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.
3 Number of PNs with BFDL (Bearer Fault
Detection Link) faults
SYS-LINK
FC_HW 4 Number of PNs affected by hardware
faults in a link having an EI as an
endpoint (Endpoints can be determined
with list fiber-link.)
