10.3 E-Bit/PRBS Bit-Error Counter
E-bit count register 1 (EBCR1) is the most significant word and EBCR2 is the least significant word of a 16-bit
counter that records far-end block errors (FEBE) as reported in the first bit of frames 13 and 15 on E1 lines running
with CRC4 multiframe. These error count registers increment once each time the received E-bit is set to 0. Since
the maximum E-bit count in a one-second period is 1000, this counter cannot saturate. The counter is disabled
during loss of sync at either the FAS or CRC4 level; it continues to count if loss-of-multiframe sync occurs at the
CAS level.
Alternately, this counter counts bit errors in the received PRBS pattern when the receive PRBS function is enabled.
In this mode, the counter is active when the receive PRBS detector can synchronize to the PRBS pattern. This
pattern can be framed, unframed, or in any time slot. See Section 13 for more details.

10.4 FAS Error Counter
FAS count register 1 (FASCR1) is the most significant word and FASCR2 is the least significant word of a 16-bit
counter that records word errors in the FAS in time slot 0. This counter is disabled when RLOS is high. FAS errors
are not counted when the framer is searching for FAS alignment and/or synchronization at either the CAS or CRC4
multiframe level. Since the maximum FAS word error count in a one-second period is 4000, this counter cannot
saturate.
