Digital Signal 3From Wikipedia, the free encyclopediaA Digital Signal 3 (DS3) is a digital signal level 3 T-carrier. It may also be referred to as a T3 line.
CablingDS3 interconnect cables must be made with true 75 ohm cable and connectors. Cables or connectors which are 50 ohm or which significantly deviate from 75 ohms will result in reflections which will lower the performance of the connection, possibly to the point of it not working. Bellcore standard GR-139-CORE defines type 734 and 735 cables for this application. Due to losses, there are differing distance limitations for each type of cable. 734 has a larger center conductor and insulator for lower losses for a given distance. The BNC connectors are also very important as are the crimping and cable stripping tools used to install them. Trompeter, Cannon, Amphenol, Kings, Canare are some of the true 75 ohm connectors known to work. RG-6 cable will also work, though it does not meet telephony technical standards. UsageThe level of transport or circuit is mostly used between telephony carriers, both wired and wireless. LinksSee also
