摘要
PURPOSE: A line card using a network processor in a small-sized ATM exchange is provided to use a network processor while using a switch fabric of a small-sized exchange without using a CSIX(Common Switch Interface) of the network processor, thereby improving the performance of the line card by using the network processor. CONSTITUTION: A port used as a physical interface with the exterior is separated into a substantial physical interworking interface and an inner switching fabric interworking interface, without using a CSIX switching interface supplied from a network processor. The inner switching fabric interworking interface is used as an interface requested by a UTOPIA2 interface system, and is interworked with an inner switch. An outer packet is switched in an inner switching facility of the network processor through an outer interworking port. The switching fabric is transmitted through the inner switching fabric interworking interface.
