If automatic transmission of sub-multiframe status is enabled by
setting bit XSP.AXS and the receiver has been lost multiframe

Transmit Spare Bit For International Use (FAS Word)
First bit in the FAS word. Only significant in doubleframe format. If not
used, this bit should be fixed to ‘1’. If one of the time slot 0 transparent
modes is enabled (bits XSP.TT0, or TSWM.TSIF), bit XSP.XSIF is
ignored.
Transmit Spare Bit (Frame 13, CRC-Multiframe)
First bit in the service word of frame 13 for international use. Only
significant in CRC-multiframe format. If not used, this bit should be
fixed to ‘1’. The information of XSP.XS13 is shifted into internal
transmission buffer with beginning of the next following transmitted
CRC multiframe.
If automatic transmission of submultiframe status is enabled via bit
XSP.AXS, or, if one of the time slot 0 transparent modes XSP.TT0 or
TSWM.TSIS is enabled, bit XSP.XS13 is ignored.

Information of submultiframe status bits RSP.SI1 and RSP.SI2
is inserted automatically in S
multiframe (RSP.SI1

one of the time slot 0 transparent modes XSP.TT0 or
TSWM.TSIS is enabled, bit XSP.AXS has no function.
