5-2 Swapping/Adding/Deleting SVP Servers
SVP Server Installation, Setup, & Maintenance Manual - Revision 1
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 checkin 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.
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 and all calls will be lost and no calls will be able to 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.
UNIVERGE WL System Telephony Gateway
In a Telephony Gateway environment, the addition of a SVP Server is
detected as soon as the new SVP Server is running. The new SVP
Server immediately starts providing the “timing” function for the
appropriate Wireless Telephones. The user should not detect any
change. The removal of a SVP Server is detected within one minute.
During this time, any Wireless Telephone that was using the SVP Server
that was removed will be affected. If the Wireless Telephone was not
in a call, the Wireless Telephone may lose contact with its gateway,
resulting in a checkout/checkin sequence. If the Wireless Telephone
was in a call, the audio will be lost and the call will be dropped.
There is no master SVP Server in a UNIVERGE WL System Telephony
Gateway environment.
NOTE
During the two seconds while the loss of the SVP Server is being detected,
the audio for the call will be lost.
