Receive Section ON - Channel n
This READ/WRITE bit-field is used to turn on or turn off the Receiver associated with
Channel n on a per channel basis. If the user turns on the Receiver, then Channel n
will Receive DS3, E3 or STS-1 pulses on the line via the RTIP_n and RRING_ n input
pins.
Conversely, if the user turns off the Receiver Driver (for channel n), the RTIP_n and
RRING_n input pins will be in a high impedance state.
0 - Shuts off the Receive Driver associated with Channel n and puts the RTIP_n and
RRING_ n input pins in a high impedance state.
1 - Turns on the Receive Driver associated with Channel n.
