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).
1
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.
PN: 1725-36032-001_F.doc
SpectraLink 8000 SVP Server: Administration Guide for SRP
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 Overview
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 Erlang
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.
An 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.

SpectraLink 8000 SVP Server: Administration Guide for SRP
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 Best Practices for 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 autonegotiates to the type of port on the Ethernet switch and supports
10Base-T, 100Base-T, full-duplex and half-duplex port types.

System Components
SpectraLink e340/h340/i640 and
8020/8030 Wireless Telephones
Employees can carry wireless telephones to make and receive calls as
they move throughout the building. The wireless telephones are to be
used on-premises; they are not cellular or satellite phones. They are
connected to the facility's existing telephone system and to the
SpectraLink 8000 Telephony Gateway. Just like wired telephones,
they can receive calls directly, receive transferred calls, transfer calls
to other extensions, and make outside and long distance calls (subject
to the restrictions applied in your facility.)
SpectraLink 8000 Telephony Gateway
The SpectraLink 8000 Telephony Gateway serves as the connecting
point, or gateway, between the LAN and the existing telephone
system. One or more SpectraLink 8000 Telephony Gateways are
typically installed in the telephone equipment room. Each
SpectraLink 8000 Telephony Gateway supports up to 16 telephone
lines and wireless telephones. Up to 40 SpectraLink 8000 Telephony
Gateways can be connected to the LAN to support additional
telephone lines. If five or more SpectraLink 8000 Telephony Gateways
are connected to the LAN, a SpectraLink 8000 SVP Server must be
installed to handle the increased call volume.
Polycom offers digital SpectraLink 8000 Telephony Gateways that
work with the digital ports on most common brands of telephone
systems (PBX or key systems). We also offer an analog SpectraLink
8000 Telephony Gateway that works with telephone systems (CO,
PBX, or Key Systems) with analog (loop start) ports.
Access points
APs are supplied by third party vendors. They provide the connection
between the wired Ethernet LAN and the wireless (802.11) LAN. APs
must be positioned in all areas where wireless telephones will be
used. The number and placement of APs will affect the coverage area
and capacity of the wireless system. Typically, the requirements for
use of SpectraLink 8000 Wireless Telephones are similar to those of

wireless data devices. Contact Polycom, or a certified Polycom
distributor, for specific information about your facility’s needs.
The SpectraLink system must connect to APs that utilize SVP. Contact
Polycom, or a certified Polycom distributor, to verify that your AP
and its software version are supported.
Ethernet switch
Ethernet switches interconnect multiple network devices, including
APs and SpectraLink 8000 Telephony Gateways. Ethernet switches
are required to provide the higher performance network connections
needed to handle combined voice and data traffic.
Router
The router is an optional component in the wired Ethernet LAN
infrastructure that separates a wired LAN into segments so that
network traffic is restricted to those segments that are directly
involved in the communication. Installation of a network router is
recommended in larger networks, where there may be significant
network traffic not related to the wireless LAN. A router will isolate
the wireless LAN from the associated wired LAN so that they are not
impacted by each others’ traffic. The SpectraLink 8000 Telephony
Gateways, the APs, and their associated Ethernet switch must all be
on the same “side” of the router.
PN: 1725-36032-001_F.doc
SVP Server
The SVP Server manages call network traffic. It is required in any
system when five or more SpectraLink 8000 Telephony Gateways are
connected to the LAN.
Administrative computer
An administrative computer is required for setup and maintenance of
the SpectraLink 8000 Telephony Gateway and the SVP Server. This
computer may be temporarily connected directly to the component or
to the network; a dedicated computer is not required. Some
installations use a laptop to configure and maintain system
components.

DSCP Tag
(Differentiated Services Code Point) is a QoS mechanism for setting
relative priorities. Packets are tagged with a DSCP field in the IP
header for type of service. The decimal value may be set as a number
from 0-63 and may be different for each traffic class listed on the
screen.
Administration tags set the priority for telnet, TFTP, and other
administrative traffic. Administrative traffic can have the lowest
priority because it does not require voice quality.
WT (In call) traffic requires voice quality and may be set to a higher
priority than
WT (Standby) traffic.

RTP traffic is the audio traffic to the PBX. It requires voice quality.
PBX traffic is not audio to the PBX.
Inter-SVP2 traffic is the information-passing protocol that SVP
Servers use to communicate with each other.
The final DSCP tag of traffic for packets in each of the above Traffic
Classes is governed by the logic below when SVP is used in an SRP
environment:
• If in-call and WT (In call) value is not Default then the configured
value is used. Valid range is 0-63.
• If not in-call and WT (Standby) value is not Default then the
configured value is used. Valid range is 0-63.
• Default means “shall not change value of DSCP tag”, in other
words the received DSCP value (from the Gateway) is passed
transparently.
Reset System
If this option is selected, you will be prompted to reset the SVP Server
upon exiting this screen.
The SVP Server should be reset at the end of any maintenance
procedure that requires a reset either via Maintenance Lock or
manually via Reset System.
Note that resetting the SVP Server will terminate any calls in
progress.

If desired, the password to access the SVP Server may be changed.
A password must meet the following requirements:
• It must be more than four characters, but cannot exceed 16
characters.
• The first character must be a letter.
• Numbers or letters are allowed.

Swapping/Adding/Deleting
SVP Servers
Whenever an SVP Server is removed from the system, wireless
telephones that are using the SVP Server will be affected. If the
removal of the SVP Server is intentional, the administrator should
lock and idle the system prior to removing an SVP Server. Whenever
an SVP Server is added to the system, the change is seamless and does
not affect wireless telephone calling functionality.
In a SpectraLink Gateway environment, the addition of an SVP Server
is detected as soon as the new SVP Server is 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, the wireless telephone may lose contact with its
gateway, resulting in a checkout/checkin sequence. If the wireless
telephone was in a call, the audio will be lost and the call will be
dropped.

Software Maintenance
The SVP Server uses proprietary software programs written and
maintained by Polycom Corporation. The software versions that are
running on the system components can be displayed via the
Status
screen.
You may obtain information about software updates from Polycom or
its authorized dealer.
At startup the SVP Server uses TFTP to check the software version it
is running against the version in the TFTP location. If there is a
discrepancy, the SVP Server will download the version in the TFTP
location.

System
Software Updates
Lock the SVP Server in the SVP-II Configuration screen prior to updating
the software.
Downloads for the SVP Server are available from
http://www.spectralink.com/softwareUpdates
After software updates are obtained from Polycom, they must be
transferred to the TFTP location in the LAN to update the code used
by the SVP Server.
Note that locking the SVP Server will prevent new calls from
starting. All calls in progress will be terminated when the SVP
Server is reset.
