ATM Board Framer Looparound Test (#1260)
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 UUCSS
) 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.
Figure 9-202
and Figure 9-203 show a diagrams of this two-part test, substituting
“CES mode” for “PNC mode.”

Result Description/ Recommendation
1002 ABORT Time slots could not be allocated. Traffic may be heavy or time slots may 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 ABORT 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 on
the network that holds the ATM-TRK circuit pack.
2. Retry the command up to 3 times at 1-minute intervals.
1015 ABORT ATM-TRK circuit pack not busied out
1. Busyout the ATM circuit pack.
2. Rerun the command.
