RMR1/RMR2/RMR3: RECEIVE MARK REGISTERS (Address=2D to 2F Hex)
(MSB) (LSB)
CH8 CH7 CH6 CH5 CH4 CH3 CH2 CH1
CH16 CH15 CH14 CH13 CH12 CH11 CH10 CH9
CH24 CH23 CH22 CH21 CH20 CH19 CH18 CH17
SYMBOL POSITION NAME AND DESCRIPTION
CH24 RCBR3.7 Receive Channel Blocking Registers.
0 = do not affect the receive data associated with this channel
CH1 RCBR1.0 1 = replace the receive data associated with this channel with either the idle
code or the digital milliwatt code (depends on the RCR2.7 bit)
8.2.2 Per–Channel Code Insertion
The second method involves using the Receive Chan-
nel Control Registers (RCC1/2/3) to determine which of
the 24 T1 channels off of the T1 line and going to the
backplane should be overwritten with the code placed in
the Receive Channel Registers (RC1 to RC24). This
method is more flexible than the first in that it allows a
different 8–bit code to be placed into each of the 24 T1
channels.
RC1 TO RC24: RECEIVE CHANNEL REGISTERS (Address=58 to 5F and 80 to 8F Hex)
(for brevity, only channel one is shown; see Table 1–3 for other register address)
(MSB) (LSB)
C7 C6 C5 C4 C3 C2 C0
SYMBOL POSITION NAME AND DESCRIPTION
C7 RC1.7 MSB of the Code (this bit is sent first to the backplane)
C0 RC1.0 LSB of the Code (this bit is sent last to the backplane)
