Private Network with ASB 150 02 and ASB 501 sytems
The following example shows a private network with ASB 501 as main node and ASB 150 02 as end nodes ("branch
offices"). Standard QSIG and proprietary services are supported via leased and / or switched lines.
Example:
The symbols mean 1 or more Q-/T-interfaces.
All gateway and main node functionalities are provided by ASB 501. The ASB 150 02 nodes can have own public
network access for own public traffic, so as not to overload connections with the main node. Furthermore, it is also
possible to connect the ASB 150 02 end nodes (dotted lines) directly, to prevent overloading of connections to the
main node by traffic carried only between the end nodes.
