Title: Testing method for asyncronous transfer mode adaptation layer chip
Inventor: KIM YEONG HO

Filed: 2000-11-07
Abstract: PURPOSE: A method for testing an asynchronous transfer mode adaptation layer chip(AALx ASIC) is provided to verify a normal operation of an AALx chip by recording data in a Tx_FIFO and an Rx_FIFO or receiving response data of the AALx chip with respect to a process of the recorded data using the Tx_FIFO and the Rx_FIFO at an external of an AALx ASIC without an external device as an additional ATM cell generator. CONSTITUTION: A host programs 53-byte data values of a proper AALx pattern including a wanted VPI(Virtual Path Interface) and VCI(Virtual Channel Interface) for a test and records the data values in a Tx_FIFO successively(301). An AALx ASIC receives a value recorded in the Tx_FIFO by the host(302) and converts the received data value of the AALx pattern into a wanted PCM value or a payload value(303). If the PCM value or the payload value is looped in the last terminal of the AALx ASIC, a pre-converted PCM value or a pure payload value is converted into an AALx pattern adding a wanted VPI and VCI pattern again in a receiving portion of the AALx ASIC and records the value in an Rx_FIFO(304). When one cell is recorded in the Rx_FIFO, the host reads the value recorded in the Rx_FIFO and decides whether the read value is identified with the value of the Tx_FIFO, thus an H/W(Hard Ware) and an F/W(Firm Ware) of the AALx ASIC are verified(305).
