1 FOR INTERCONNECT AND CROSS-CONNECT APPLICATIONS HIGH SPEED DS-3 & DS-4 CABLES

2 Belden Your Widest Selection for Meeting DS-3 and DS-4 Network Requirements BELDEN, THE CABLE TECHNOLOGY LEADER IN HIGH-SPEED DATA TRANSMISSION, NOW OFFERS THE LARGEST SELECTION OF COAX CABLE SPECIFICALLY DESIGNED FOR DIGITAL SIGNAL (DS) INTERCONNECT AND CROSS-CONNECT APPLICATIONS IN THE CENTRAL OFFICE. DS-3 and DS-4 Transmission Formats Digital Signal Level 3 (DS-3) and DS-4 are the transmission formats used in telephone equipment to carry traffic in Central Office facilities. DS-3 is a signal capable of 672 multipleed voice channels, or 28 T-1s. DS-3 systems operate at a transmission rate of Mbps and a frequency of MHz. DS-4 has a channel capacity of 4,032 voice channels, a transmission rate of Mbps, and a frequency of MHz. DS-1 (1.544 Mbps) and DS-1C (3.125 Mbps) are other standards from the North American digital hierarchy. DS-3 and DS-4 Cables Bellcore GR-139-CORE (Generic Requirements for Central Office Coaial Cable) contains and defines the requirements CENTRAL OFFICE for coa cable utilized in DS-3 and DS-4 systems. 734A*, 734D* and 735A* are industry references for coa made for Central Office applications in general, and Digital Signal Cross-connect (DSX) applications in particular. All Belden s DS-3 and DS-4 Coa Cables conform to the requirements of Bellcore GR-139-CORE. Cross-connect or Interconnect Applications Cross-connect applications are those within a DSX. A DSX frame is an array of equipment operating at a particular digital transmission rate. Interconnect cables are those carrying signals between a DSX and a multipleer or other transmission equipment. Digital Multipleers (MUX) combine and de-combine individual voice channels for transmission or distribution. DS-3 and DS-4 signals are also carried within and between patch panels, transmitters, receivers and telephone switches.
