DECT over IP
®
Dual Operation
Simultaneous operation of base stations via U
pn
access and base
stations via Ethernet access is possible with the Forum 525/526.
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 con-
nection (roaming).
Be sure to keep the PARK ID of your Forum 525/526 in mind. The
PARK ID is displayed under

Versions
in the
Con-
figurator
. If the PARK ID starts with 31, there may be an attempt
at a handover between DECT base stations using different access
technology. In this case, make sure that the signal areas of the
DECT base stations using different access technology do not over-
lap. If the PARK ID starts with a different value (e. g. 30), preven-
tion of unintentional handovers is effective.
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 simultaneously. Synchronisation can
be conducted via U
pn
access. It cannot be conducted via an Ether-
net/IP connection. DECT over IP 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:
z
All DECT over IP base stations at a single location must be able
to receive at least one, or even better, two neighbouring base
stations. Synchronisation requires less signal strength than a
voice connection does.
z
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.
