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.

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.

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 in the H.323 protocol environment.

The SVP Server will auto-negotiate unless there is a need to specify a link speed.
Check-in throttling
The check-in throttling option regulates the number of handsets that can check-in simultaneously. The error caused by a massive check-in that has overwhelmed the server. If persisting, throttling may be raised. However, a setting that is too high may slow check-in performance. The option allows for a setting from 0 to 4, with 0 being the least amount of throttling and 4 being the most. Consult with Customer Support for help in determining if throttling is advised for your system.

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

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 PBX Priority Med 0 Inter-SVP2 Priority Med 0
Default DSCP settings will mark traffic for Best Effort handling under normal circumstances. Please consider changing these values based on the recommended QoS settings from your network hardware manufacturer to achieve prioritization for your voice traffic.

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.
