2.3 System Components
• 3616 Wireless IP Telephone
– The 3616 Wireless 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.
• 3620 Wireless IP Telephone –
The 3620 Wireless Telephone is uniquely designed to meet the
challenging needs of the healthcare workplace. With more durable plastics, backlit keypad, and
multiple charging options, this handset is especially suited for 24-hour shift-based environments.
Note that the battery pack for the 3620 is not interchangable with the battery pack for the 3616.
• 3626 Wireless IP Telephone
– The 3626 Wireless IP Telephone offers a durable design with
push-to-talk functionality.
Wireless Telephone functionality is provided by emulating the Avaya IP 4612 telephone. The 3600
Series Wireless Telephones support five predefined feature keys and a mixture of twelve
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.
3600 Series Wireless 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 3600 Series Wireless Telephones pass
through the Avaya Voice Priority Processor and are encapsulated for prioritization as they are
routed to and from the Avaya Call Server.
•
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 3600 Series Wireless 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 3600 Series Wireless Telephones.
Although a single Ethernet switch network is recommended, the Wireless Telephones and the
Avaya Voice Priority Processor can operate in larger, more complex networks, including networks
with multiple Ethernet switches, routers, VLANs and/or multiple subnets. However, in such
networks, it is possible for the Quality of Service (QoS) features of the Avaya Voice Priority
Processor to be compromised and voice quality may suffer. Any network that consists of more than
a single Ethernet switch should be thoroughly tested to ensure any quality issues are detected.
