9.3 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 will increment once each time the received E–bit is set
to zero. 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 will continue to count if loss of
multiframe sync occurs at the CAS level.
Alternately, this counter will count 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 may be framed, unframed or in any time slot. See section 11 for more details.
