1. A bandwidth control system in a communication device for performing communication in an ATM (Asynchronous Transfer Mode) scheme, comprising:

  • a transceiver for transmitting and receiving ATM cells to and from another communication device through a link;

    a transmission bandwidth controller for making a decision as to whether it is possible to allocate a requested transmission bandwidth for requested data transmission through the link by referring to a bandwidth management table; and

    a signaling controller for enabling a UNI (User-Network Interface) signaling procedure based on a result of the decision of transmission bandwidth allocation, wherein if it is possible to allocate the requested transmission bandwidth, the signaling controller produces a SETUP message for making a request for establishing a virtual channel having the requested transmission bandwidth in the link, and starts the UNI signaling procedure, and if it is not possible to allocate the requested transmission bandwidth, the signaling controller stops the UNI signaling procedure.
