摘要：
THIS ARTICLE INTRODUCES ERICSSON'S DIGITAL LINE SYSTEM FOR 140 MBIT/S, CORRESPONDING TO 1920 TELEPHONE CHANNELS, ON NORMAL AND SMALL-CORE COAXIAL CABLE. THE SYSTEM MEETS ALL RELEVANT CCITT AND CEPT RECOMMENDATIONS. IT IS PARTICULARLY SUITABLE FOR SPARE TUBE PAIRS IN EXISTING COAXIAL CABLES. THE CHOSEN REPEATER SPACING IS THEREFORE THE SAME AS FOR THE ANALOG12 MHZ LINE SYSTEM IN ORDER TO SIMPLIFY CONVERSION FROM ANALOG TO DIGITAL TRANSMISSION AS WELL AS TO PERMIT MIXED OPERATION OF ANALOG AND DIGITAL SYSTEMS ON THE SAME CABLE. THE EQUIPMENT IS CHARACTERIZED BY GOOD TRANSMISSION PERFORMANCE AND EASY INSTALLATION, CHARACTERISTICS WHICH HAVE BEEN VERIFIED IN FIELD TRIALS.
