NetLink e340/h340 Wireless Telephone: The NetLink e340/h340 Wireless 
Telephone is a lightweight, durable handset specifically designed for mobile 
workplace use within a facility using the supported Mitel Networks IP telephony 
system and 802.11b APs in a wireless LAN.  
NetLink i640 Wireless Telephone: The NetLink i640 Wireless Telephone offers a 
durable design with push-to-talk functionality. 
Handset functionality is provided by emulating the Mitel Networks 5220 IP Phone. 
Among other features, the handset can receive calls directly, receive transferred calls, 
transfer calls to other extensions, and make outside and long distance calls (subject 
to the restrictions applied in your facility.) The handsets are to be used on-premises; 
they are not cellular or satellite phones. 
NetLink e340/h340/i640 Wireless Telephones use Direct Sequence Spread 
Spectrum radio technology (DSSS) to transmit audio packets over wireless LAN APs 
that support SpectraLink Voice Priority (SVP). 
NetLink SVP Server: SpectraLink Voice Priority (SVP) is the SpectraLink quality of 
service (QoS) mechanism that is implemented in the handset 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 compatible 
with the IEEE 802.11b standards.  
The NetLink SVP Server is an Ethernet LAN appliance that works with the AP to 
provide QoS on the wireless LAN. All MiNET packets to and from the NetLink 
e340/h340/i640 Wireless Telephones pass through the NetLink SVP Server and are 
encapsulated for prioritization as they are routed to and from the supported Mitel 
Networks VoIP solution or other handset.  
Mitel Networks IP System: Mitel Networks 3300 or SX-200 ICP VoIP solution. 
Access Points: (APs) are supplied by third party vendors and provide the 
connection between the wired Ethernet LAN and the wireless (802.11b) LAN. APs 
must be positioned in all areas where NetLink Wireless Telephones will be used. The 
number and placement of APs will affect the coverage area and capacity of the 
wireless system. Typically, the requirements for use of NetLink e340/h340/i640 
Wireless Telephones are similar to that of wireless data devices.  
APs must utilize SpectraLink Voice Priority (SVP). Contact SpectraLink, or a 
certified SpectraLink distributor, for information about APs that support SVP. 
Ethernet Switch: Interconnects multiple network devices, including the NetLink 
SVP Server, the supported Mitel Networks IP telephony system, Mitel Networks IP 
Phones and the APs. Ethernet switches provide the highest performance networks, 
which can handle combined voice and data traffic, and are required when using the 
NetLink e340/h340/i640 Wireless Telephones. 
Although a single Ethernet switch network is recommended, the handsets and the 
NetLink SVP Server can operate in larger, more complex networks, including 
networks with multiple Ethernet switches, routers, VLANs, and/or multiple subnets,
