摘要
PURPOSE: An apparatus for managing a service quality by lines in a B-ISDN(Broadband Integrated Service Digital Network) of an ATM(Asynchronous Transfer Mode) is provided to offer a better service quality by measuring a network quality of a subscriber line, storing the measured line quality index as a file and periodically transmitting it to an upper integrated quality management system. CONSTITUTION: A test cell pattern generator(200) selects a physical layer connected to an ATM exchange of a line to be measured in its quality to transmit VPI/VCI(Virtual Path Identifier/Virtual Channel Identifier) information of the line to an ATM layer processor(100), and generates a pattern of a test cell defined by ITU-T 0.191(Equipment To Measure The Cell Transfer Performance Of ATM Connections) to transmit it to the ATM layer processor(100). The ATM layer processor(100) generates a header of an ATM cell with the VPI/VCI information and a payload of the ATM cell by using the test cell pattern. A frame processor(400) is divided by interfaces of a physical layer of a line to be measured in its quality. The ATM cell is applied to the line to be measured in its quality by the frame processor(400) and returns to a line quality measuring processor(300) through a local loop of the ATM exchange. The line quality measuring processor(300) compares information on the received cell and information on the initially applied test cell and extracts six quality indexes.
