Abstract
A method of integrating the switching of voice and data between terminals connected to switch adapters. The switching of voice (or more generally synchronous signals) is accomplished by grouping voice samples in a first adapter and bound for the same destination or second adapter into a frame. Connections are then established between the two adapters and the frame is transmitted therethrough. A duplex method can also be set up by transmitting in both directions at the same time once a dual connection between the first and second adapter is established. Hence, a second group of voice samples bound for the first adapter is also formed ina frame. The two frames are then transmitted simultaneously in opposite directions through a dual connection in the switching matrix. Data is switched by storing data in respective memories of respective adapters, wherein each respective memory corresponds to a particular adapter to which the data stored therein is to be sent.
