4 RUNNING THE IT- EXPLORER SOFTWARE
4.1 Concepts
If it is necessary to investigate problems on an ISDN line beyond the basic tests available in stand
alone mode or if it is required to re-program the test parameters, such as the number to be called in a
voice test, it is necessary to use the supplied IT-Explorer software.
The software is designed to run on any PC which runs the Windows 98
®
or later operating system, it
will also run satisfactorily on a Windows NT
®
platform.
By means of the IT-Explorer software it is also possible to access a remote IT1000 in the field to
determine the status of an ISDN circuit which may be hundreds of miles away, thereby saving
unnecessary maintenance visits. To enable IT-Explorer to make a physical link to the remote unit,
you must have a PC or Laptop with an ISDN connection capable of making an outbound V.120
connection. (note: this can be another IT1000 with option 2 fitted).
4.2 Installing the software
The IT-Explorer software is supplied on a CD-ROM with the tester.
To install it insert the disc into your CD-ROM drive and wait for the installation instructions to
appear on your screen.
The application software is very compact and takes less than 4Mb of space on your computer.
4.3 Running IT-Explorer
To use IT-Explorer to connect to a local IT1000 tester, firstly attach one end of the supplied cable to
the port on the tester labelled DTE and the other end to a free serial port of your PC or laptop
computer, then switch on the tested as described in Chapter 2.

Be careful not to confuse the two ports on your tester. Connecting an ISDN line to the DTE port can cause physical
damage to your unit and should be avoided.
You can also use the IT-Explorer software to connect to a remote tester. This is very useful if you
send a tester to a remote site and need to make it run tests from your PC and get instant confirmation
of the results.
The easiest way to connect to a remote tester is by using another IT1000 unit as they are
preconfigured to operate in this way, however, any ISDN Terminal Adaptor capable of Multiframe
V.120 can be used. If you use a third part TA, ensure you correctly set the initialisation string (see
4.4.2 Initialisation String)
