DESCRIPTION
D3, D2,

Transmit
Attenuator
Sets the attenuation level of the transmitted signal in 1
dB steps. The default (D3 - D0 = 0100) is for a transmit
level of -10 dBm0 on the line with the recommended
hybrid transmit gain. The total range is 16 dB.
18 dB receive front end boost is not used.
Boost is in the path. This boost does not change
reference levels. It is used to extend dynamic range by
compensating for internally generated noise when
receiving weak signals. The receive level detect signal
and knowledge of the hybrid and transmit attenuator
setting will determine when boost should be enabled.
Relay driver open.
Open drain driver pulling low.
TXCLK and RXCLK are driven.
TXCLK and RXCLK are tri-stated.
Alternate TX data source (see Special Register).
