The distributed architecture switch of the invention provides a scalable, flexible switching device to route telephone calls and other data (e.g., frame relay, ISDN) over an asynchronous transfer mode (ATM) network. The switch includes multiple service modules that can be geographically disparate and function as a single switching device. The multiple service modules are coupled to a system controller that controls the service modules and passes messages between the service modules.

1. A method for jointly facilitating a telephone call by a first device and a second device, the method comprising:communicating routing information between the first device and the second device using a first signaling protocol and a first network; allocating an available virtual channel in a cell based bearer connection between the first device and the second device established using a second cell based signaling protocol and over a second network, with said cell based bearer connection having a predetermined plurality of fixed size virtual channels for facilitating up to a corresponding plurality of telephone calls, and cells of said cell based bearer connection being transmitted continuously in accordance with said second cell based signaling protocol as long as at least one of the virtual channels is allocated to facilitate a telephone call; and facilitating said telephone call through said allocated virtual channel of said cell based bearer connection.
