PRBS Generator/Detector for test in this block.

lowest in priority):
data to be transmitted will be extracted to the PRBS Generator/Detector.
The data to be transmitted can be extracted in unframed mode, in 8-bit-
based mode or in 7-bit-based mode. This selection is made by the PRB-
SMODE[1:0] bits. In unframed mode, all the data stream to be transmit-
ted is extracted and the per-channel/per-TS configuration in the TEST
bit is ignored. In 8-bit-based mode or in 7-bit-based mode, the data will
only be extracted on the channel/timeslot configured by the TEST bit.
Refer to Chapter 3.27.1 PRBS Generator / Detector for details.
pression can be selected to implement to the data of all the channels of
the corresponding link. This function is only supported in T1/J1 mode.
timeslots of the corresponding link will be replaced by the trunk code set
in the DTRK[7:0] bits, the milliwatt pattern defined in Table 36 and
Table 37, or the payload loopback data from the Elastic Store Buffer
(refer to Chapter 3.27.2.2 Payload Loopback). When the GSUBST[2:0]
bits are set to ‘000’, these replacements will be performed on a per-
channel/per-TS basis by setting the SUBST[2:0] bits in the correspond-
ing channel/timeslot.
TSIGn/MTSIG pins (after processed by the signaling trunk conditioning
replacement and/or valid signaling bits selection) can be inserted into its
signaling bit position of the data stream to be transmitted.

channels/timeslots of the corresponding link will be replaced by the sig-
naling trunk conditioning code in the A,B,C,D bits. When the GSTRKEN
bit is ‘0’, the replacement can be performed on a per-channel/per-TS
basis by setting the STRKEN bit in the corresponding channel/timeslot.
by specifying the address in the ADDRESS[6:0] bits. Whether the data is
read from or written into the specified indirect register is determined by
the RWN bit and the data is in the D[7:0] bits. The access status is indi-
cated in the BUSY bit. Refer to Chapter 4.5 Indirect Register Access
Scheme for details about the indirect registers write/read access.
