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 all ports 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. Refer to the "XXX-BD (Common Port Circuit Pack)" section
for information on additional tests performed with test board (#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.
