B1E[15:0]

B1E[15:0] represents the number of PLCP bit interleaved parity (BIP) errors that have been

detected since the last time the B1 error counter was polled. The counter (and all other

counters in the CPPM) is polled by writing to any of the CPPM register addresses (322H –

32FH). Such a write transfers the internally accumulated count to the B1 Error Count

Registers and simultaneously resets the internal counter to begin a new cycle of error

accumulation. This transfer occurs within 67 RCLK periods (1.5 µs for the DS3 bit rate;

1.95µs for the E3 bit rate) of the write. The transfer and reset is carried out in a manner that

coincident events are not lost. B1 errors are not accumulated when the S/UNI-JET has

declared a PLCP LOF defect state.
