via a repeater are always handled via the repeater sync source.
Repeater chain
If a repeater has another repeater specified as the synchronisation source,
one refers to a repeater chain. None of the DECT radios in a repeater chain
can be specified as the synchronisation source for an IP1200 DECT radio.
For repeater chains, special rules apply.

interval required to send a signal from a source to the receiver over the
