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
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 test port short performed on a Modem
modem-pool # command runs the same tests as test port short performed on a Modem
Pool port. However, test modem-pool # 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
port and test modem-pool # plus additional tests for circuits common to the entire circuit
pack. See
about 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
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 test modem-pool # on Combined Modem Pools.
