13.4 E-Bit Counter Register (EBCR)

This counter is only available in the E1 mode. EBCR1 (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 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.
