18.10 Receive Ring Control Port Timing (RRCP)
RRCP serially outputs all the section, line, and path defects detected in the receive data stream.
Sampling RRCPFP high with RRCPCLK, identifies the OOF defect on RRCPDAT. Path
information is updated two times during a single frame period of 125 s as shown in Figure 44.
Four RRCPDAT are used to carry the section/line and path alarms for the 192 paths when
processing an STS-192/STM-64 stream or for the four groups of 48 paths when processing four
STS-48/STM-16 streams. In both modes, RRCPDAT[N] extracts the 12 path alarms from
slice#N,1 followed by the 12 path alarms from slice#N,2, then slice#N,3 and finally the 12 path
alarms from slice#N,4.
Also shown is the receive path alarm (RALM) functional timings. RALM serially outputs the
“ORing” of the enabled path defects. The same figure shows the STS-1/STM-0 time slots
assignment on RALM. Each STS-1/STM-0 time slot is either high or low for 54 consecutive
RRCPCLK clock cycles.
