NAME AND DESCRIPTION
RCS
RCR2.7
Receive Code Select. See Section 11 for more details.
0 = idle code (7F Hex)
1 = digital milliwatt code (1E/0B/0B/1E/9E/8B/8B/9E Hex)
RZBTSI
RCR2.6
Receive Side ZBTSI Enable.
0 = ZBTSI disabled
1 = ZBTSI enabled
RSDW
RCR2.5
RSYNC Double–Wide. (note: this bit must be set to zero when
RCR2.4 = 1 or when RCR2.3 = 1)
0 = do not pulse double wide in signaling frames
1 = do pulse double wide in signaling frames
RSM
RCR2.4
RSYNC Mode Select. (A Don’t Care if RSYNC is programmed as
an input)
0 = frame mode (see the timing in Section 20)
1 = multiframe mode (see the timing in Section 20)
RSIO
RCR2.3
RSYNC I/O Select. (note: this bit must be set to zero when CCR1.2
= 0)
0 = RSYNC is an output
1 = RSYNC is an input (only valid if elastic store enabled)
RD4YM
RCR2.2
Receive Side D4 Yellow Alarm Select.
0 = zeros in bit 2 of all channels
1 = a one in the S–bit position of frame 12
FSBE
RCR2.1
PCVCR Fs–Bit Error Report Enable.
0 = do not report bit errors in Fs–bit position; only Ft bit position
1 = report bit errors in Fs–bit position as well as Ft bit position
MOSCRF
RCR2.0
Multiframe Out of Sync Count Register Function Select.
0 = count errors in the framing bit position
1 = count the number of multiframes out of sync
