1. On power-on reset the register is set to “0”.
1. On power-on reset the register is set to “0”.
2. Maximum cable loss at 772 KHz.
3. When reading LEN, bit values appear inverted. “B1” revision silicon will fix this so the bits read back correctly.
1. On power-up all the register bits are set to “0”.
1. On power-up all the register bits are set to “0”. All AIS interrupts are cleared by a single read operation.

The three bit value written to these bits determine the channel to be addressed:
0H = channel 0
1H = channel 1
2H = channel 2
3H = channel 3
Data can be read from (written to) the Pulse Shaping Data Register (PSDAT).
Reserved.
LEN0-2 determine the LXT386 operation mode: T1 or E1. In addition, for T1 operation,
LEN2-0 set the pulse shaping to meet the T1.102 pulse template at the DSX-1 cross-
connect point for various cable lengths:
Reserved.
Setting a bit to “1” tristates the output driver of the corresponding transceiver.
Respective bit(s) are set to “1” every time the receiver detects a AIS condition in
transceivers 3-0.
