2. SpectraLink e340/i640 Wireless
Telephone Overview
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 Nortel 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 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.
