Receiver Section ON - Channel 2
This READ/WRITE bit-field is used to either turn on or turn off the
Receive Section of Channel 2. If the user turns on the Receive Sec-
tion, then Channel 2 will begin to receive the incoming DS3, E3 or
STS-1 data-stream via the RTIP_2 and RRING_2 input pins.
Conversely, if the user turns off the Receive Section, then the entire
Receive Section (e.g., AGC and Receive Equalizer Block, Clock
Recovery PLL, etc) will be powered down.
0 - Shuts off the Receive Section of Channel 2.
1 - Turns on the Receive Section of Channel 2.
