NetLink SVP Server (within IP environments)
2. NetLink SVP Server Overview
The NetLink 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 NetLink
Wireless Telephones are intercepted by the NetLink SVP Server and encapsulated
for prioritization as they are routed to and from an IP telephony server.
2.1 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.
NetLink 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
NetLink SVP Server.
2.2 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 section 7.3
2.3 The Timing Function
NetLink 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.
Software Version
.
2.4 Internal Gatekeeper
A gatekeeper is required in certain H.323 protocol systems. The gatekeeper that
resides on the SVP Server is designed for small applications using the NetLink
Wireless Telephones under the H.323 protocol.
PN: 72-0178-01-F.doc Page 6
Page 7
SpectraLink Corporation Installation, Configuration, and Administration
NetLink SVP Server (within IP environments)
The internal gatekeeper is not designed to scale beyond the capacity of a single SVP
Server and does not provide the advanced features required for larger installations. It
has a limit of 1000 registration records.
2.5 Multiple SVP Servers/Master SVP Server
Multiple SVP Server environments are those which have more than one NetLink
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.
In a system comprised of multiple SVP Servers, a master SVP Server must be
identified. The master SVP Server must have a static IP address. The wireless
telephones and the other SVP Servers locate the master by using a static IP address,
DHCP, or DNS.
The master SVP Server performs important coordinating functions. The loss of a
non-master SVP Server does not significantly affect the operation of the remaining
SVP Servers but results in the re boot of all handsets. However, the loss of the
master SVP Server results in a loss of all communication between all of the SVP
Servers. This also means that the loss of the master SVP results in the loss of all
active calls and wireless telephones cannot check in until communication with the
master is reestablished.
2.6 Multiple NetLink 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.
NetLink SVP010 and SVP020 Server Capacity
The system capacity of the SVP010 and SVP020 is measured by number of poweredon 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.
Number of SVP
Servers
1 10 20
2 20 40
3 30 N/A
4 40 N/A
NetLink 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

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.

NetLink SVP Server (within IP environments)
2.7 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. A master SVP Server must be identified in a multiple-SVP
Server environment.
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
configuration information when installing multiple SVP Server models
across several different subnets.
IP multicast addresses are used when NetLink i640 and 8030 Wireless
Telephones are installed. This requires that multicasting be enabled on the
subnet used for the NetLink 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 NetLink SVP Server requires a Cat. 5 cable connection between its
network port and the Ethernet switch. The NetLink SVP Server autonegotiates to the type of port on the Ethernet switch and supports 10BaseT, 100Base-T, full-duplex and half-duplex port types.

2.9 System Components
NetLink e340/h340/i640 and 8000 Series 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. 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 NetLink Wireless Telephones are similar to those of wireless
data devices. Contact SpectraLink, or a certified SpectraLink distributor, for specific
information about your facility’s needs.
The NetLink system must connect to APs that utilize SpectraLink Voice Priority
(SVP). Contact SpectraLink, or a certified SpectraLink 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.
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
NetLink SVP Servers, the APs, and their associated Ethernet switch must all be on
the same “side” of the router.
NetLink SVP Server
The NetLink SVP Server manages call network traffic as detailed in this document.
Administrative computer
An administrative computer is required for setup and maintenance of the NetLink
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.

Select 1MB/2MB to limit the transmission rate between the wireless telephones
and APs. Select Automatic to allow the wireless telephone to determine its rate
(up to 11 Mb/s).
SVP-II Master
The master SVP Server must be identified in an IP system. Select one of the
following identification options:
• Statically configure the IP address of the master SVP Server in each of the
SVP Servers. Enter the IP address.
See the Overview section for an explanation of the master SVP Server.
Configuration Notes
for each brand and type.
• Statically configure the IP address of the master SVP Server in a DHCP
server and configure each of the SVP Servers to get the information from the
DHCP server. Enter DHCP. If DHCP is used, the IP address of the master
SVP Server must be configured in the DHCP server. See the wireless
telephone interface document for your IP environment for more information
about DHCP integration factors.
• Statically configure the IP address of the master SVP Server in a DNS server
and configure the each of the SVP Servers to retrieve this information from
the DNS server. Enter DNS. If DNS is used, the IP address of the master
SVP Server must be configured in the DNS server.
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 NetLink
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
PN: 72-0178-01-F.doc Page 22
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.

SpectraLink Corporation Installation, Configuration, and Administration
NetLink SVP Server (within IP environments)
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 in the H.323 protocol
environment.
Ethernet link
The SVP Server will auto-negotiate unless there is a need to specify a link speed.
System Locked
This option is used to take the system down for maintenance. The default entry
is N (No). Set it at Y (Yes) to prevent any new calls from starting. Return to N to
restore normal operation.
Maintenance Lock
The system automatically sets this option to Y (Yes) after certain maintenance
activities that require reset, such as changing the IP address. Maintenance Lock
prevents any new calls from starting. Note that the administrator cannot change
this option. It is automatically set by the system. Reset the system at exit to clear
Maintenance Lock.
Inactivity Timeout (min)

QoS Configuration
DSCP tags set packet priorities for QoS.
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. 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 IP 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.
When forwarding packets, the SVP Server shall always overwrite 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. (Please see table on next
page.)
• If both Administration and the Traffic Class setting is Default, the
Default value as shown in the table below will be used.
• If Administration is set at any number (Value X) other than Default, that
setting (
PN: 72-0178-01-F.doc Page 24
Value X) it will override the Default value of the Traffic Class.
Page 25
SpectraLink Corporation Installation, Configuration, and Administration
NetLink SVP Server (within IP environments)
• If any of the Traffic Class settings are set at any value (Value Y) other
than Default, that setting (Value Y) will override the Administration
setting.

5. 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.
Adding an SVP Server
A new SVP Server is detected within two seconds of being added to the system
(booted/configured/connected). When detected, any wireless telephone not active in
a call will immediately 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
be forced to reboot and check in again.
Removing an SVP Server
When an SVP Server is removed from the system it is detected within two seconds.
Wireless telephones not in calls are immediately forced to reboot and check in again.
For wireless telephones active in calls, two possible scenarios can occur. If the SVP
Server that was removed was providing the "gateway" function for the wireless
telephone, then the call is lost and the wireless telephone is forced to check-in again.
If the SVP Server that was removed was providing the "timing" function for the call,
the call will switch to the SVP Server that should now provide the "timing" function.
Note that during the two seconds while the loss of the SVP Server is being detected,
the audio for the call will be lost.
Changing the Master SVP Server
In the event the master SVP Server loses communication with the network, the
wireless telephone system will fail. All SVP Servers will lock, All calls will be lost,
and no calls can be placed. Therefore, if the master SVP Server needs to be
replaced, be sure the system can be brought down with minimal call interruption. Be
sure to reset all SVP Servers after the master has been replaced. If the IP address of
the master is changed, it must be changed in all SVP Servers.

6. Software Maintenance
The NetLink SVP Server uses proprietary software programs written and maintained
by SpectraLink Corporation. The software versions that are running on the system
components can be displayed via the System Status screen.
You may obtain information about software updates from SpectraLink or its
authorized dealer.
At startup the NetLink 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
NetLink SVP Server will download the version in the TFTP location. See the
Configuration and Administration
information about using TFTP.
Software Updates
Lock the NetLink 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.
