B8ZS is turned on. This counter is incremented once if 16 or more zeros are detected if B8ZS
is turned off. This counter counts groups of 8 or more or 16 or more zeros separated by ones.
CRC-6 Error Counter Bits 15 to Zero. These are the 16 bits of the CRC-6 error counter. This
is only relevant in the ESF Mode. This counter increments for every CRC-6 error.

frame synchronization. Hence if you loss sync, gain sync and loss it again the counter will
have a value of 2.
resynchronization is done which results in a shift in the frame alignment position.
BPV Counter. 16 bit counter that is incremented for every bipolar violation error received.
Framing Bit Error Counter. This 16 bit counter will be incremented for each error in the
received framing pattern. In ESF mode the ESF framing bits are monitored. In D4 mode the
counter reflects the combination of Ft and Fs errors. The count is only active if the Framer
is in synchronization.
