responding HG.
11:8
FRM_R_HGA[3:0]
HG Alignment. Indicates the alignment status for the corre-
sponding HG. A 0 indicates no alignment. A 1 indicates align-
ment for the corresponding group.
7:4 FRM_R_HGRDI[3:0] HG RDI. Indicates the detection of three consecutive zeros in 0000
the Sp bit position of the corresponding HG.
3
FRM_R_TS16A
Time Slot 16 Multiframe Alignment Status. A 0 indicates
that, currently, time slot 16 multiframe alignment is not estab-
lished. A 1 indicates that, currently, time slot 16 multiframe
alignment has been established.
0
2
FRM_R_TS16AIS
RSVD
Time Slot 16 AIS Detection Status. If time slot 16 multi-
frame alignment is lost, this bit will reflect the detection of AIS
in time slot 16.

FRM_R_FZCON
Freeze Conversion. When set to 1, this enables the conver-
sion of certain signaling codes when the signaling buffers
have been frozen. The code translation is 00 to 01 and 0000
to 0101 for 4-state and 16-state signaling, respectively.
0
14:9

RSVD
Reserved. Must write to 0.
0
0
FRM_R_SIGI
Signaling Insertion. A 1 enables the insertion of signaling
data into the Tx line. A 0 disables the insertion of signaling
data into the Tx line. This bit is valid in the Rx path only when
in transport mode; otherwise, it should be set to 0.
7
FRM_R_RXSTOMP Rx Path Stomping. For DS1 links, this bit indicates to stomp
all robbed bit signaling on voice time slots on the correspond-
ing link. Stomping of time slot 16 for CEPT links is performed
in the system interface block.
1 = will enable stomping.
0 = will disable stomping for the corresponding link.
6
5
RSVD
Reserved. Must write to 0.
FRM_R_SIGDEB
Signaling Debounce.This bit enables signal debounce on
signaling when extracted from the Rx line.
0
0
4
FRM_R_HGEN
Handling Group Enable. When set to 1 in combination with
selecting the source of signaling data to be the VT mapper,
this indicates to the signaling block that the signaling for this
link is byte sync mapped and uses the handling group format.
3
FRM_R_MSIGFZ
Manual Signaling Freeze. Used to manually halt the signal-
ing register updates when the source of signaling data is
either the VT mapper or when the signaling is extracted from
the Rx line. A 1 halts the updates.
0
* See Table 383 on page 272 for values of L and R.
