Controls the behavior of Sa4 bits transmitted towards the HDSL link, as follows:
0 = Transparent
1 = From bits buffer 1
Controls the behavior of Sa5 bits transmitted towards the HDSL link, as follows:
0 = Transparent
1 = From bits buffer 0
Controls the behavior of Sa6 bits transmitted towards the HDSL link, as follows:

The Automatic mode operates based on the result of the receiver (PCM to HDSL) CRC
check and E-bits, as follows:
Received E-bits
0 (Error)
0 (Error)
1 (No Error)
1 (No Error)
