In the following overview ISDN supplementary services are categorized as follows:
• Identification services
• Connection services
• Rerouting services
• Call charge services
• Other services
As a rule network interfaces are wired as a point-to-point connection (P-P). However,
the point-to-multipoint (P-MP) connection type is also possible. Not all ISDN supple-
mentary services are provided by network providers on both connection types or sup-
ported by the communication server.
