Note for BPV and CRC:
Only in-service (restored) ports are sampled; therefore, the BPV or CRC counts
displayed correspond to a particular error rate depending on the number of in-service ports. Find the
BPV count in one of the tables below that is closest to the displayed BPV or CRC count and in the column
which represents the number of ports in service, then follow across to the corresponding error rate. Be-
cause the ports are sampled in turn, there is some amount of settling time for the framing circuit. This
settling time causes an error of ±4% in the specified error rate. The observation interval is 15 minutes.
If an MRC or PSM card has only one port active, no sampling occurs.
