10.2.1 Dual operation
Simultaneous operation of base stations via U
pn
access and base stations via
Ethernet access is possible with the OpenCom 100. Transparent handovers, for
example, are only possible when between DECT base stations using the same
access technology. When switching over to a DECT base station using different
access technology, a DECT terminal automatically re-establishes a connection
(roaming).
Be sure to keep the PARK ID of your OpenCom 100 in mind. The PARK ID is dis-
played under
System Info
:
Versions
in the
Configurator
. If the PARK ID starts with
31, there may be an attempt at a handover between DECT base stations using dif-
ferent access technology. In this case, make sure that the signal areas of the DECT
base stations using different access technology do not overlap. If the PARK ID
starts with a different value (e. g. 30), prevention of unintentional handovers is
effective.
10.2.2 Synchronisation
Transmissions of all DECT base stations at a single location must be synchronised
in order that DECT terminals are able to receive multiple DECT base stations simul-
taneously. Synchronisation can be conducted via U
pn
access. It cannot be con-
ducted via an Ethernet/IP connection. DECTnetIP base stations are thus synchro-
nised via wireless connection.
When planning a larger sized DECT network, it is advisable to take the following
points into consideration:
■
All DECTnetIP base stations at a single location must be able to receive at least
one neighbouring base station. Synchronisation requires less signal strength
than a voice connection does.
■
Synchronisation range is increased using multiple base stations. To decrease
the probability of a connection breakdown, base stations should not be
arranged in chain formation. The signal should be distributed with a network
that is as extensive as possible and where each base station is supported by
multiple synchronisation partners.
■
To re-synchronise, first wait for all current connections to be terminated.
