Transmit Loop Activate Code Length. These 2 bits define the length of the transmit loop up
code.
00-Code length is 5 bits
01-Code length is 6 or 3 bits
10-Code length is 7 bits
11-Code length is 8 or 4 bits
Note: if 3 bit code or 4 bit code is required the bits have to be repeated in TXLDC7-0.
For instance if the code 1011 is desired, the TXLAC has to be set to 10111011 and the length
TXLACL to 11.
Transmit Loop Activate Code. This byte specifies the inband loopup code to be transmitted.
The default values are the T1.403 values for Loop Activate Code.

Transmit Loop Deactivate Code Length. These 2 bits define the length of the transmit
loop down code.
00-Code length is 5 bits
01-Code length is 6 or 3 bits
10-Code length is 7 bits
11-Code length is 8 or 4 bits
Note if 3 bit code or 4 bit code is required the bits have to be repeated in the TXLDC7-0. For
instance if the code 1011 is desired, the TXLDC has to be set to 10111011 and TxDLCL to 11
Transmit Loop Deactivate Code. This byte specifies the inband loopdown code to be
transmitted. If 001 is to be transmitted as a loopdown code; the register has to programmed
to a value of XX001001and the length (TXLDL has to be 01).The default values are the
T1.403 values for Loop Deactivate Code.
