14:10 FRM_T_LINKCNT[4:0] Transmit Link Count. Indicates the number of links ser-
viced by the signaling block. This value should be set to 28
when the Supermapper is interfacing with only DS1 links; it
should be set to the actual number of links active for mixed
mode applications.

FRM_T_SUBZERO
Substitute Zero. A 1 forces signaling data to be 0000 for
those time slots which have a signaling state mode of no
signaling. This only applies to the signaling data trans-
ferred to the VT mapper.
4
FRM_T_FAS_NOTFAS FAS/NOTFAS Transmission. Used to force alignment of
the CEPT TS16 multiframe to a FAS or NOTFAS frame. A
0 indicates alignment to a FAS frame. A 1 indicates align-
ment to a NOTFAS frame.
