ATM Board Framer Loop-Around Test (#1260)
This test is destructive.
This test verifies the board's circuit (Time Division Multiplexing) and packet paths using an
on-board, dummy virtual circuit. Before running the test, you must:
● busyout the ATM-TRK circuit pack (busyout board location) and
● switch synchronization (change synchronization) from the ATM-TRK circuit pack
If the ATM-TRK circuit pack is supplying synchronization, the test aborts.
The test sends a digital counter from one of the Tone Generators via one of the TDM bus time
slots. The ATM framer interface converts this digital counter to ATM cells and loops them back
internally. The ATM-TRK circuit pack converts the cells back to a digital counter and sends it to
the tone receiver for verification. If the circuit pack passes the circuit check, the software
checks the packet path by sending a packet from the packet-interface circuit pack to the
ATM-TRK circuit pack via the ATM protocol stack.

Description / Recommendation
1002 ABRT Time slots could not be allocated. Traffic could be heavy or time slots could
be out-of-service.
1. Run display errors, and perform repairs associated with
TDM-BUS errors.
2. Retry the command up to 3 times at 1-minute intervals.
1003 ABRT Tone receiver could not be allocated.
1. Run display errors, and perform the repairs associated with
TTR-LEV and TONE-PT errors.
The test cannot run unless there is at least one Tone Detector available
in the PN that holds the ATM-TRK circuit pack.
2. Retry the command up to 3 times at 1-minute intervals.
1015 ABRT ATM-TRK circuit pack not busied out
1. Busyout the ATM circuit pack.
2. Rerun the command.
