Link CX-24 User’s ManualVersion 1.0 Page 15 February 2004Figure 2.2 – Typical EMS/NMS Ethernet Connections2.5 Planning DS-3 LinksThe Link CX-24 DS-3 version uses paired 75 Ohm cables with male TNC connectors for the transmit andreceive data from external DS-3 equipment. YDI sells 25 m (82 ft.), 50 m (14 ft.), and 100 m (328 ft.) DS-3cables with the correct connectors for these links, as described in Section 1.7.6.2.6 Power PlanningYDI sells 25 m (82 ft.), 50 m (14 ft.), and 100 m (328 ft.) power cables with the correct connectors for LinkCX-24 power, as described in Section 1.7.6.2.7 Transmit Power PlanningThe Link CX-24 normally uses a manually-set output power level. When Automatic Transmit PowerControl (ATPC) is enabled, the far-end Link CX-24 terminal provides feedback to the near-end Link CX-24 to set the transmit power to the lowest level required for clear data transmission.Transmit power can be attenuated by 40 dB for initial configuration and interference isolation. Also, amaximum transmit power level can be set (whether or not ATPC is enabled) between –30 dBm and0 dBm to prevent interference with other RF receivers.
