Bit Name
Default
Bit No.
Type
This bit is valid in 8-bit-based mode or in 7-bit-based mode selected by the PRBSMODE[1:0] bits (b3~2, T1/J1-0C7H).
= 0: Disable the data in the corresponding channel to be tested by the PRBS Generator/Detector.
= 1: Enable the data in the corresponding channel to be extracted to the PRBS Generator/Detector for test (when the PRBSDIR bit (b1, T1/J1-
All the channels that are extracted to the PRBS Generator/Detector are concatenated and treated as a continuous stream in which pseudo ran-
= 0: The signaling insertion is not allowed.

= 0: No operation.
= 1: The data of the corresponding channel is replaced by the signaling trunk code set in the A, B, C, D bits (b3~0, T1/J1-ID-41~58H).
These bits are the signaling trunk code that can replace the signaling bits of the channel selected by the GSTRKEN bit (b6, T1/J1-0CBH) or the
