ALARM COUNTERS
The three onboard alarm event counters allow the transceiver to monitor and record error events without
processor intervention on each event occurrence. All of these counters are presettable by the user
establishing an event count interrupt threshold. As each counter saturates, the next error event occurrence
will set a bit in the RSR and generate an interrupt unless masked. The user may read these registers at any
time; in many systems, the host will periodically poll these registers to establish link error rate
performance.
OOF EVENTS AND ERRORED
SUPERFRAMES
Out of frame is declared when at least two of four (or five) consecutive framing bits are in error. FT bits
are tested for OOF occurrence in 193S; the FPS bits are tested in 193E. OOF events are recorded by the
4-bit OOF counter in the error counter register. In the 193E framing mode, the OOF event is logically
OR’ed with an on-chip generated CRC checksum. This event, known as errored superframe, is recorded
by the 4-bit ESF error counter in the error count register. In the 193S framing mode, the 4-bit ESF error
counter records individual FT and FS errors when RCR.3=1 or FT errors only when RCR.3=0.
