SpectraLink 8000 SVP Server
Overview
The SVP Server is an Ethernet LAN device that works with APs to
provide QoS on the wireless LAN. Voice packets to and from the
SpectraLink 8000 Wireless Telephones are intercepted by the SVP
Server and encapsulated for prioritization as they are routed to and
from the SpectraLink 8000 Telephony Gateway.
One or more SVP Servers are required in systems with five or more
SpectraLink 8000 Telephony Gateways. In systems with four or fewer
SpectraLink 8000 Telephony Gateways, the SVP Server is not required
because SVP is handled within the SpectraLink 8000 Telephony
Gateway(s).
SpectraLink Voice Priority (SVP) and
Quality of Service
SpectraLink Voice Priority (SVP) is the SpectraLink quality of service
(QoS) mechanism that is implemented in the wireless telephone and
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 delay. SVP is fully compatible with the
IEEE 802.11b standard.
SpectraLink 8000 Wireless Telephones support basic WMM (Wi-Fi
Multimedia) if also supported by the AP as part of the 802.11e
protocol. If the AP supports WMM, the wireless telephone
automatically discovers and uses it. WMM does not replace the SVP
Server.
