A new command or indication will be recognized valid after it has been detected in two
to five successive IOM
before they are recognized). Indications are strictly state orientated. Refer to the state
diagram in the following section for commands and indications applicable in various
states.
Commands have to be applied continuously on DIN until the command is validated by
the DFE-T V2.2 and the desired action has been initiated. Afterwards the command may
be changed.
An indication is issued permanently by the DFE-T V2.2 on DOUT until a new indication
needs to be forwarded. Because a number of states issue identical indications it is not
possible to identify every state individually.
