Configuring DECT managers
•
N870 IP PRO DECT base stations
•
Provide cell site DECT functions
•
Provide media processing from handset directly towards PBX
•
Provide connection channels for the handsets, the number depends on various factors
such as the approved bandwidth and the device role
Configuring the base stations
•
Handsets (mobile devices)
•
Per DECT manager up to 250 handsets can be connected. To allow inter-DECT-manager
roaming, the regular load of handsets planned to be attached to one DECT manager
should be lower (approx. 80 %).
60 DECT calls could be made simultaneously for VoIP calls, network directory sessions
and info center sessions. For information on handset functions in relation to Gigaset base
stations, visit wiki.gigasetpro.com.
•
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 pos-
sible if cells are synchronised.
Configuring handsets
Detailed information about approved Gigaset handsets can be found in the relevant user
guide. These are provided on the Internet at wiki.gigasetpro.com.
•
PBX (Private Branch Exchange)
You need to connect your DECT telephone system to an IP PBX or Provider with VoIP (SIP)con-
nections, e.g.,
•
On premise PBX
•
Hosted PBX
•
Cloud PBX
•
VoIP Provider
The PBX
•
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 adminis-
trative 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.
While handover and roaming is possible between base stations of different DECT managers,
overload balancing is only possible inside the area of one DECT manager.
