Out Of Range Beep - Avaya DECT R4 Installation And Administration Manual

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, select Systems > System x > Early encryption enable
2. From the Value column, select "true" from the pull-down menu.
Note:
Problems may be experienced with early encryption if the management and
Note:
control frames passed from the handset MAC layer to the IP addressing layer are
disturbed and lose their integrity. This can occur where RF propagation is
disturbed, for example, if the handset is being used in an environment where
highly reflected metallic surfaces are used in the construction of the locale.
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".

Out of range beep

The behavior of the handset when moving out of coverage area of the connected DECT system
can be configured at Settings > Sound and Alerts > Out of range alert. The handset can
either be silent when loosing the system or do a single beep or beep every minute for the next
30 minutes to alert the user that the system is out of range.
Handset idle roaming
It is recommended to set the new parameter Location > Base station positioning to Off.
Otherwise there will be a strange roaming behavior in the handset that could cause some
undefined side effects. Additionally, the battery standby time will be reduced if the parameter is
set to On.
This parameter was introduced for the hotfix Version 2.8.30 in the 3725 Handset only to improve
the idle roaming behavior in this load as a short-term fix. The handset will search every few
seconds for the IPBS with the best signal strength. In later handset releases, a more optimized
idle roaming behavior was introduced, which is always active (for 3720 as well) and has much
less impact on the battery standby time. The parameter has to be kept in the parameter
definition to be able to set it to Off in case of updating the handset from the hotfix release 2.8.30
to a later release where this parameter is not needed anymore.
