j. Error Type 2305 with Aux Data 118—Indicates that the EI circuit pack has
detected slips on the incoming fiber data stream. That is, an PN in a Direct
Connect configuration, or an PN and a Switch Node in a Center Stage
Switch configuration, are not synchronized.
1. Enter display errors and follow the repair procedures for non-slip
errors against any SYNC, TDM-CLK, TONE-BD, DS1 CONV-BD,
EXP-INTF, SNC-BD, and SNI-BD. Non-slip errors are those not
listed below:
2. For slip errors, see ‘‘SYNC (Port-Network Synchronization)’’ on
page 8-1509 .
Error Type 2306—Indicates on-board failures related to system timing and
synchronization. Perform the
‘‘Fault Isolation for Fiber Links’’ described in
Chapter 4, ‘‘Alarms, Errors, and Troubleshooting’’ .
k. Error Type 2561—Indicates an on-board failure of EI circuitry related to
handling packet data from the fiber interface and from the packet-bus
interface.
1. If this error has generated a minor alarm, the EI circuit pack should
be replaced.
l. Error Type 2817—Indicates an on-board failure of EI circuitry related to
transmission of data to the fiber interface.
1. If this error has generated a minor alarm, the EI circuit pack or
transceiver should be replaced.
m. Perform the following steps for error type 3073:
1. Execute the display errors command and resolve any errors on the
following: PKT-BUS, PKT-INT, PDATA-BD, PGATE-BD, BRI-BD,
BRI-PT, BRI-SET/ASAI, UDS1-BD.
2. Enter the test board UUCSS r3 command for this circuit pack. If
this error continues to appear, replace the EI circuit pack.
