555-233-123 10-1848 Issue 4 May 2002
If the UDS1 board detects only one of these hardware problems, then the
error will disappear when none of these faults are detected for 10 minutes.
If the same Aux Data value is logged more than once in a 24 hour period,
the circuit pack should be replaced.
g. Error Type 514 — LAN External RAM Error. This error occurs when there
is a hardware fault in the PPE external RAM. The RAM is used for
message buffering to and from the Packet Bus. This error should not occur
frequently. If it does (10 times within 30 minutes), the circuit pack should be
replaced.
h. Error Type 769 —Transmit FIFO Underflow Error. This error occurs when
the circuit pack cannot find the “end of frame” bit when transmitting a frame
to the Packet Bus. An alarm is raised if this error occurs three times within
10 minutes. Clear the alarm using the following commands: busyout
board UUCSS, reset board UUCSS, test board UUCSS long, release
board UUCSS. If the error recurs within 10 minutes, replace the circuit
pack.
i. Error Type 770 — Unable to Write LAN Translation RAM Error. This error
occurs when a call is aborted because there are no available translation
RAM locations for the call connection attempt. An alarm is raised if this
error occurs two times within 10 minutes. Clear the alarm using the
following commands: busyout board UUCSS, reset board UUCSS, test
board UUCSS long, release board UUCSS. If the error recurs within 10
minutes, replace the circuit pack.
j. Error Type 1300 — CSU Module/T1 Sync Splitter missing or E1
Synchronization Splitter (E1SS) missing.
CSU Module/T1 Sync Splitter missing: The
Near-End CSU Type
field
on the add ds1 form has been administered as
integrated
but the
120A1 CSU Module or the 401A T1 Sync Splitter is not physically
connected (or is improperly connected) to the UDS1 board on the back of
the port carrier.
If using the 120A1 CSU Module or the 401A T1 Sync Splitter, plug (or
replug) the CSU Module/T1 Sync Splitter into the UDS1 circuit pack’s
connector on the I/O connector panel on back of the carrier. Otherwise,
change the
Near-End CSU Type
field using the change ds1 form to
other
.
If this error remains after plugging the CSU Module/T1 Sync Splitter into
the board’s connector, there could be a problem with the I/O connector
panel.
E1 Synchronization Splitter missing: The
E1 Sync-Splitter?
field
on the add ds1 form has been administered as
y,
but the 402A or 403A
E1 Synchronization Splitter is not physically connected (or is improperly
connected) to the UDS1 board on the back of the port carrier.
