If the UDS1 board detects only one of these hardware problems, then the
error will disappear when none of these faults are d etected for 10 minutes.
If the same Aux Data value is logged more than once in a 24 hour period ,
the circuit pack s hould be replaced .
g. 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 reg ularly. If this error is
seen quite frequently (10 times within 30 minutes), the c ircuit pack should
be replaced.
h. Transmit FIFO Underflow Error. This error occurs when the c ircuit pack
cannot find the "end of frame" bit when transmitting a frame to Packet Bus.
An alarm will be raised if this error oc curs three times within 10 minutes.
Clear the alarm via the following co mmands: busyout board UUCSS,
reset board UUCSS, test board UUCSS long, release board UUCSS. If
the error recurs within 10 minutes, then replace the circuit pack.
i. Unable to Write LAN Translation RAM Error. This error occurs when a c all
is aborted bec ause there are no available translation RAM locations for
the call connection attemp t. An alarm will be raised if this error oc curs two
times within 10 minutes. Clear the alarm via the following commands:
busyout board UUCSS, reset board UUCSS, test board UUCSS long,
release board UUCSS. If the error recurs within 10 minutes, then replac e
the circuit pack.
j. 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 Spliltter is not physically c onnected (or
is improperly connec ted) to the TN464F board on the bac k of the port
carrier.
If using the 120A1 CSU Module or the 401A T1 Sync Spliltter, plu g (or
replug) t he CSU Module/T1 Sync Splitter into the TN464F circuit p ack’s
connector on the I/O conne ctor panel on bac k 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 connec tor, there could be a p roblem 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 physical ly connected (or is imp roperly
connected) to the TN464F board on the back of the port c arrier.
If using the 402A or 403A E1 Synchronization Splitter, plug (or replug) the
E1SS into the TN464F circuit pack’s connector on the I/O conne ctor panel
on back of the carrier. Otherwise, c hange the E1 Sync-Splitter? field
using the change ds1 form to n.
