Abstract:
1. A method for processing ATM cells, the method comprises: receiving at a first input interface a first ATM cell that comprises a first virtual channel identifier (VCI) field and a first virtual path identifier (VPI) field; in response to receiving the first ATM cell at the first input interface, selecting a first parameter table, wherein the first parameter table is associated with the first input interface; selecting a first PHY table entry from a first PHY table to determine if the first VCI and first VPI fields of the first ATM cell belong to a first predefined group of VCI and VPI fields, wherein selecting the first PHY table entry is based upon a first PHY value from the first ATM cell, wherein the first PHY table is associated with the first parameter table; if the first VCI and first VPI fields of the first ATM cell belong to the first predefined group of VCI and VPI fields then: processing the first ATM cell without using the first VCI/VPI table if the first VCI and first VPI fields of the first ATM cell do not belong to the first predefined group of VCI and VPI fields.
