FE[11:0]

FE[11:0] represents the number of PLCP framing pattern octet errors and path overhead

identification octet errors that have been detected since the last time the framing error event

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 Framing Error Event 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. Framing error

errors are not accumulated when the S/UNI-JET has declared a PLCP LOF defect state.
