Networking Philosophy
Owing to the system's sophisticated networking options, it is possible to set up a
whole range of private networks (PISN). Homogeneous networks exclusively with
PBXs of the Ascotel system family are as easily implemented as heterogeneous
networks with a mix of systems and PBXs by other manufacturers.
The system's networking philosophy is based on the assumption that the user
does not need any prior knowledge of the network topology. He can use the avail-
able features always in the same way, regardless of whether and how he is net-
worked.
