1. An apparatus, coupled to a communication network, for modifying a virtual path capacity in the communication network which transfers communication cells in an asynchronous transfer mode, each of said communication cells having a virtual path identifier indicative of a virtual path which said communication cell passes through, comprising:

  • means for receiving a control cell from a first line of said communication network through said virtual path and passing said control cell to a second line of said communication network along said virtual path, said control cell having control information indicative of a modification to be made to a bandwidth of the virtual path and a virtual path identifier same as that of said communication cell; and

    means for modifying a bandwidth allocated to the virtual path in accordance with the control information of said control cell.
