1. A communication method comprising:
- receiving information associated with a user communication into a processing system;
processing the information in the processing system to select an identifier;
generating a message containing the identifier;
transmitting the message from the processing system;
receiving the message into an interworking unit;
receiving the user communication into the interworking unit from a DS0 connection;
in the interworking unit, converting the user communication into an asynchronous communication with the identifier in a header in response to the message; and
transferring the asynchronous communication from the interworking unit.

Abstract
The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates new signaling that identifies the selection and transfers the new signaling to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the new signaling.
