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.
FRM_T_TS16AIS
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.

Automatic TS16 Remote Frame Alarm.
Enables automatic
transmission of a 1 in the Y-bit position in the transmit path
when the receive path has lost TS16 alignment.
Reserved.
Must write to 0.
Automatic Sp Loopback.
When set, the Sp bit transmitted
for each individual HG will be set to 0 when the HG align-
ment is lost in the Rx path. Each Sp in the Tx path corre-
sponds to the same HG in the Rx path.
Manual Sp.
Used to manually force the transmission of a 0
in each of the Sp bits of the HGs on each link.
Zero Code Suppression Mode.
When set to 1, the signal-
ing block will give an indication to the frame formatter for
each of the data channels. This indication should disable the
zero-code suppression for the associated time slot. Signal-
ing insertion must be enabled for FRM_T_ZCSM to take
effect. FRM_T_ZCSM will not work when byte sync mapping
is enabled.
VT Signaling Enable.
A 1 enables the transport of signaling
to the VT mapper from the programmed signaling source in
byte sync mode. Byte sync mode cannot be enabled in con-
junction with signaling insertion (bit 8, FRM_T_SIGI). The
robbed-bit positions can be stomped while in byte sync
mode, but no signaling data can be inserted.
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.
