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.

Multiple SVP Servers
Multiple SVP Server environments are those which have more than
one SVP Server. Up to 16 SVP Servers may be installed in any one
subnet.
The Timing Function
In the SpectraLink Gateway environment, SVP Servers provide the
"timing" function for active calls. In multiple SVP Server
environments, the active calls are distributed across the SVP Servers.
The number of active SVP Servers is determined dynamically.
Whenever SVP Servers are added to or removed from the system, the
distribution of the "timing" function for active calls is affected.
The addition of an SVP Server is detected as soon as the new SVP
Server is up and running. The new SVP Server will immediately start
providing the “timing” function for the appropriate wireless
telephones. The user should not detect any change. The removal of an
SVP Server is detected within one minute. During this time, any
wireless telephone that was using the SVP Server that was removed
will be affected. If the wireless telephone was not in a call, it may lose
contact with its Gateway, resulting in a check-out/check-in sequence.
If the wireless telephone was in a call, the audio will be lost and the
call will be dropped.

SpectraLink 8000 SVP Server Capacity
The table below shows the capacity of SpectraLink 8000 Telephony
Gateways in a multiple SVP Server environment. The table shows the
total possible calls at 100% active calls. However, since it is unlikely
that all handsets will be in use at the same time, the table then
analyzes the number of handsets that could be installed in any given
system where 15%, 25% or 50% of the handsets are in active calls at
any one time. The calculations are not linear due to the Erlang1
calculation for telephony traffic. The possible installed handsets
figures are approximate and meant as a guideline and not as an
absolute recommendation for any facility.

1An Erlang is a unit of telecommunications traffic measurement. Strictly speaking, an Erlang represents the
continuous use of one voice path. In practice, it is used to describe the total traffic volume of one hour.
Erlang traffic measurements are made in order to help telecommunications network designers understand traffic
patterns within their voice networks. This is essential if they are to successfully design their network topology and
establish the necessary trunk group sizes.
Erlang traffic measurements or estimates can be used to work out how many lines are required between a telephone
system and a central office (PSTN exchange lines), or between multiple network locations.
Please visit www.erlang.com for additional information.

Notes on System Configuration
Wireless telephones cannot roam with uninterrupted service
between subnets unless specific LAN components are present.
Certain AP/Ethernet switch combinations establish a layer-2 tunnel
across subnets that enables the handsets to roam. Without this
capability, any call in progress will be dropped when the user
moves out of range and the handset must be power cycled in order
to resume functionality in the new subnet area.
Please see Deploying Enterprise-Grade Wi-Fi Telephony for
detailed configuration information when installing multiple SVP
Server models across several different subnets.
Subnets are not recommended in SpectraLink 8000 Telephony
Gateway environments.
IP multicast addresses are used when SpectraLink i640 and 8030
Wireless Telephones are installed. This requires that multicasting
be enabled on the subnet used for the SpectraLink 8000 Wireless
Telephones, SVP Server, and Telephony Gateways.
Routers are typically configured with filters to prevent multicast
traffic from flowing outside of specific domains. The wireless LAN
can be placed on a separate VLAN or subnet to reduce the effects
of broadcast and multicast traffic from devices in other network
segments.
The SVP Server requires a Cat. 5 cable connection between its
network port and the Ethernet switch. The SVP Server auto-
negotiates to the type of port on the Ethernet switch and supports
10Base-T, 100Base-T, full-duplex and half-duplex port types.
