SpectraLink 8020/8030 Wireless Telephone Overview
The SpectraLink 8020/8030 Wireless Telephones are mobile handsets for workplace IP telephone systems. The handsets operate over an 802.11b wireless Ethernet LAN providing users a wireless voice over IP (VoIP) extension. By seamlessly integrating into a SIP environment, handset users are provided with
The handsets 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 54 Mb/s.
In the SIP environment, the handsets support up to three proxy servers. Each handset may have five line appearances and two calls per line. Each handset may have up to 10 sets of credentials to identify itself by current user.
SpectraLink Voice Priority (SVP) and
Quality of Service
SVP is the SpectraLink quality of service (QoS) mechanism that is implemented in the handset and an access point (AP) to enhance voice quality over the wireless network. SVP gives preference to voice packets over data packets on the wireless medium, increasing the probability that all voice packets are transmitted efficiently and with minimum or no delay. SVP is fully compatible with the IEEE 802.11 standards.
The SpectraLink 8000 SVP Server is an Ethernet LAN device that works with the AP to provide quality of service (QoS) on the wireless LAN. Voice packets to and from the SpectraLink 8020/8030 Wireless Telephones are intercepted by the SpectraLink 8000 SVP Server and
