ALARM OUTPUTS
The transceiver also provides direct alarm outputs for applications when additional decoding and
demuxing are required to supplement the onboard alarm logic.
RLOS OUTPUT
The receive loss of sync output indicates the status of the receiver synchronizer circuitry; when high, an
off-line resynchronization is in progress and a high-low transition indicates that resync is complete. The
RLOS bit (RSR1.3) is a latched version of the RLOS output. If the auto-resync mode is selected (RCR1.1
= 0), RLOS is a real-time indication of a carrier loss or OOF event occurrence.
RYEL OUTPUT
The yellow alarm output transitions high when a yellow alarm is detected. A high-low transition indicates
the alarm condition has been cleared. The RYEL bit (RSR1.4) is a latched version of the RYEL output.
RBV OUTPUT
The bipolar violation output transitions high when the accused bit emerges at RSER. RBV goes low at the
next bit time if no additional violations are detected.
RFER OUTPUT
The receive frame error output transitions high at the F-bit time and is held high for 2 bit periods when a
frame bit error occurs. In 193S, framing FT and FS patterns are tested. The FPS pattern is tested in 193E
framing.
Additionally, in 193E framing, RFER reports CRC6 code word errors by a low-high-low
transition (1 bit period-wide) one-half RCLK period before a low-high transition on RMSYNC (see
Figure 17).
RESET
A high-low transition on RST clears all registers and forces an immediate resync when RST returns high.
RST
must be held low on system power-up to insure proper initialization of the counters and registers.
Following reset, the host processor should restore all control modes by writing appropriate registers with
control data.
