"air": Synchronization of activated Base Stations over air, i.e. directly via
DECT, but with additional Status information by the IWU.
This method occupies - depending on the Beacon configuration - one or
more available timeslots (which cannot be used for telephony), but it
allows the seamless handover between the radio areas of synchronized
Base Stations.
The Base Station to be synchronized to must be an activated Base Station
at the IWU. This is the standard synchronisation method used.
"air ext": Synchronization of Base Stations over air, i.e. directly via DECT,
but without additional Status information by the IWU.
This method occupies - depending on the Beacon configuration - one or
more available timeslots (which cannot be used for telephony), but it
allows the seamless handover between the radio areas of synchronized
active Base Stations.
The Base Station to be synchronized to must be a Base Station confi-
gured at the IWU, but it need not be activated.
Alternatively a Base Station may also be synchronized to another Base
Station that is NOT configured at the IWU (e.g. Base Stations of other
manufacturers).
If the PARK of the external Base Station is known, it may be entered as
"PARK Default" of the Base Station to be synchronized on the page "Ari".
For the external Base Station a "Dummy" module has to be configured.
Please notice that this may result in problems regarding the so called
"Beacon Announcement" which may lead to frequent losses of synchro-
nization.
To minimize this problem an (internal) Base Station may be used as
synchronization Base Station. Therefore you have to configure "0"
channels (page "DECT - Device", entry "NumOfChannel"). No voice
connections can be established via this Base Station.
"ParkSync" (3 columns)
You can choose a Base Station resp. DECT module from the select box
on which the selected Base Station shall synchronize to (synchronization
master). The Base Station will first try to synchronize to the Base Station
in the leftmost "ParkSync" column. If this is not successful or if the
synchronization gets lost while in operation, the Base Station will try to
synchronize to the Base Station in the middle "ParkSync" column and
finally to the rightmost column.
Only when the synchronization to all 3 entered Base Stations is not
successful, a synchronized operation and therefore a seamless handover
will no longer be possible.
Note regarding the synchronization sequence:
For the operation of several synchronized Base Stations the synchroni-
zation sequence shall be configured as a "chain", i.e. the second Base
Station synchronizes to the first, the third Base Station to the second, the
fourth to the third and so on.
If all Base Stations synchronize to one single "Master" Base Station a
