuit
group.
PROBLEM: Translation rules are mysteriously created when a circuit
group is created.
Cause: If a circuit group is deleted that had a translation rule
assigned, the same translation rule number will be
reassigned when the circuit group number is recreated.
Response:UsetheCALL_PRO TRANS <rule#> <case#> DELETE or MODIFY
command to remove or modify the translation rule.
G.3 Console Port
This section presents possible responses to problems associated with the IBM
9783 console port.
PROBLEM: Cannot communicate with the console port.
Cause: Configuration problem.
Response: Verify the following factors:
The baud rate, stop bits, character length, and parity bits
of async data.
The RS-232/RS-485 switch on the IBM 9783 unit rear
panel.
The cable pinout.
Disable XON/XOFF or modem signal flow control
If connected to a PC, loop pins 2 and 3 at the end of the
DB9 cable (from PC). Characters that are typed at the
keyboard should echo back to the screen. If characters
appear on screen, the PC port is transmitting and receiving
properly.
PROBLEM: Cannot download to the console port.
Cause: Either the Loader configuration is incorrect (filename, unit
ID, serial port number, or serial port rate) or the unit and
the Loader have lost synchronization.
