Overview
3.1 System
Architecture
The NetLink Telephony Gateway and NetLink Wireless Telephone are SpectraLink's
wireless LAN-based telephony products. NetLink products operate in the 2.400-2.483
GHz unlicensed band, using either the frequency hopping (FH) or direct sequence (DS)
spread spectrum technology which is compatible with the IEEE 802.11 wireless LAN
standard. There are two models of the NetLink Telephony Gateway – an 8-line model
and a 16-line model.
NetLink Wireless Telephones operate as clients on the wireless LAN, alongside other
mobile 802.11 devices. Wireless LAN fixed radios, called access points (APs), receive
IP voice packets from Wireless Telephones and forward them to the NetLink Telephony
Gateway over the Ethernet LAN. The Telephony Gateway connects to the host telephone
switch using digital or analog line interfaces. Using SpectraLink’s exclusive LinkPlus
digital interface technology, Wireless Telephones are able to emulate proprietary digital
telephone sets, making advanced switch features such as multiple line appearances and
display features available to mobile users.
Up to forty NetLink Telephony Gateways may be connected to the LAN for a maximum
capacity of 640 NetLink Wireless Telephones. When more than four NetLink Telephony
Gateways are installed, the NetLink SVP Server must also be installed to manage the
increased load.
