UDS1-BD (UDS1 Interface Circuit Pack)
Echo Cancellation is no longer being supplied by the board. Clear the alarm using the
following commands: busyout board location, test board location long, and
release board location. If Test #1420 (Echo Canceller test) fails, replace the circuit
pack.
t. Error Type 1537: LAN Bus Timeout Error. This error occurs when the circuit pack transmits
too many bytes on the LAN bus for a single frame. This condition may be caused by an
on-board fault or by faulty data received on one of the circuit pack’s external ports. If any of
the ports on this circuit pack are alarmed, refer to the repair procedures for those
Maintenance Objects.
If the error occurs three times within 10 minutes, the board is isolated from the Packet bus
and the board is alarmed. To clear the alarm and restore the board to the Packet bus, use
busyout board location, reset board location, test board location
long, and release board location.
If the problem persists, and there are no PKT-BUS alarms or port alarms, then replace the
circuit pack.
u. Error Type 1538: the hyperactive circuit pack is out-of-service and may exhibit one or more
of the following symptoms:
● The common circuit pack level tests such as Test #50 and/or Test #52 abort with Error
Code 2000.
● The tests run on the ports of this circuit pack return a NO-BOARD result.
● A busyout/release of the circuit pack has no effect on test results.
● A list configuration command shows that the circuit pack and ports are
properly installed.
The circuit pack is isolated from the system and every trunk or port on this circuit pack is
placed into the out-of-service state. The system will try to restore the circuit pack within
20-30 minutes. When no faults are detected for 20-30 minutes, the UDS1 Interface circuit
pack is restored to normal operation. Every trunk or port of the UDS1 Interface circuit pack
is then returned to the in-service state.
If the board is not restored to normal operation or the error recurs after the board was
restored to normal operation, escalate the problem.
v. Error Types 3073 to 3160: for releases of G3V4 and higher, Error Type 3073 shows that
this board is receiving slips. The Aux Data contains the last slip count reported.
w. Error Type 3330: LAN critical error. A critical failure has been detected in the Packet bus
interface of the circuit pack. This failure may be due to an on-board fault or a Packet bus
fault. If the Packet bus is alarmed, see PKT-INT (Packet Interface) for recommended repair
procedures.
This error isolates the board from the Packet bus and raises an alarm. If the Packet bus is
not alarmed, enter busyout board location, reset board location, test
board location, and release board location. This should clear the alarm and
restore the board to the Packet bus.
If the problem persists, and there are no PKT-BUS alarms, then replace the circuit pack.
