Abstract
A telecommunication plant which can produce long and short distance carrier wave transmitting units, PCM digital transmitting units, optical cable communications equipment, transmission testers, and telegraph and computer terminals is presented. It can produce 9,000 transmitter terminals, 5000 voice channel systems, 2500 instruments, and 5 million various types of components annually. After expansion completion the production of PCM digital transmitting units will increase from 2000 to 4000 units, terminal transceiver units 5000 to 10000 units, and various components 20000 pieces.
