GSUBST[2:0]
Bit Name
Bit Name
This bit is valid when the Signaling Multi-frame is generated.
= 0: Disable the signaling snapshot.
= 1: Enable the signaling snapshot. That is, the signaling bits of the first Basic frame are locked and input on the TSIGn/MTSIGA(MTSIGB) pin as
the signaling bits of the current whole Signaling Multi-frame.
= 0: The replacement is performed on a per-timeslot basis by setting the STRKEN bit (b4, E1-ID-41~4FH & 51~5FH) in the corresponding timeslot.
= 1: The signaling bits (ABCD) of all timeslots are replaced by the signaling trunk conditioning code in the A,B,C,D bits (b3~0, E1-ID-41~4FH &
51~5FH).
These bits select the replacement of all the channels.
= 0: Disable all the functions in the Transmit Payload Control.
= 1: Enable all the functions in the Transmit Payload Control.

The replacement is performed on a per-timeslot basis by setting the SUBST[2:0] bits (b7~5, E1-ID-00~1FH) in the corresponding timeslot.
The data of all timeslots is replaced by the data trunk code set in the DTRK[7:0] bits (b7~0, E1-ID-20~3FH).
The data of all timeslots is replaced by the A-Law digital milliwatt pattern.
The data of all timeslots is replaced by the µ-Law digital milliwatt pattern.
The data of all timeslots is replaced by the payload loopback code extracted from the Elastic Store Buffer in the receive path.
