PI-SCI (System Communication Interface)
Issue 4 May 2002

555-233-123
h. An audit of the firmware failed. If BX.25 and ISDN links are still up, no
action is needed. If Processor Interface circuit pack is reset continuously,
recover as in Note (b).
i. Error while communicating with TN765 Processor Interface circuit pack.
See Note (b) for recovery. System software problem internal to the process
that monitors Processor Interface link activity. Escalate the problem if error
causes the Processor Interface to be reset (loss of service is noticed).
j. This error indicates that the TN765 Processor Interface circuit pack did not
clear up the overload condition within one minute of logging the initial 2817
error (overload detected). The circuit pack was reset and all Processor
Interface links on that circuit pack were also reset.
Short and Long Test Sequences
The SCI and Processor Interface circuit pack are both tested via the same system
technician command. The system technician command is test interface PCS l or
sh where PCS is an active Processor Interface circuit pack.
!
WARNING:
The “test interface long” command resets the PI-BD and causes all
ISDN-PRI and BX.25 links to come down.
For information about testing the Standby Processor Interface circuit pack, see
PI-BD Maintenance documentation. If the Active Processor Interface has no
enabled links (see Communication-Interface Links Form in
‘‘Maintenance Commands and Trouble-Clearing Aids’’
, only XXX-BD (Common
Port Circuit Pack) tests execute.
System Technician Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the SCI Start Test,
for example, you may also clear errors generated from other tests in the testing
sequence.
a. For information about these tests, refer to the XXX-BD (Common Port
Circuit Pack) Maintenance documentation. These tests are run on the
PI-BD (Processor Interface Circuit Pack) Maintenance object.
