3.4.4.2
The output of the Quad IEC DFE-T, e.g. infos on Uk0 or C/I-channel contents, usually
depends only on the given state of the Quad IEC DFE-T control unit. In some states,
several outputs are possible depending on input. If RES is not set to low or TSP isn’t set
to high, only the control of loops is state independent and is evaluated from the C/I-
channel input.
ARL
AR2
AR4
Any other C/I-channel input, low at RES or high at TSP, causes the analog loop to be
opened and the M symbol to be set to zero.

In this section, each state is described with its inputs, its outputs and its meaning. Unless
described otherwise, the activation controller performs the following actions:
