5. Check capacity and peak bandwidth consumption for the ATM
span.
h. Error Type 771: the ATM switch is sending cells with unknown Virtual
Path-Identifier (VPI) and Virtual Channel-Identifier (VCI) addresses.
1. Make sure that the ATM-TRK circuit-pack address is administered
identically on the ATM switch and the DEFINITY ECS.
i. Error Type 1281: Board major signals error (loss of high-level signal). The
far-end has detected a major problem in transmissions originating from
the ATM-TRK circuit pack. The possible Aux Data values for this software
counter are listed in Table 9-118
.
If Then
The ATM-TRK circuit pack
fails the loopback test.
The problem is in the ATM-TRK circuit
pack. Replace the circuit pack.
The far-end circuit pack or
ATM switch fails the
loopback test.
The problem is in the far-end circuit pack
or ATM switch. Consult the circuit-pack
or ATM switch documentation for advice.
The equipment at each
end of the ATM span
passes the loopback test
The problem is somewhere in the ATM
span. Lack of bandwidth may be forcing
an intermediate ATM switch to drop cells.
If Then
The capacity of the
span is inadequate or
bandwidth consumption
is too high.
Reduce traffic on the G3V4 switch to
ensure that it is using no more that its
subscribed bandwidth.

Description Repair procedure
15 SYSCLOCK failed The board is not locked to the TDM backplane clock signal. This is
probably due to a Tone Clock problem.
1. Check for TDM-BUS or TONE-BD errors in the Error Log.
2. If no other problems are present, reset the circuit pack (reset
board UUCSS)
