Abstract

The device (1) essentially consists of an adapter comprising a centralised unit (5) tasked with manipulating ATM flows and managing access requests, and specialised modules (31... 3k...3n) which allow direct access to the ATM network by, for instance, a satellite network or a service (21... 2k...2n). The centralised unit (5) dynamically allocates the available band on the ATM network access resources according to the access requests by the interface towards the outside world, by handling individual requests as separate connections.
