NetLink SVP Server
2. NetLink SVP Server Overview
SpectraLink Voice Priority (SVP) is the SpectraLink quality of service (QoS) mechanism that is implemented in the Wireless Telephone and access point (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 compliant with the IEEE
802.11, 802.11b, 802.11e and 802.11i standards.
The NetLink SVP Server is an Ethernet LAN device that works with the AP 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 or gateway.
NetLink Wireless Telephones support the 802.11e protocol including basic WMM™ and the optional admission control if these are in turn supported by the AP. If the AP supports WMM, the Wireless Telephone automatically discovers and uses it. WMM does not replace the NetLink SVP Server.
2.1 Multiple SVP Servers
Multiple SVP Server environments are those which have more than one NetLink SVP Server in the same subnet in order to accommodate larger systems and higher call capacity.
In a system comprised of multiple SVP Servers using an IP protocol, 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 loss of a non-master SVP Server does not significantly affect the operation of the remaining SVP Servers. 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 master is reestablished.
In a NetLink Telephony Gateway system using multiple SVP Servers, there is no “master” server.
Part Number: 72-0178-00-J.doc Page 8
NetLink SVP Server
2.2 The Timing Function
In the NetLink 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. In the IP PBX environment, SVP Servers provide both 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.
In both environments, the number of active SVP Servers is determined dynamically. Whenever SVP Servers are added to or removed from the system, the distribution of "timing" function for active calls, as well as the "gateway" function in the IP PBX environment, is affected.
In a NetLink Gateway environment, 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.
2.3 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 as explained in NetLink e340/i640 Wireless Telephone—With ITU H.323 Protocol: Setup and Maintenance.
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.

2.4 NetLink SVP Server Capacity
The NetLink SVP Server requires a Cat. 5 cable connection between its network port and the Ethernet switch. The NetLink 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.
The maximum number of calls a single NetLink SVP Server is able to handle depends on LAN factors per the following table:
Number of
Supported Calls
IP Gateway 10 80 500
NetLink Telephony Gateway 10 120 640
10Base-T 100Base-T
Multiple SVP Servers can be used in both NetLink Telephony Gateway and IP system environments.

2.5 Notes on System Configuration
In an IP system using subnets to differentiate telephony areas, each subnet
must have its own SVP Server as well as access points. This is not considered a multiple SVP Server environment since the SVP Servers are separated by the subnet architecture. Multiple SVP Server environments are those which have more than one SVP Server in the same subnet in order to accommodate a high volume of wireless telephony traffic.
Wireless Telephones cannot roam between subnets. Any call in progress will be dropped when the user moves out of range. In order to resume functionality in the new subnet area, the user must power cycle the Wireless Telephone. Once the Wireless Telephone achieves communication within the new subnet, normal functionality will return.
Subnets are not recommended in NetLink Telephony Gateway environments.
IP multicast addresses are used by the NetLink i640 Wireless Telephone system. 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.
