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.

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.

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

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.
