Figure 10-68. Modem Pool Conversion Resource Loop Around Test Set-up
Test data patterns are transmitted from the Network Control Channels 1 or 3 over
network time slot A through the digital port, looped around through the analog
port via time slot C back to the Network Control Channel circuit via time slot B
where the patterns are checked for accuracy. Finally, the test forces a
disconnect by breaking the connection between the Data Channel and Modem
Pool Port (time slot A) and verifying that the Data Channel and Modem Pool Port
go on-hook within the proper time.
This test attempts to allocate a Network Control Channel, 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.
