Abstract

The present invention present a telecommunication system comprising a circuit switch (1), through which variable bit rate traffic is sent utilising a circuit-switch connection (9). The connection (9) is established between an interworking unit (6) and a pooled functionality device (8) of the circuit switch (1), and may be of a narrow band, wideband or broadband type. Variable bit rate packets received in the interworking unit (6) are mapped to an internal format and sent through the connection (9). Any signalling messages are terminated and used for handling the connections (9) and, if the connection (9) is of a wideband or broadband type, reserving channels within the connection (9) for different calls or sessions. The variable bit rate traffic received at the pooled functionality device (8) is typically demultiplexed according to the channel number and synchronized, which transfers them into a constant bit rate fashion. Similarly, constant bit rate traffic may be packetized and sent over the connection (9) to the interworking unit (6) according to the internal variable bit rate format. ATM networks and Internet networks are two particularly suitable variable bit rate networks for such solutions.
