LEFAS0

Latched Errored FAS Counter. An

8 bit counter that is incremented

once

for

every

receive

frame

alignment signal that contains one

or more errors. These bits are

sampled

every

second

the

internal one second timer.

LBPV8

Latched

BPV

Counter

(most

significant

bits).

The

BPV

counter is incremented once for

every

bipolar

violation

error

received. These bits are sampled

every second by the internal one

second timer.
