SpectraLink 8000 SVP Server Overview
The SpectraLink 8000 SVP Server is an Ethernet LAN device that
works with access points (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 an IP telephony server.
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
IEEE 802.11b standards.
PN: 1725-36033-001_G.doc 7
SpectraLink 8000 SVP Server: Administration Guide for SIP
SpectraLink 8000 SVP Server Models
The SVP Server is available in three models. Which model is selected
for your facility depends on current and expected capacity. All SVP
Servers within a subnet must be the same model type.
• SVP100: Serves 80 calls simultaneously.
• SVP020: Serves 20 powered-on handsets.
• SVP010: Serves 10 powered-on handsets.
See the following capacity tables for multiple SVP Server system
capacities.
All SVP Server models are installed, configured and administered
according to the instructions in this document. The model information
is available on the Software Version screen. See Chapter 6
Troubleshooting via System Status Menu, section Software Version.
The Timing Function
SVP Servers provide the connection or "gateway" to the IP PBX for the
wireless telephones and the "timing" function for active calls. This
"gateway" function is 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.
Multiple SVP Servers
Multiple SVP Server environments are those which have more than
one SVP Server. Up to four SVP010 models or up to two SVP020
models may be installed in any one subnet. Up to 16 models of
SVP100 Servers may be installed in any one subnet. All SVP Servers
must be in the same subnet.
When more than one SVP Servers are installed, the wireless telephone
load is balanced across the available Servers, both for the
communication path between the SVP Server and the wireless
8 PN: 1725-36033-001_G.doc
SpectraLink 8000 SVP Server Overview
telephones, and between the SVP Server and the PBX (or other far-end
device).
SVP Server availability
A SpectraLink handset registers to a single SVP Server the first time it
is powered on. Once the handset has contacted this Registration
Server, it obtains a list of all SVP Servers in the system. The handset
then maintains this list in non-volatile memory and updates it only
when rebooted. When a handset later attempts to check in and cannot
contact the ordained Registration Server, it will then fall back to its list
of other Servers and attempt to check in elsewhere. After the handset
has successfully checked into the system once, it never requires that
the Registration Server be present unless the handset is reconfigured
back to factory defaults, or the entire system of SVP Servers is
changed out. See section Swapping/Adding/Deleting SVP Servers.
Registration Server identification
The handsets identify the SVP Server in three possible ways. These
are outlined in the Administration and Configuration document for the
handset model(s) and the IP protocol being used in your facility.
Essentially, the SVP Server can be identified by a static IP address in
the Admin menu, by a DHCP option 151 specification, or by a DNS
query of “SLNKSVP2”. The address found identifies the Registration
Server.

Multiple SVP Server Capacities
The system capacity of each SVP Server model is shown in the tables
below. Note that SVP Server models may not be combined within one
subnet.
SpectraLink SVP010 and SVP020 Server capacity
The system capacity of the SVP010 and SVP020 is measured by
number of powered-on handsets. If this number exceeds the
maximum, the handset that cannot be served will display an error
and will not connect to the SVP Server. Other handsets will not be
affected.

SpectraLink SVP100 Server capacity
The capacity of the SVP100 Server is determined by active calls. The
table below shows the capacity of an IP gateway 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 10%, 15% or 20% of
the handsets are in active calls at any one time. The calculations are
not linear due to the Erlang
1
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 SIP
Notes on System Configuration
In an IP system using subnets to differentiate telephony areas, each
subnet must have its own APs. Each subnet may require an SVP
Server to maintain voice quality, but this depends on traffic volume
and router capacity.
Multiple SVP Server environments are those which have more than
one SVP Server.
SVP Server models may not be combined within one subnet. More
than one SVP Server model type may be used within a facility if
installed on different subnets.
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 Pr actices for Deploying Enterprise-Grade Wi-Fi
Telephony for detailed configuration information when installing
multiple SVP Server models across several different subnets.
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 through the WLAN coverage area. The wireless telephones
are to be used on-premises; they are not cellular or satellite phones.
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.)
Access points
Supplied by third party vendors, APs 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 8000 System must connect to APs that utilize
SpectraLink Voice Priority (SVP). Contact Polycom, or a certified
Polycom distributor, to verify that your AP and its software version
are supported.
Ethernet switch
A component in the wired Ethernet LAN infrastructure. Switches
interconnect multiple network devices, including APs and other
components. Ethernet switches are required to provide the higher
performance network connections needed to handle combined voice
and data traffic.
14 PN: 1725-36033-001_G.doc
SpectraLink 8000 SVP Server Overview
Router
A 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 SVP Servers, the APs, and their
associated Ethernet switch must all be on the same “side” of the
router.
SpectraLink 8000 SVP Server
The SVP Server manages call network traffic as detailed in this
document.
Administrative computer
An administrative computer is required for setup and maintenance of
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.
TFTP server
Required in an IP system to distribute software to the wireless
telephones and SVP Server. May be on a different subnet than the IP
gateway, IP telephony server, and APs.

SpectraLink 8000 SVP Server: Administration Guide for SIP
First Alias IP Address/Last Alias IP Address
The SVP Server uses an IP address when acting as a proxy for the
wireless telephone. Therefore, one alias IP address is required for
every installed Wireless Telephone. These IP addresses must be
entered as a range and must be assigned solely for this purpose.
When multiple SVP100 Servers are installed, a different range must be
configured in each SVP Server. In determining how many addresses
to configure per SVP Server, use this formula: (# of handsets / # of
SVP Servers) + 30%. This formula will accommodate the possibility of
unequal distribution of handsets among the available SVP Servers.
All alias addresses must be on the same subnet as the SVP Server
and cannot be duplicated on other subnets or SVP Servers. There is
no limit to the number of addresses that can be assigned, but the
capacity of each SVP Server is 500 wireless telephones.
Alias IP Addresses are not necessary in Cisco systems.
Enable H.323 Gatekeeper
In certain H.323 protocol systems, the SVP Server may function as a
gatekeeper. Enter Y to have the SVP Server function as the gatekeeper

Check-in throttling
The check-in throttling option regulates the number of handsets that
can check-in simultaneously. The error

QoS Configuration
DSCP tags set packet priorities for QoS.
Configuring the SpectraLink 8000 SVP Server
DSCP Tag
DSCP (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
• RTP traffic is the audio traffic to the IP PBX. It requires voice
quality.
• PBX traffic is not audio to the PBX.

SpectraLink 8000 SVP Server: Administration Guide for SIP
When forwarding packets, the SVP Server overwrites the received DSCP value. The
final DSCP tag for packets in each of the traffic classes are assigned a DSCP value
based on the following rules and per the table below.
• Packets are tagged with the corresponding Traffic Class value entered in the
QoS Configuration menu if the value for the Traffic Class is set to something
other than Default.
• Otherwise, packets are tagged with the Administration Traffic Class value (the
first item in the QoS Configuration Menu) if the corresponding Traffic Class is set
to Default and the Administration Traffic Class value is set to something other
than Default.
• Finally, packets are tagged with the Default value of the corresponding Traffic
Class if both the corresponding Traffic Class and the Administration Traffic Class
values are set to Default. The following table lists the Default values for the
DSCP tags.
Traffic Class Default
Administration Priorit y Low 0
WT (In call) Priority High 4
WT (Standby) Priority Med 0
RTP Priority High 4

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 and calls
may be lost. If the removal of the SVP Server is intentional, the
administrator should lock and idle the system prior to removing an
SVP Server.
Load balancing enables a locked SVP Server to distribute idle
handsets to other SVP Servers in the cluster. Existing calls will not
be interrupted and the SVP Server will become idle once all calls
are ended and idle phones are transferred to another SVP Server.
Adding an SVP Server
A new SVP Server is detected within two seconds of being added to
the system (booted/configured/connected). When detected, wireless
telephones not active in a call will gradually be forced to reboot and
check in again. Any wireless telephone in a call will immediately
switch to the SVP Server that should provide its "timing" function.
This switch should not be noticeable to the user since it is similar to a
normal handoff between APs. When the wireless telephone ends the
call, it will eventually be forced to reboot and check in again. Only a
few handsets at a time are rebooted to prevent excessive check in
traffic on the network. Handsets scheduled to be rebooted can still
make calls and will be rescheduled for reboot when the call is ended.
Removing an SVP Server
The preferred method for removing an SVP Server from an active
system is to first lock the SVP Server. When an SVP Server is locked
for removal from the system, load balancing enables the locked SVP
Server to distribute idle handsets to other SVP Servers in the cluster.
Active calls will not be interrupted. The locked SVP Server will
PN: 1725-36033-001_G.doc 37
SpectraLink 8000 SVP Server: Administration Guide for SIP
become idle once all calls are ended and idle handsets are registered
to other SVP Servers. Once all handsets have been moved---as
evidenced by the number of
screen---the idle SVP Server may be unplugged and removed from
the system.
During this process, there is a short period where a handset registered
on a locked SVP Server may attempt to initiate a call before it is reregistered to another SVP Server. In this case, if there is an unlocked
SVP Server in the cluster, the SVP Server will tell the handset to
reboot. As it reboots, the handset will check-in with an available SVP
Server and the user may then start a call. Handsets registered on
unlocked SVP Servers are not affected.
Of course if a system only has one SVP Server, no calls will be
possible until the removed SVP Server is replaced.
SVP Server Failure
Telephones in Use on the Network Status
If an SVP Server becomes unable to manage calls or fails, any handset
registered to that SVP Server loses service (and any calls) and will
reboot within 30 seconds. After rebooting, the handset will register
with another SVP (if there is one available) and be able to make new
calls. Handsets not registered on the failed SVP may experience a few
seconds of disruption in audio but are otherwise unaffected.

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. See the Configuration and Administration document for your
vendor’s IP system for more information about using TFTP.

System
Software Updates
Lock the SVP Server in the SVP-II Configuration screen prior to updating
the software. In multiple SVP Server systems, all SVP Servers must be
locked and upgraded at the same time.
Downloads for the SVP Server are available from
http://www.polycom.com/usa/en/support/voice/wifi/spectralink_8000_svp_server.html.
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(s).
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.
