TEST:
This bit is valid in 8-bit-based mode or in 7-bit-based mode selected by the PRBSMODE[1:0] bits (b3~2, E1-0C7H,...).
= 0: Disable the data in the corresponding timeslot to be tested by the PRBS Generator/Detector.
= 1: Enable the data in the corresponding timeslot to be extracted to the PRBS Generator/Detector for test (when the PRBSDIR bit (b1, E1-
0C7H,...) is ‘0’); or enable the test pattern from the PRBS Generator/Detector to replace the data in the corresponding timeslot for test (when the PRB-
SDIR bit (b1, E1-0C7H,...) is ‘1’). In 8-bit-based mode, the data refers to all 8 bits. In 7-bit-based mode, the data refers to the 7 MSB.
All the timeslots that are extracted to the PRBS Generator/Detector are concatenated and treated as a continuous stream in which pseudo ran-
dom are searched for. Similarly, all the timeslots set to be replaced with the PRBS Generator/Detector test pattern data are concatenated replaced by
the PRBS.
STRKEN:
= 0: No operation.
= 1: The data of the corresponding timeslot is replaced by the signaling trunk code set in the A, B, C, D bits (b3~0, E1-ID-41~4FH & 51~5FH).
A, B, C, D:
These bits are the signaling trunk codes that can replace the signaling bits of the timeslot selected by the GSTRKEN bit (b6, E1-0D0H,...) or the
STRKEN bit (b4, E1-ID-41~4FH & 51~5FH).
