Maintenance-Object Repair Procedures
The Inter-PN Index contains six fields (XX.XX.XX.XX.XX.XX), and the Inter-SN
Index has two (XX.XX). The Inter-PN Index reports faults in connectivity between
port networks and supersedes the Inter-SN Index, which reports faults in
connectivity between switch nodes. (The Inter-SN Index is only meaningful for
systems with a center stage switch having two switch nodes, each of which is
duplicated).
The meaning of each fault class field is given in the following table. A zero entry
indicates that there are no such faults reported. Higher numbers indicate
increasing number of faults. All zeros indicates perfect state of health. Unless the
PNCs are locked, the active PNC's state of health should always be equal to or
better than the standby's. (Otherwise, the system would perform a spontaneous
interchange.)
After a PNC-related alarm is cleared, the system performs a partial refresh of the
standby PNC. The corresponding fault class field is not updated to reflect the
improved state of health until the refresh is done. The state of health indexes will
not agree with the current alarm status during this period.

1. BFDLs only exist in Port networks that have an IPSI. Port networks that do not have an IPSI will
have the EI as Archangel and no BFDL faults.
