Troubleshooting Modem-Pool Symptoms
Certain customer-reported troubles may provide imp ortant information for
troubleshooting Modem Pool prob lems. For example, if the customer tries to
make a data call requiring a Modem Pool conversion resource, and the Modem
Pool and Data Module speed s or other options do not ma tch, they may receive a
‘‘CHECK OPTIONS’’ error message on the terminal. In this case, check the
Modem Pool administration and Data Mod ule option settings. If the Mod em Pool
is a Combined type, c heck also the option setting s on the external Modem and
Data Module, and cab ling and connec tions between the Digital Line p ort, Data
Module, Analog Line por t, and Modem.
Testing Modem-Pools
There are three types of commands that c an be used to test Mod em Pool circuits:
test port, test modem-pool #, and test board. The test port c ommand 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 per formed on a Modem Pool port. However, the
test modem-pool # command can automatic ally test all ports in the Modem Pool
group number sp ecified in #. The test board command performs the same tests
as test port and test modem-pool # plus add itional tests for circuits comm on to
the en tire c ircu it p ack. Refer to the "XXX-B D (Com mon Por t Circ uit Pa ck) " secti on
for information on additional tests p erformed with test b oard (#50, #52, and #53).
If the Modem Pool port or group being tested with test modem-pool # c ontains
Combined Modem Pools, the ports on the associated Analog Line circuit pack
and the TN754 Digital Line circui t pack are tested as a g roup. Note, however,
that Combined Modem Pools are not tested with the tests described in this
section and the repair infor mation 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 Dig ital 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 interp reting the results of the execution of the test
modem-pool # command on Combined Modem Pools.
