IED
G.703 reception failure detected in GIF200
(iii)
If the GIF200 does not receive any data from the MUX, the GIF200 unit sends TX data
consisting of all '1' bits for the GRL200 IED. As a result, the IED gets to detect the error
status of the MUX.

G.703 transmission failure detected in MUX
(iv)
If the MUX cannot receive data from the GIF200, the MUX issues the AIS by setting '1' to all
bits in the frames, the AIS information is transferred to the remote MUX.
