Troubleshooting Modem-Pool Symptoms
Certain customer-reported troubles may provide important information for
troubleshooting Modem Pool problems. For example, if the customer tries to
make a data call requiring a Modem Pool conversion resource, and the Modem
Pool and Data Module speeds or other options do not match, they may receive a
"CHECK OPTIONS" error message on the terminal. In this case, check the
Modem Pool administration and Data Module option settings. If the Modem Pool
is a Combined type, check also the option settings on the external Modem and
Data Module, and cabling and connections between the Digital Line port, Data
Module, Analog Line port, and Modem.
Testing Modem Pools
There are three types of commands that can be used to test Modem Pool circuits:
test port, test modem-pool #, and test board. The test port command is
generally the first test to run after the Error Log is evaluated and an entry is found
for a Modem Pool port. The test modem-pool # command runs the same tests
as the test port short command performed on a Modem Pool port. However, the
test modem-pool # command can automatically test every port in the Modem
Pool group number specified in #. The test board command performs the same
tests as test port and test modem-pool # plus additional tests for circuits
common to the entire circuit pack. See
page 8-1374
(#50, #52, and #53).
If the Modem Pool port or group being tested with test modem-pool # contains
Combined Modem Pools, the ports on the associated Analog Line circuit pack and
the TN754 Digital Line circuit pack are tested as a group. Note, however, that
Combined Modem Pools are not tested with the tests described in this section and
the repair information related to Tests #96, 97, 98, and 99 is not applicable. The
Analog port of the Combined Modem port is tested with Analog port tests, and the
Digital port of the Combined Modem port is tested with TDMODULE/PDMODULE
tests. Therefore, use the repair procedures outlined in the ANL-LINE, ANL-16-L,
ANL-NE-L, and TDMODULE/PDMODULE Maintenance documentation when
interpreting the results of the execution of the test modem-pool # command on
Combined Modem Pools.
