AVPP Maintenance

Using SendAll
In an IP system with multiple AVPP's, the SendAll option is provided to speed configuration and ensure
identical settings. The S=SendAll option allows you to send that configuration parameter to every AVPP
on the LAN.
SendAll can only be used after the IP address is established on each AVPP via the serial connection. If
you anticipate identical settings across the LAN, set the IP address and custom hostname (if desired) for
each AVPP using the initial serial connection. Connect via the LAN and use SendAll to set identical
configuration options for all AVPP's.
If SendAll is to be utilized in your system, all passwords must be identical.
• Warning
Do not change the password at the initial configuration if SendAll is desired.
Use the default password and change it globally, if desired, after a LAN connection is established for all
AVPP's. If independent administration of each AVPP is desired, the passwords may be set at initial
configuration.
• The IP address of the master AVPP can be changed in this menu. After rebooting the system,
you can change alias IP addresses in each of the other AVPP servers without error.
Adding an AVPP
Whenever an AVPP is added to the system, the change is seamless and does not affect the wireless
phone calling functionality.
In the IP PBX environment, a new AVPP is detected within two seconds of being added to the system
(booted/configured/connected). When detected, any wireless phone that is not active in a call will
immediately be forced to check out and check in again. Any wireless phone in a call will immediately
switch to the AVPP that should provide its 'timing' function. This switch should not be noticeable to the
user since it is similar to a normal handoff between access points. When the call is ended, the wireless
phone will be forced to checkout and checkin again.
Removing an AVPP
Whenever an AVPP is removed from the system, wireless phones that are using the system will be
affected. If the removal of the AVPP is intentional, the administrator should lock and idle the system,
prior to removing an AVPP.
When a AVPP is removed from the system, it is detected within two seconds. Wireless phones not active
on calls are immediately forced to check out and check in again. During the two seconds while the loss
of the AVPP is being detected, the audio for the call will be lost.
For wireless phones active in calls, two possible scenarios can occur:
• If the AVPP that was removed was providing the 'gateway' function for the wireless phone, then
the call is lost and the wireless phone is forced to check in again.
•
If the AVPP that was removed was providing the 'timing' function for the call, then call will switch
to the AVPP that should now provide the 'timing' function.
Changing the Master AVPP
In the event the master AVPP loses communication with the network, the wireless phone system will fail.
All AVPP's will lock and all calls will be lost and no calls will be able to be placed. Therefore, if the master
AVPP needs replacing, be sure that the system can be brought down with minimal call interruption. Be
sure to reset all AVPP's after the master has been replaced. If the IP address of the master is changed,
it must be changed in all AVPP's.
