SCOTCH Synchronous Looparound Test (#1275)
This test is destructive.

This test verifies the circuit in the datapath of a ppp call. This test fails if the data

transmitted on the port d oes not match the data received in the looparound

mode. Failure of this test indicates a p ort hardware fault on the circui t pack.

2100 ABORT Could not allocate the necessary system resources to run test.
1. Retry the command at 1-minute intervals, up to 5 times.
FAIL Received tones do not match transmitted tones.
1. Retry command at 1-minute intervals, up to 3 times.
2. If the problem persists, refer to TDM-BUS, Tone Generator, and Tone
Receiver repair proc edures.
3. If the problem persists, replace the circuit p ack.
PASS Port connections across the TDM bus function properly.

Result Description/ Recommendation
1000 ABORT The port is in use or PPP link is connected.
1. Determine when the port is available for testing (status clan-port
UUCSSpp).
2. If necessary, busyout the circuit pack (busyout port UUCSSpp).
3. Retry the test (#1275) when the port is idle.
1002 ABORT No TDM bus timeslots available for the test.
1. Retry the command at 1-minute intervals, up to 5 times.
1963 ABORT Firmware indicates that the port is in use or ppp link is connected.
1. Determine when the port is available for testing (status clan-port
UUCSSpp).
2. If necessary, busyout the circuit pack (busyout port UUCSSpp).
3. Retry the test (#1275) when the port is idle.
