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 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

SpectraLink 8000 SVP Server Overview

PN: 1725-36033-001_G.doc 9

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.

4 40 N/A

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 Erlang1calculation for telephony traffic. The

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.
