White Paper

1.2 General WLAN environment

The Avaya wireless telephones need a correctly configured WLAN environment. This means using

proper channel allocation – the strongest Access Point (AP) should be on different channel than the

next strongest AP – and the use of a pre-installation/post-installation Site Survey to certify installation.

Depending on the planned Avaya phone type there are different requirements which should be met to

avoid disturbances in the final system (table 4).

1.3 Add on WLAN device - Avaya Voice Priority Processor

The Avaya Voice Priority Processor (AVPP) is an Ethernet LAN device that works with the AP to pro-

vide QoS on the wireless LAN. Voice packets and call signalling to and from the Avaya WTs are inter-

cepted by the AVPP and encapsulated for prioritization as they are routed to and from an IP telephony

server or gateway. The main characteristics are

• an Ethernet LAN appliance that works with the AP to provide QoS on the wireless LAN

• all packets to and from the 3641/3645 Wireless IP Telephones are sent through the Avaya Voice

Priority Processor and are encapsulated for prioritization as they are routed to and from the

3641/3645 handsets.

• AVPP also provides bandwidth admission control and aids telephones in power management

The AVPP may also be referred to as SVP (Spectralink Voice Processor). This is the same device

(hardware & software) with Spectralink logo and labels – may be found especially in older installations.

Note this device is required for the Avaya 3641/3645 handsets only.
