2. NetLink e340/i640 Wireless Telephone Overview

The NetLink e340/i640 Wireless Telephone is a mobile handset for workplace IP telephone systems. NetLink Wireless Telephones operate over an 802.11b wireless Ethernet LAN providing users a wireless voice over IP (VoIP) extension. By seamlessly integrating with the Mitel IP telephony system, NetLink Wireless Telephone users are provided with high-quality mobile voice communications throughout the workplace. The NetLink 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 and SX-200 ICP VoIP solutions. The NetLink 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 NetLink 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 NetLink 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 NetLink i640 Wireless Telephone. 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.
