An ATM transit switch is proposed based on direct sequence optical code division multiple access technique. No buffering is necessary to facilitate the switching. Code conversion is used instead to emulate the switching function. The switch not only provides asynchronous access to the users but also has a limited capability of dynamic bandwidth allocation. It is free from timing jitters and switching delay is significantly reduced. A look-up table is employed in the switching and updated through network management functions. The switch provides a new approach to asynchronous cross-connection in the ATM core network. The performance of the new switch is evaluated by a set of prime codes and modified prime codes.
