OpenScape Cordless IP V2 – Introduction
• Provide cell site DECT functions
• Provide media processing from handset directly towards Communication System
• Provide up to 12 DECT full slot pairs (zero blind slot)
• Provide up to 6 DECT long slot pairs (wideband)
Configuring the base stations p. 27
• Handsets (mobile devices)
• Per DECT manager 250 handsets can be connected by roaming and 60 DECT calls could be made simulta-
neously for VoIP calls, network directory sessions and info center sessions.
• Subscribers can accept or initiate calls in all DECT cells with their handset ( Roaming ), and can also switch
between the DECT cells during a call ( Handover ). A handover is only possible if cells are synchronised.

• Communication System
You can connect your DECT telephone system to a Communication System for VoIP, ISDN or analogue
telephony, e.g.,
• OpenScape Business
• OpenScape 4000
• OpenScape Voice
The Communication System
• Establishes the connection to a public telephone network
• Enables central management of telephone connections, directories, network mailboxes
• Forming clusters
A cluster defines a set of base stations of a DECT manager that shall synchronise in order to perform handover,
roaming and overload balancing.
Handover means to switch a handsets DECT connection to a new base station during a call.
Roaming means to connect a handset in idle mode via a new base.
Overload balancing is the process to setup a DECT connection (for a call or other administrative or customer
purpose) not at the current base station, which is fully loaded with active DECT or media connections, but via
a neighbour base station, which has free resources to setup/accept the new DECT connection.
Handover and overload balancing could only be provided by synchronised base stations. In some cases, not all
base stations connected to one DECT manager can be synchronised for location specific reasons. To organize
synchronisation just within a subset of base stations connected to one DECT manager, you can form clusters,
within a DECT manager.
A DECT manager can offer multiple clusters with base stations synchronised within the cluster, but not
synchronised along different clusters.
In future multiple DECT manager integrations, DECT managers could be synchronised by defining
synchronisation between clusters of different DECT managers.
