Base station synchronisation
Activating/deactivating the base station
A base station must be active to manage the calls of the connected handsets. If it is deactivated, it will no longer
connect handsets but it still stays in the list of connected base stations.

managed by the base station are terminated.
6.2 Base station synchronisation
Synchronisation and the logical structuring of the base stations in clusters are prerequisites for the functioning of
the multicell system, intercell handover, and (over)load balancing. Overload balancing means that a handset can
roam to a free base, when current base is fully loaded and cannot accept further handset connections.
Base stations can be synchronised "over the air", meaning that they are synchronised via DECT. If the DECT con-
nection between specific base stations seems to be not reliable enough, synchronisation can also take place via
LAN. To carry out the synchronisation you will need the plan of the clusters with the synchronisation level for each
base station.
For detailed information on DECT network planning, please refer to the "HiPath Cordless IP – Service Documen-
tation".
6.2.1 Synchronisation planning
Base stations that combine to form a DECT wireless network must synchronise with one another to ensure a
smooth transition of the handsets from cell to cell (handover). No handover and no (overload) balancing is possible
between cells that are not synchronised. In the event of loss of synchronisation, the base station stops accepting
calls once all ongoing calls that were being conducted on the asynchronous base station have ended and then it
re-synchronises the asynchronous base station.
The synchronisation within a cluster takes place in a master/slave procedure. This means that one base station
(sync master) defines the synchronisation cycle for one or more other base stations (sync slaves).
Please ensure that the base station you want to deactivate is not on sync level 1. Check your sync
settings before deactivating a base station. Otherwise your system may no longer work properly
Synchronisation always refers to a cluster. In case you set up several clusters that are not
synchronised with one another, there will be no possibility of a handover or (over)load balancing
between them.
A base station shows its synchronisation status with an LED ( p. 14).
