4.2 Registering the telephone on other systems
The telephone can be registered on several systems (maximum of 4).
Note: the input is usually reserved for use with your main Alcatel-Lucent Enterprise system. You can
select the other inputs to register the telephone under another system (Alcatel-Lucent Enterprise or
other system).
4.2.1 To make a new registration, when the telephone has already been registered on one
or more systems, proceed as follows
• If the registration operation runs correctly (Subscription accepted), the telephone is ready for use,
and the radio coverage icon appears.
• If the registration operation has not been successful, the station proposes launching the subscription
again.
• Depending on the type of system concerned, registration may require one or more additional
operations on the system.
During registration phase, to improve security and optimize registration in a multi-system environment,
the handset enforces a minimum signal strength level to accept to register to a base station. To achieve
the conditions, it is recommended to perform registration in a place where a base station is in direct
visibility within a 20 m range. If base station is not visible the range shall be lowered.
During registration phase in a multi-system environment, all systems are scanned without priority. The
system is selected when the signal strength is above a certain level and registration matches.
