Bit No.
Type
This bit is valid when Signaling Multi-frame is in synchronization.
= 0: Disable the signaling snapshot.
= 1: Enable the signaling snapshot. That is, the signaling bits of the first Basic frame are locked and output on the RSIGn/MRSIG pin as the sig-

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.
