MODEM-PT (Modem Pool Port)
Issue 1 June 2005 1689
Test data patterns are transmitted from a Maintenance/Test board’s digital port over network
time slot A through the digital port on the conversion resource, looped around through the
analog port via time slot C back to the Maintenance/Test board’s digital port circuit via time slot
B where the patterns are checked for accuracy. Finally, the test forces a disconnect by breaking
the connection between the Maintenance/Test board’s digital port and the Modem Pool port
(time slot A) and verifying that the Maintenance/Test board’s digital port and Modem Pool port
go on-hook within the proper time. This test attempts to allocate a Maintenance/Test board’s
digital port, Modem Pool port, and other internal resources. If any of these allocation attempts
fail, the test cannot be completed, and a specific abort error is reported.

1000 ABRT System resources needed to complete the test could not be allocated for
the digital section of the Modem Pool conversion resource. Ordinarily, this
means the conversion resource or other hardware used during the test
was in use.
1. Wait 1 minute and attempt the test again.
2. If the conversion resource is in use, and it is absolutely necessary to
test it, the call will have to be dropped by issuing busyout port
location against the conversion resource. Run the test again. If the
test passes, release the port.
3. If the same error occurs while the conversion resource is idle,
busyout both Modem Pool conversion resources on the TN758
Pooled Modem circuit pack containing the conversion resource under
test. Rerun the test.
4. If the test continues to abort, replace the Pooled Modem circuit pack
and retest.
