System Components

Avaya 3641/3645 Wireless IP Telephone
The Avaya 3641 Wireless IP Telephone is a lightweight, durable handset specifically
designed for mobile workplace use within a facility using the Avaya Communication
Manager and 802.11 APs in a wireless LAN.
The Avaya 3645 Wireless IP Telephone offers a durable design with push-to-talk
functionality.
Wireless IP Telephone functionality is provided by emulating the Avaya IP 4612
telephone. The Avaya 3641/3645 Wireless IP Telephones support six predefined feature
keys and a mixture of twelve programmable line and feature keys. Among other features,
the Wireless IP Telephone can receive calls directly, receive transferred calls, transfer
calls to other extensions, make conference calls, and make outside and long distance calls
(subject to the restrictions applied in your facility.) The Wireless IP Telephones are to be
used on-premises; they are not cellular or satellite phones.
Avaya 3641/3645 Wireless IP Telephones use direct-sequence spread spectrum radio
technology to transmit audio packets over wireless LAN APs that support the Avaya
Wireless PC card.
Avaya Voice Priority Processor
The Avaya Voice Priority Processor (AVPP) is an Ethernet LAN appliance that works with
the AP to provide QoS on the wireless LAN. All packets to and from the Avaya 3641/3645
Wireless IP Telephones pass through the Avaya Voice Priority Processor and are
encapsulated for prioritization as they are routed to and from the Avaya Communication
Manager.
SpectraLink Voice Priority (SVP) is the Quality of Service (QoS) mechanism that is
implemented in the AVPP, Wireless IP Telephones and APs to enhance voice quality over
the wireless network. SVP gives preference to voice packets over data packets on the
wireless medium, increasing the probability that all voice packets are transmitted
efficiently and with minimum or no delay. SVP is fully compatible with IEEE 802.11b
standards.
Avaya Communication Manager
The Avaya Communication Manager is the call-processing component of the Avaya IP
telephony solution.
Access Points
Access points (APs) provide the connection between the wired Ethernet LAN and the
wireless (802.11) LAN. Access points must be positioned in all areas where Wireless IP
Telephones will be used. The number and placement of access points will affect the
coverage area and capacity of the wireless system. Typically, the requirements for use of
Avaya 3641/3645 Wireless IP Telephones are similar to those of wireless data devices.
Ethernet Switch
Ethernet switches interconnect multiple network devices, including the Avaya Voice
Priority Processor, Avaya Communication Manager, Avaya IP Phones and the access
points. Ethernet switches provide the highest performance networks, which can handle
combined voice and data traffic, and are required when using the Avaya 3641/3645
Wireless IP Telephones.
