E1 FRMG International Bits Control (042H, 0C2H, 142H, 1C2H, 242H, 2C2H, 342H, 3C2H)
Si[1:0]:
into the first of each FAS frame and NFAS frame respectively. When CRC Multi-Frame generation is enabled (GENCRC is logic 1) and FEBE indica-
tion is disabled (FEBEDIS is logic 1), the values programmed in the Si[1] and Si[0] bit positions are inserted into the E1 & E2 bit positions respectively.
When GENCRC is logic 1 and FEBEDIS is logic 0, both Si[1] and Si[0] are ignored.
E1 FRMG Extra Bits Control (043H, 0C3H, 143H, 1C3H, 243H, 2C3H, 343H, 3C3H)

Valid when the FDIS (b3, E1-040H) and the INDIS (b1, E1-040H) are logic 0.
When CRC Multi-Frame generation is disabled (GENCRC is logic 0), the Si[1] and Si[0] bits can be programmed to any value and will be inserted
Valid when the FDIS (b3, E1-040H), the XDIS (b0, E1-040H), the SIGEN (b6, E1-040H) and the DLEN (b5, E1-040H) are all logic 0.
Replace the extra bits located in bits 5, 7 & 8 in TS16 of frame 0 of the Signaling Multi-Frame.
