摘要：An access control unit to interface one ATM core network and at least onebidirectional access network is provided, which includes means to perform ATM signallingand resource management to provide dynamically adjustable ATM switched virtualconnections (SVC) for subscribers connected to the access network. The central access
control unit processes ATM signalling and resource management to enable e.g. switchedvirtual connection over HFC. During the ATM signalling phase the applications negotiatethe required resources which the central access control unit of HFC extracts. The centralaccess control unit has the ability to allow or reject a connection (SVC) setup. As soon asthe a new SVC is established the access control unit performs on the ATM layer theinstallation of the negotiated ATM connection values (VPI (virtual path identifier), VCI(virtual channel identifier), . . . ) at the different involved HFC network elements.
