Multicell System

General Overview

Using the multicell system on Gigaset 1054isdn, you can make calls with mobile phones from
multiple base stations. By positioning the Gigaset 1054isdn strategically you can also expand the
area in which you can use your mobile unit.
You can registrate and use your mobile unit on up to 4 base stations in Gigaset 1054isdn.
Up to 8 mobile phones can be registrated on each Gigaset 1054isdn base station.
A mobile unit can make calls from each base station using the same call number (MSN).
A mobile unit can be reached with the same external call number (MSN) on each base sta-
tion
A mobile unit can switch base stations (external call) during a call.
Organization of base stations and mobile phones
The following is recommended for operating mobile phones on multiple base stations:
Number the base stations, i.e., assign a number from 1 to 4.
Define the internal number for mobile phones that are being operated on a base station (see
"Registrating Standard Mobile Unit, Comfort Mobile Unit" , page 156, 161).
Registrate the mobile unit on base station 2 using the same number as on base station 1.
Registrate the mobile phones on base stations 3 and 4, if present.
Activate the display of the base station number in each mobile unit (see page 158), not nec-
essary with comfort mobile unit (see "Activate / Deactivate the Base Station Number" , page
158).
Additionally, when using multicell system behind secondary installations with different connec-
tions:
Establish a collective call in the secondary installation so that a mobile unit can be reached at
the different connections.
Information for Usage
The mobile phones are connected to the base station through cellular radio waves, that is
shown in the actual display. All calls, both incoming and outgoing, can only be connected
through the displayed base station (even when the operational range overlaps that of the
next base station).
Internal calls are only possible within the range of the selected base station, not to other
base stations.
If the mobile unit moves into the operational range of another, new base station, the contact
to the original base station will be broken, and the connection with the new base station will
be established automatically (see "Base Station Selection Automatic / Manual / Combined" ,
page 157, 163).
The automatic selection of the base station can be deactivated. You can define manually on
which base station the mobile unit should be operated (see "Base Station Selection Automatic /
Manual / Combined" , page 157, 163). This is important when in an overlap area between two
base stations. This makes it possible to define which base station should be used.
