the interconnections and extensions contained in the telegram are locked.
For p0922 = 999, the following applies: p2079 can be freely set. If p2079 is also set to
999, then all interconnections can be set.
For p0922 = 999 and p2079 < 999, the following applies: The interconnections
contained in the telegram are locked. However, the telegram can be extended.
