Multiple SVP Servers
Multiple SVP Server environments are those which have more than
one SVP Server. Up to 16 SVP Servers may be installed in any one
subnet.
The Timing Function
In the SpectraLink Gateway environment, SVP Servers provide the
"timing" function for active calls. In multiple SVP Server
environments, the active calls are distributed across the SVP Servers.
The number of active SVP Servers is determined dynamically.
Whenever SVP Servers are added to or removed from the system, the
distribution of the "timing" function for active calls is affected.
The addition of an SVP Server is detected as soon as the new SVP
Server is up and running. The new SVP Server will immediately start
providing the “timing” function for the appropriate wireless
telephones. The user should not detect any change. The removal of an
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, it may lose
contact with its Gateway, resulting in a check-out/check-in sequence.
If the wireless telephone was in a call, the audio will be lost and the
call will be dropped.
