IT1000 Basic Rate ISDN Tester
4.4.6
Set Time
Your IT1000 tester is equipped with a battery backed real time clock which has a resolution of ± 10
mS. This allows data written to the analyser log to be date and time stamped for future analysis.
You can use the Options > Set Date / Time option to set the correct time in the unit. By selecting
this option, a calendar appears with today's date and time as taken from your PC's clock. Click on
'Set Time' to transfer this date and time to your IT1000 unit.
Once set the battery will continue to operate the real time clock for up to 30 days even if there is no
other power source.

Configure Analyser
When your unit is shipped from the factory, it is set to capture all activity on the ISDN line at Layer
1 (Physical), 2 and 3 (LAPB & LAPD). If you are using the tester to home in on a particular
problem, it can be confusing to be presented with so much information.
This option, therefore, allows you to select which analysis is written to the analyser log. By using
this option together with selective use of the 'Clear Analyser Trace Before Each Test' option (on
the Options Menu), you can easily identify specific issues.
Notice from the above that you can also capture Raw ISDN Sync data on the D / B1 and B2
channels, this is useful for non-packet mode protocols such as V.120. By checking the
Asynchronous Port checkbox, you can also capture the data between your computer and the tester.
This mode is normally only used when the tester is used as a Terminal Adaptor.
