Receive Spare Bit for International Use
First bit of the received service word. It is fixed to one if CRC-
multiframe mode is enabled.
Receive Remote Alarm
Equivalent to bit FRS0.RRA.
Receive Spare Bits for National Use (Y-Bits, Sn-Bits, Sa-Bits)
Submultiframe Error Indication 1, 2
Not valid if doubleframe format is enabled. In this case, both bits are
set to logical ‘1’.
When using CRC-multiframe format these bits are set to
Both flags will be actualized with beginning of every received CRC
multiframe.
If automatic transmission of sub-multiframe status is enabled by
setting bit XSP.AXS, above status information will be inserted
automatically in S

disabled):
