Programming Information
IDT82P2288
Bit Name
This bit is valid in SF, ESF or SLC-96 format.
= 0: Disable the signaling snapshot.
= 1: Enable the signaling snapshot. That is, the signaling bits of the first frame are locked and input on the TSIGn/MTSIGA(MTSIGB) pin as the
signaling bits of the current whole SF, ESF or SLC-96 frame.
= 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 one type of Zero Code Suppression. (Bit 1 is the MSB in the following table).
These bits select the replacement of all the channels.
Default
Bit No.

No Zero Code Suppression.
GTE Zero Code Suppression. Bit 8 of an all-zero channel is replaced by a ‘1’, except in signaling frames where Bit 7 is
forced to be a ‘1’.
Jammed Bit 8 Zero Code Suppression. Bit 8 of all channels are replaced by a ‘1’.
Bell Zero Code Suppression. Bit 7 of an all-zero channel is replaced by a ‘1’.
DDS Zero Code Suppression. An all-zero channel is replaced with ‘10011000’.
Reserved.
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.
The data of all channels is replaced by the payload loopback code extracted from the Elastic Store Buffer in the receive
path.
