5. Swapping/Adding/Deleting SVP Servers
Whenever an SVP Server is removed from the system, wireless telephones that are
using the SVP Server will be affected. If the removal of the SVP Server is intentional,
the administrator should lock and idle the system prior to removing an SVP Server.
Adding an SVP Server
A new SVP Server is detected within two seconds of being added to the system
(booted/configured/connected). When detected, any wireless telephone not active in
a call will immediately be forced to reboot and check in again. Any wireless
telephone in a call will immediately switch to the SVP Server that should provide its
"timing" function. This switch should not be noticeable to the user since it is similar
to a normal handoff between APs. When the wireless telephone ends the call, it will
be forced to reboot and check in again.
Removing an SVP Server
When an SVP Server is removed from the system it is detected within two seconds.
Wireless telephones not in calls are immediately forced to reboot and check in again.
For wireless telephones active in calls, two possible scenarios can occur. If the SVP
Server that was removed was providing the "gateway" function for the wireless
telephone, then the call is lost and the wireless telephone is forced to check-in again.
If the SVP Server that was removed was providing the "timing" function for the call,
the call will switch to the SVP Server that should now provide the "timing" function.
Note that during the two seconds while the loss of the SVP Server is being detected,
the audio for the call will be lost.
Changing the Master SVP Server
In the event the master SVP Server loses communication with the network, the
wireless telephone system will fail. All SVP Servers will lock, All calls will be lost,
and no calls can be placed. Therefore, if the master SVP Server needs to be
replaced, be sure the system can be brought down with minimal call interruption. Be
sure to reset all SVP Servers after the master has been replaced. If the IP address of
the master is changed, it must be changed in all SVP Servers.
