Receive Monitor Mode Enable - Channel_n:
This READ/WRITE bit-field is used to configure the Receive Section of
Channel_n to operate in the Receive Monitor Mode.
If the user configures the Receive Section to operate in the Receive Monitor
Mode, then it will be able to receive a nominal DSX-3/STSX-1 signal that
has been attenuated by 20dB of flat loss along with 6dB of cable loss, in an
error-free manner. However, internal LOS circuitry is suppressed and LOS
will never assert nor LOS be declared when operating under this mode.
0 - Configures the corresponding channel to operate in the Normal Mode.
1 - Configure the corresponding channel to operate in the Receive Monitor
Mode.
Receive Equalizer Enable - Channel_n:
This READ/WRITE register bit is used to enable or disable the Receive
Equalizer block within the Receive Section of Channel_n, as listed below.
0 - Disables the Receive Equalizer within the corresponding channel.
1 - Enables the Receive Equalizer within the corresponding channel.
