The SpectraLink e340/i640 Wireless Telephone is a mobile handset for workplace IP 
telephone systems. The Wireless Telephone operates over an 802.11b wireless Ethernet 
LAN providing users a wireless voice over IP (VoIP) extension. By seamlessly 
integrating with the 

Mitel Networks IP telephony system, Wireless Telephone users are  

provided with high-quality mobile voice communications throughout the workplace. The  

Wireless Telephone gives users the freedom to roam throughout the workplace while  

providing all the features and functionality of an IP desk phone. 
The NetLink e340/i640 Wireless Telephone provides a wireless extension to the Mitel 
Networks 

3300 ICP and SX-200 ICP VoIP solutions. The Wireless Telephone supports the 

MiNET protocol, a proprietary protocol developed by Mitel Networks for communication 

between a Mitel Networks IP phone and a Mitel Networks PBX. 
The Wireless Telephones reside on the wireless LAN with other wireless devices using 
Direct Sequence Spread Spectrum (DSSS) radio technology. The handset radio transmits 
and receives packets at up to 11Mb/s. The SpectraLink e340/i640 Wireless Telephone 
supports Wired Equivalent Privacy (WEP) as defined by the 802.11b specification. 
SpectraLink offers the product with both 40-bit and 128-bit encryption. WEP increases 
the security of the wireless LAN to a level similar to a wired Ethernet LAN. 









IP multicast addresses are used by the SpectraLink i640 Wireless 
Telephone system. This requires that multicasting be enabled on the 
subnet used for the NetLink Wireless Telephones, SVP Server, and 
Telephony Gateways. 

Routers are typically configured with filters to prevent multicast traffic 
from flowing outside of specific domains. The wireless LAN can be 
placed on a separate VLAN or subnet to reduce the effects of broadcast 
and multicast traffic from devices in other network segments.
