WLAN IP Telephony Installation and Configuration
SpectraLink Voice Priority (SVP) is the QoS mechanism implemented on the
wireless handsets and APs 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 and with minimum delay. SVP is fully compliant with the IEEE
802.11 and 802.11b standards.
Each subnet where the wireless handsets will operate requires at least one
WLAN IP Telephony Manager 2245. One unit can process 80 simultaneous
calls. If greater capacity is required, multiple units can be used in a master-
slave arrangement.
WLAN Application Gateway 2246
The WLAN Application Gateway 2246 is an optional device that enables
third-party applications to communicate directly with up to 10,000 wireless
handsets. The WLAN Application Gateway 2246 is connected to the LAN
Ethernet switch through an RJ-45/CAT5 cable.
For more information on the WLAN Application Gateway 2246, refer to
Appendix A: “WLAN Application Gateway 2246” on page 155.
A WLAN Application Gateway 2246 supports 64 to 10,000 wireless
handsets, depending on the model of Gateway, as listed in Table 2.
