IT1000 Basic Rate ISDN Tester
ü
You can defeat the auto power off feature by unchecking the Auto Power Off box in Options > Configure
IT1000. This is useful if you are using the IT1000 on a mains power supply, especially if the unit is being used
remotely as it will prevent the unit from switching itself off.
You can also manually switch the unit off. To do this ensure the test selection is in the idle mode i.e.
none of the test selection LEDS are on, then press and hold the green mode/run button. The unit
will then power off.
3.3 IT-Explorer Mode
The IT1000 can also be used as a sophisticated protocol analyser to determine the cause of problems
on an ISDN line. Details of how to do this are in chapter 3 of this document.
