Abstract:
1. Method for connecting conventional analog and ISDN subscribers to a switching system, with the subscriber signaling between a subscriber terminal device (TNE) and the switching system being transmitted, packet-based, via a network and with a plurality of such subscribers being assigned in each case to a common set of peripheral devices (PE) of the switching system, characterized in that, at least one peripheral adaptation device (PAE) is provided, that is arranged in the periphery of the switching system and is used for the adaptation of the messages used on the interface between the subscriber terminal device (TNE) and peripheral adaptation device (PAE) serves the requirements of the set of peripheral devices (PE) assigned to the TNE port, software functions for dealing with failures in the subscriber terminal device (TNE) of at least one peripheral adaptation device (PAE) and the associated peripheral devices (PE) of the switching system are provided, due to the interaction of these software functions for dealing with failures the alternative routing and restoration of failed peripheral devices (PE), peripheral adaptation devices (PAE) and communication paths to subscriber terminal devices (TNE) are controlled.
