First bit of the received service word. It is fixed to one if CRC-
multiframe mode is enabled.
Equivalent to bit FRS0.RRA.
Submultiframe Error Indication 1, 2
Not valid if doubleframe format is enabled. In this case, both bits are
set.
When using CRC-multiframe format these bits are set to
Both flags are updated with beginning of every received CRC
multiframe.
If automatic transmission of sub-multiframe status is enabled by
setting bit XSP.AXS, above status information is inserted
automatically in S

If multiframe alignment has been lost, or
if the last multiframe has been received with CRC error(s). SI1
flags a CRC error in last sub-multiframe 1, SI2 flags a CRC
error in last sub-multiframe 2.
If at multiframe synchronous state last assigned sub-multiframe
has been received without a CRC error.
