Transmit Line Build Out Auto Adjustment:
This bit is used to enable or disable the transmit line build out auto
adjustment feature. When the transmitter of the device is sending
AIS condition, the transmit line build out will automatically be adjust
to one setting lower if this feature is enabled. (Please refer to the
EQC[4:0] bits in register 0x0Fn0 for different settings of Transmit
Line Build Out). This feature is designed to for power saving pur-
poses when an AIS signal is being transmitted.
1 - Enables the transmit line build out auto adjustment feature.
0 - Disables the transmit line build out auto adjustment feature.
NOTE: This feature is only available for T1 short haul applications.

Automatic Performance Control/Response Report
These bits automatically generates a summary report of the PMON
status so that it can be inserted into an out going LAPD message.
Automatic performance report can be generated every time these
bits transition from ‘b00’ to ‘b01‘or automatically every one second.
The table below describes the different APCR[1:0] bits settings.
