Abstract

For the test and maintenance of G. 703E1 transmit line, we designed a PCM line test device which is controlled by microprocessor 89S52, by using the functions of MT9075 chip such as line alarm, PCM line transmit, CAS and CCS. This device can monitor PCM line status, receive or send line voice, analyse line signal, by reading the commands of serial interface or the setting of DIP switch. This device is easy to operate and has a high ratio of quality and price.
