Sn[4:0]:

Bits 4 to 0 of this register are substituted in bit positions 4 to 8, respectively, of

TS0 of each NFAS frame when framing generation (FDIS = 0) and

International/National bit control (INDIS = 0) is enabled. When FDIS or INDIS

is logic 1, the contents of this register are ignored and replaced with the

values received on the BTPCM[x] input.

The bits Sn[4:0] correspond to the 5 National bits; these can be programmed

to any value and are inserted into the National bit positions in the NFAS

frames when enabled by INDIS.

Si[1:0]:

The bits Si[1] and Si[0] correspond to the International bits. The Si[1] and

Si[0] bits can be programmed to any value and will be inserted into bit 1 of

each FAS frame and NFAS frame, respectively, when the block is configured

for frame generation, INDIS is set to logic 0, and CRC multiframe generation

is disabled. When CRC multiframe generation is enabled, both Si[1] and Si[0]

are ignored if FEBE indication is enabled; if FEBEDIS is a logic 1 and INDIS =

0, the values programmed in the Si[1] and Si[0] bit positions are inserted into

the spare bit locations of frame 13 and frame 15, respectively, of the CRC

multiframe. If both FEBEDIS and INDIS are logic 1, then data from BTPCM[x]

replaces the Si[0] and Si[1] bits in the CRC multiframe.

The Si[1], Si[0], and Sn[4:0] bits should be programmed to a logic 1 when not

being used to carry information.
