If one of the time-slot 0 transparent modes XSP.TT0 or XSP.TT0S is enabled, bit XSP.AXS
has no function.
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,
XSP.TT0S or EMOD.TT0X), bit XSP.XSIF will be ignored.
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
will be shifted into internal transmission buffer with beginning of the next following
transmitted CRC multiframe (refer to RSP.XFLG).
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 XSP.TT0S is enabled, bit XSP.XS13 will be
ignored.
First bit in the service word of frame 15 for international use. Only significant in CRC-
multiframe format. If not used, this bit should be fixed to ‘1‘. The information of XSP.XS15
will be shifted into internal transmission buffer with beginning of the next following
transmitted CRC multiframe (refer to RSP.XFLG).
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 XSP.TT0S is enabled, bit XSP.XS15 will be
ignored.
