摘要： According to the invention, each user connected to a termination (CM) of a Customer Premises Network (CPN) belonging to an ATM Virtual Private Network (AVPN) before transmitting his data with a given transmission bandwidth, sends a request to the access node through which he is connected to the public network.
The user can start the data transmission only after having received confirmation of the acceptance of his bandwidth request by all the elements of the network involved in the connection.
According to the invention all the functions for sending requests and signals to the transmission bandwidth allocations are performed at ATM level using particular ATM cells called Fast Resource Management cells (FRM).
Always according to the invention the ATM-N node examines the content of a particular field of all the ATM cells and after identification of the same as Resource Management (RM) cells addresses the same to an output link (LINK-OUT) to which a Fast Resource Management server (FRMU) is connected.

摘要： A switched telephone exchange is described that comprises a plurality of modules designed to use a connection network of the "mesh" type to implement medimum - low potential exchanges (for instance 20.000 users) or else a connection network of the centralized type - by means of adaption circuits - to implement high potential exchanges (for instance 100.000 users).
This characteristic permits the installation of medium to low capacity exchanges, which have low costs as they do not have any centralized organs, and their subsequent "conversion" into high potential exchanges when there is a large increase in user traffic.
The adaption circuits comprise parallel to serial conversion facilities (IFT) for the voice signals, line facilities (ULL), signalling processing facilities (USI) for the signalling exchanged between the individual modules of the switched exchange, serial to parallel conversion facilities (IFR) for the voice signals.
