ALARM COUNTERS
The three onboard alarm event counters allow the trans-
ceiver to monitor and record error events without pro-
cessor intervention on each event occurrence. All of
these counters are presettable by the user establishing
an event count interrupt threshold. As each counter sat-
urates, 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 sys-
tems, the host will periodically poll these registers to es-
tablish 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. F
T
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 er-
ror counter in the error count register. In the 193S fram-
ing mode, the 4-bit ESF error counter records individual
F
T
and F
S
errors when RCR.3=1 or F
T
errors only when
RCR.3=0.
