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
Page 9
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:

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.

2.7 System Components
• NetLink e340 and i640 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 NetLink Telephony Gateway or IP 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.)
The NetLink e340, h340 Wireless Telephone is a lightweight, durable handset specifically designed for mobile workplace use within a facility. The NetLink i640 Wireless Telephone offers a durable design with push-to-talk functionality.
NetLink Wireless Telephones can operate on an 802.11b wireless network and can operate at a transmission rate of up to 11Mb/s.
• NetLink Telephony Gateway – serves as the connecting point, or gateway, between
the LAN and the existing telephone system. One or more NetLink Telephony Gateways are typically installed in the telephone equipment room. Each NetLink Telephony Gateway supports up to 16 telephone lines and Wireless Telephones. Up to 40 NetLink Telephony Gateways can be connected to the LAN to support additional telephone lines. If five or more NetLink Telephony Gateways are connected to the LAN, a NetLink SVP Server must be installed to handle the increased call volume.
SpectraLink offers digital NetLink Telephony Gateways that work with the digital ports on most common brands of telephone systems (PBX or key systems). We also offer an analog NetLink Telephony Gateway that works with telephone systems (CO, PBX, or Key Systems) with analog (loop start) ports.
• Access Points – supplied by third party vendors, access points provide the connection between the wired Ethernet LAN and the wireless (802.11) LAN. Access points (AP) must be positioned in all areas where Wireless Telephones will be used. The number and placement of access points will affect the coverage area and capacity of the wireless system. Typically, the requirements for use of NetLink Wireless Telephones are similar to that 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 access points 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 access points and NetLink Telephony Gateways. Ethernet switches are required to provide the higher performance network connections needed to handle combined voice and data traffic.
Part Number: 72-0178-00-J.doc Page 14
Page 15
NetLink SVP Server
• Router – 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 Telephony Gateways, 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. It is a required component to utilize the 11Mb/s maximum transmission speed available in the NetLink Wireless Telephone. It is required in any system when five or more NetLink Telephony Gateways are connected to the LAN. With 40 NetLink Telephony Gateways cabled together, the NetLink SVP Server supports a maximum of 640 telephone lines and 120 simultaneous Wireless Telephone calls.
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 or no delay. SVP is fully compliant with the IEEE 802.11 and 802.11b standards.
• Administrative computer – Required for setup and maintenance of the NetLink Telephony Gateway and 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.
• 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.

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. Whenever an SVP Server is added to the system, the change is seamless and does not affect Wireless Telephone calling functionality.
5.1 IP System
Adding an SVP Server
In the IP PBX environment, 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 check-out 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 access points. When the Wireless Telephone ends the call, it will be forced to checkout and checkin 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 checkout and checkin 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 checkin 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 and all calls will be lost and no calls will be able to 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.

NetLink SVP Server
5.2 NetLink Telephony Gateway System
In a NetLink 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.
There is no master SVP Server in a NetLink Telephony Gateway environment.

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.
SpectraLink or its authorized dealer will provide information about software updates and how to obtain the software (for example, downloading from a web site).
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 Setup and Administration document for your vendor’s IP system for more information about using TFTP.
6.1 Software Updates
After software updates are obtained from SpectraLink, they must be transferred to the TFTP location in the LAN to update the code used by the NetLink SVP Server.
Lock the NetLink SVP Server in the SVP-II Configuration screen prior to updating the software.
Note that locking the NetLink SVP Server will prevent new calls from starting. All calls in progress will be terminated when the NetLink SVP Server is reset.
