RECEIVE SIGNALING
Robbed bit signaling data is presented at RABCD during each channel time in signaling frames for all 24
incoming channels. Logical combination of clocks RMSYNC, RSIGFR and RSIGSEL allow the user to
identify and extract AB or ABCD signaling data.

193S RECEIVE MULTIFRAME TIMING Figure 14
NOTES:
1. Signaling data is updated during signaling frames on channel boundaries. RABCD is the LSB of each
2. RLINK data (S-bit) is updated one bit time prior to S-bit frames and held for two frames.

NAME AND DESCRIPTION
Receive Mark Registers. Each of these bit positions represents a
DS0 channel in the incoming T1 frame. When set, the
corresponding channel will output codes determined by RCR.4 and
RCR.5.
