3616 Wireless IP Telephone
– The 3616Wireless IP Telephone is a lightweight, durable handset
specifically designed for mobile workplace use within a facility using the Avaya Call Server and
802.11 APs in a wireless LAN.

3626 Wireless IP Tel
ephone
– The 3626 Wireless IP Telephone offers a durable design with push-
to-talk functionality.
Wireless Telephone functionality is provided by emulating the Avaya 4606 telephone. The
Wireless Telephone supports five predefined feature keys and a mixture of six programmable line
and feature keys. Among other features, the Wireless 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 Telephones are
to be used on-premises; they are not cellular or satellite phones.
3616/26 Wireless IP Telephones use direct sequence spread spectrum radio technology (DS) to
transmit audio packets over wireless LAN APs that support the Avaya Wireless PC card.
Avaya Voice Priority Processor
– SpectraLink Voice Priority (SVP) is the Quality of Service (QoS)
mechanism that is implemented in the Wireless Telephone and AP 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 compliant with the IEEE 802.11 and 802.11b standards.
The Avaya Voice Priority Processor is an Ethernet LAN appliance that works with the AP to
provide QoS on the wireless LAN. All packets to and from the 3616/26 Wireless IP Telephones
pass through the Avaya Voice Priority Processor and are encapsulated for prioritization as they are
routed to and from the Avaya Call Server.
SVP is required for QoS because the current IEEE 802.11b wireless LAN standard provides no
mechanism for differentiating audio packets from data packets. This standard is undergoing
revision to version 802.11e to provide all the functionality of SVP in an industry standard thus
ensuring high-quality voice in a mixed client environment. Once 802.11e is ratified, Avaya and its
802.11 technology partners will adopt the new specification.
Avaya Call Server
– the call-processing component of the Avaya IP telephony solution.
Access Points
– provide the connection between the wired Ethernet LAN and the wireless (802.11)
LAN. Access points must be positioned in all areas where Wireless 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 3616/26 Wireless IP Telephones are similar to that
of wireless data devices.
Ethernet Switch
– interconnects multiple network devices, including the Avaya Voice Priority
Processor, Avaya Call Server, 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 3616/26 Wireless IP Telephones.
