ELEPHONY SERVER SOFTWARE
The individual license is used for ports, for example, the analog
extension. Each individual license is defined with a maximum
number of allowed licenses.
Any object that requires licensing seizes a license when the object
is initiated. The license is released when the object is removed from
the system.
• System license
The system license is used for optional system facilities, such as
network services. A system license can have two values: service
available or service not available.
The license information is stored and later checked when the
optional system facility is initiated.

6.4.7.1 Supervisory Functions on System Level
Server/Gateway Supervision
The server/gateway supervision function has the following purposes:
• Supervise the start state and communication capabilities
This is done to make sure that all servers start up correctly and that
inter-server communication is working.
• Build up, distribute, and maintain system tables
This includes the Common Function Table (CFT). The CFT speci-
fies the server in which the different common function programs are
running.
Cross Address Check
For some applications within the system, connections between data
areas in different program units are built up. If the system consists of
several servers, it is most likely that these connections are set up
between program units in different servers.
