SpectraLink Overview
The SpectraLink 8000 Telephony Gateway provides telephone
functionality to SpectraLink Wireless Telephones over a wireless local
area network (LAN). The installation process connects the Gateway to
an existing host telephone system and LAN. The configuration
process covers downloading current software, setting network
parameters, setting Gateway parameters, assigning wireless
telephones to the lines controlled by the Gateway, and establishing
feature programming. Maintenance covers adding and deleting
handsets, upgrading software, etc. The Troubleshooting chapter
provides directions for analyzing system functioning via the
System
Status menu.
System Architecture
The SpectraLink 8000 Telephony Gateway and SpectraLink Wireless
Telephone are Polycom's wireless LAN-based telephony products.
SpectraLink 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 SpectraLink 8000
Telephony Gateway: an 8-line model and a 16-line model.
Note that the 16-port Gateway and the 8-port Gateway are installed
and configured identically. Both support eight simultaneous calls.
However, the 8-port Gateway will be limited to eight line interfaces.
SpectraLink 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
handsets and forward them to the SpectraLink 8000 Telephony
Gateway over the Ethernet LAN. The Telephony Gateway connects to
the host telephone switch using digital or analog line interfaces. Using
Polycom’s exclusive LinkPlus digital interface technology, handsets
are able to emulate proprietary digital telephone sets, making
advanced switch features such as multiple line appearances and
display features available to mobile users.
