Default
Bit No.
Type
This bit is valid when SF, ESF or SLC-96 frame is in synchronization.
= 0: Disable the signaling snapshot.
= 1: Enable the signaling snapshot. That is, the signaling bits of the first frame are locked and output on the RSIGn/MRSIGA(MRSIGB) pin as the
= 0: The replacement is performed on a per-channel basis by setting the STRKEN bit (b4, T1/J1-ID-41~58H) in the corresponding channel.
= 1: The signaling bits (ABCD) of all channels are replaced by the signaling trunk conditioning code in the A,B,C,D bits (b3~0, T1/J1-ID-41~58H).
These bits select the replacement of all the channels.

The replacement is performed on a per-channel basis by setting the SUBST[2:0] bits (b7~5, T1/J1-ID-01~18H) in the corresponding channel.
The data of all channels is replaced by the data trunk code set in the DTRK[7:0] bits (b7~0, T1/J1-ID-21~38H).
The data of all channels is replaced by the A-Law digital milliwatt pattern.
The data of all channels is replaced by the µ-Law digital milliwatt pattern.
