SpectraLink 8000 SVP Server: Administration Guide for SIP

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 Erlang1 calculation for telephony traffic. The

1An 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.
