SpectraLink 8020/8030 Wireless Telephone
The SpectraLink 8020 Wireless Telephone is a lightweight, durable
handset specifically designed for mobile workplace use. The SpectraLink
8030 Wireless Telephone has the same features and function, but in a
more durable design with and includes push-to-talk capability.
Like a wired desk phone, the handset can receive calls directly, receive
transferred calls, transfer calls to other extensions, and make outside and
long distance calls. The Wireless Telephones can only be used on-
premises within the WLAN coverage area with the local SIP call server.
SpectraLink 8000 SVP Server (required when using
SVP)
As described earlier, the SVP Server is a Polycom wired LAN device
that is required when using SpectraLink Voice Priority for QoS.
Access points
Enterprise-grade Wi-Fi access points provide the connection between
the wired LAN and the wireless LAN. VIEW Certified 802.11a/b/g/n
APs must be positioned in all areas where Wireless Telephones will
be used to ensure seamless radio coverage. The number, type and
placement of access points will affect the coverage area and capacity
of the wireless system. Careful planning of the WLAN is necessary to
ensure good voice quality. See the Best Practices Guide for Deploying
SpectraLink 8020/8030 Wireless Telephones for additional guidance.
APs must be properly configured to support the corresponding QoS
and security methods selected for the handset.
Ethernet switch
One or more Ethernet switches interconnect multiple network
devices, including the SpectraLink 8000 SVP Server (if used for QoS),
the proxy server(s), wired IP phones, TFTP Server, RADIUS
authentication server (if using WPA2 Enterprise) and WLAN access
points. Enterprise Ethernet switches provide the highest performance
