Reserved. Must write to 0.
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.
Reserved. Must write to 0.
Tx Path Stomping. For DS1 links, this bit indicates to stomp
all robbed-bit signaling on voice time slots on the corre-
sponding link to 0. Stomping time slot 16 for CEPT links is
done by inserting all ones using the signaling registers. A 1
will enable stomping. A 0 will disable stomping for the corre-
sponding link.
Reserved. Must write to 0.
Handling Group Enable. When set to 1 in combination with
(bit 9, FRM_T_VTSIGE), this bit indicates to the signaling
block that the signaling for this link is byte sync mapped and
uses the handling group format.
Manual Signaling Freeze. Used to manually halt the signal-
ing register updates when the source of signaling data is
either the Rx system or the Rx line. A 1 halts the updates.
