For a correct start up of the primary access interface, a set of parameters specific to the
system and hardware environment must be programmed after RES goes inactive. Both
the basic and the operational parameters must be programmed before the activation
procedure of the PCM line starts. Such procedures are specified in ITU-T and ETSI
recommendations (e.g. fault conditions and consequent actions). Setting optional
parameters makes sense mainly when basic operation via the PCM line is guaranteed.

control bits that are to be programmed in one of the above steps. The sequence is
recommended but not mandatory. Parameters for the basic and operational set up, for
example, may be programmed simultaneously.
