5 Handset Configuration
• Automatic lock time: specifies the time that elapses before the handset is automatically
locked. The shortest time that may be specified before the phone lock is applied is 5
seconds and the longest time is 3 minutes.
5.18 Disable Homebase GAP Registration
When the feature is enabled, it is not possible to register to a home base.
Using the "Edit template" feature in the PDM/Device Manager, the parameter can be found
at
Systems > Home_Base_Subscription.
The parameter is set to "Enable" for registration of a new base station. The default value is
"Disable".
5.19 Require Encrypted Base Station
The handset can be configured to set up calls via encrypted base stations only. This is used
to avoid snooping in the telephony network.
Requirements:
• The encryption is enabled in the base station.
See corresponding manual for the base
station.
• If Ascom´s base station is used, the software version must
be 3.1.x or higher.
Using the "Edit template" feature in the PDM/Device Manager, the parameter can be found
at:
Systems
> Encryption required.
When the parameter is set to "Yes", only call setup via encrypted base stations are possible.
The default value is "No".
5.20 Early Encryption
Early encryption is used when enhanced DECT security is activated in the base station. This
means that the radio link is encrypted early before data is transmitted.
To enable early encryption in the handset, the "Early encryption enable" parameter is set via
the PDM in the following way:
1 From the PDM/Device Manager, select Systems > System x
2 Select "true" from the Early Encr
yption enable drop-down list
If users experience connection problems when early encryption is turned
on, the function
may be turned off in the handset by reconfiguring the handset through the PDM and setting
the value of the parameter to "false". This can occur, for example, when the handset is being
used in an environment where highly reflected metallic surfaces are used in the construction
of the locale.
5.21 Base Station Location
The approximate location of the handset can be sent with an alarm. The handset evaluates
the field strength ratio of the individual radio base stations and sends the best-rated Base
Station ID to indicate an approximate location of the handset.
