5.4.7 DECT synchronisation
The two synchronisation ports of the CPU card are used to spread DECT synchronisation in a
contiguous multi-site configuration, as shown in the diagram below:
The synchronisation port is used to transport network synchronisation and DECT synchronisation in
case of a DECT multi-site with contiguous cells. Then it does not require any third-pair wiring between
the base stations.
Continuous service is ensured by duplicating the master switch. Moreover, the synchronisation chain
is not necessarily cut in case of slave switch stop.
This synchronisation port network wiring guarantees a secure DECT synchronisation.
