Abstract:
A communication system for allocating a permanent virtual circuit (PVC) to a user terminal connected through an asynchronous transfer mode (ATM) network interface to an ATM network, comprising:a PVC control server connected through an ATM interface to said ATM network; a switching system disposed in said ATM network for connecting said user terminal to said PVC control server through a switched virtual circuit (SVC) according to a virtual path identifier (VPI) and a virtual channel identifier (VCI) generated by said user terminal; and an operator controlled workstation connected to said switching system for checking a state of said switching system, for generating a signal in accordance with one of acceptance and rejection of a demand of said user terminal on said PVC, and for providing said generated signal to said PVC control server upon receiving PVC demand data from said user terminal through said PVC control server, said signal generated by said operator controlled workstation being transferred through said SVC to said user terminal.
