Data Module Internal Looparound Test (#175)
Data Module Internal Looparound Test (#175)
2500 ABORT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
2000 FAIL No response received within the time allowed.
1. If the test fails again, replace the Data Line circuit pack.
FAIL The data received did not match the data sent. This indicates a fault
somewhere in the transmit/receive path to the TDM Bus, which will
probably result in data corruption over this port. This test may fail if the
Maintenance/Test digital port used by the test is not functioning properly.
1. Resolve any M/T-DIG (Maintenance/Test Digital Port) errors.
2. Repeat Test #171.
3. If the test fails again, replace the data line circuit pack.
PASS The port can correctly transmit/receive data. Investigate user-reported
troubles on this port using other port tests by examining the ADU, external
wiring, and customer equipment.
4 of 4
This test verifies that a data message can be sent from the switch, through the building wiring,
through an internal looparound path in the data module, and back to the switch. This path is
illustrated below.
For this test to run, the Remote Looparound Test field on the Data Module administration
screen must be set to y, indicating that the data module endpoint supports the test.
This test runs on PDMODULE (Processor Data Module) and TDMODULE (Trunk Data Module).
