The indirect registers of TPLC addressed from 41H to 4FH and from 51H to 5FH are the Signaling Trunk Conditioning Code Registers for TS1 to
When the GSUBST[2:0] bits(b2~0, E1-0CBH,...) are ‘000’, these bits select the replacement on a per-channel basis.
These three bits select how to invert the bits in the corresponding channel.

The data of the corresponding timeslot is replaced by the data trunk code set in the DTRK[7:0] bits (b7~0, T1/J1-ID-21~38H).
The data of the corresponding timeslot is replaced by the A-Law digital milliwatt pattern.
The data of the corresponding timeslot is replaced by the µ-Law digital milliwatt pattern.
The data of the corresponding timeslot is replaced by the payload loopback code extracted from the Elastic Store Buffer in the receive path.

Invert the even bits (bit 2, 4, 6, 8) of the corresponding channel (bit 1 is the MSB).
Invert the odd bits (bit 3, 5, 7) except the MSB of the corresponding channel (bit 1 is the MSB).
Invert the bits from bit 2 to bit 8 of the corresponding channel (bit 1 is the MSB).
Invert the MSB (bit 1) of the corresponding channel.
Invert the MSB (bit 1) and the even bits (bit 2, 4, 6, 8) of the corresponding channel.
Invert all the odd bits (bit 1, 3, 5, 7) of the corresponding channel (bit 1 is the MSB).
Invert all the bits (bit 1 ~ bit 8) of the corresponding channel (bit 1 is the MSB).
