VAL-PT (Voice Announcements over LAN Packet/Port)
Issue 1 June 2005 2507
SCOTCH Synchronous Loop-Around Test (#1275)
This test is destructive.
Note:
Note: G700: On the G700, this test aborts with Error Code 1412.
This test verifies the circuit in the data path of a VAL announcement port call. This test fails if the
data transmitted on the port does not match the data received in the loop-around mode. Failure
of this test indicates a port hardware fault on the circuit pack.
This test aborts if calls are using the port, or if the VAL link associated with the port is
connected. To avoid this, at the SAT type busyout port location, which tears down every
call and link using the port.
FAIL Received tones do not match transmitted tones.
1. Retry command at 1-minute intervals up to 3 times.
2. If the problem persists, see TDM-BUS (TDM Bus)
on page 2237,
TONE-PT (Tone Generator)
on page 2353, and Tone Receiver repair
procedures.
3. If the problem persists, reset the board (busyout board location,
reset board location, and release board location).
Repeat the test.
4. If the problem persists, replace the circuit pack.
PASS Port connections across the TDM bus function properly.

1000 ABRT The port is in use.
1. Retry the command when the port is idle. You can force the port to the
idle state with busyout port location.
Note: This command is destructive, tearing down every call and link
using the port.
