Chapter 4 Coax Cable Field Calibration and Testing Figure 4-1: IBM COAX Cable Type Screen For COAX Field Calibration, please follow the instruction below: 1. Connect the COAX adapters to the Display Handset (DH) and Remote Handset (RH). 2. Insert the short COAX calibration cable into both the DH and RH adapters. 3. From the DH Ready Screen, press F3 or highlight Field Calibration icon and press ENTER. 4. Select START by pressing F1 to begin the calibration process. Once the calibration process completion screen appears, select ESCAPE to return to the main screen. 5. When the calibration process is completed, the LANTEK is ready for testing.

Chapter 4 COAX Cable Field Calibration and Testing TROUBLESHOOTING COAX CABLING Always use high quality connectors and tools to properly terminate COAX network. In case of a cable fail, look for the following cases: ‣ FAULTY TERMINATION - Make sure you have properly separated the center conductor from the shield. ‣ CABLE SHORT - This could occur from improper termination both at near-end and far-end. In case of a SHORT, look for the Resistance value on the tester. A zero (0) – Ohm resistance value will suggest the fault is at the near-end of the cable, while a ~ 20 – Ohm value will suggest the fault is at the far-end. ‣ CABLE OPEN - A common case. To diagnose this situation, look at the cable length measurement. A zero (0) cable length will suggest a fault at the nearend. ‣ USE of TDR to Diagnose Problem - The LANTEK build-in copper TDR is a good tool to identify the location of the fault and distance of the fault. Refer to the TDR operation in this manual for more details. 4-4
