| Abstract: | The CS21354 microcontroller chip consists of E1 PCM-30/ISDN-PRI transceiver; it integrates the clock/data recovery and transmits the E1 pulse shape of chip line interface unit （LIU） and the E1 frame processor （Framer）. It may complete all test functions of the 2M digital population figures with the 2M bit error tester, including HDB3, AMI coding/decoding, clock extraction, each kind of frame structural signals, each kind of test patterns and each kind of alarm generation and detection, etc. In this paper, it presents the working principle about CS21354 in the 2M bit error tester, and discusses the tester＇s system software. |
