IT1000 Basic Rate ISDN Tester
TECHNICAL: 0870 90 10 750
The unit will continue to ring the specified number for 30 seconds or until the call is answered. On
answering the tester will play a pre-recorded voice message announcing itself to the person who
answered the call and the test will be considered successful.
If the tester is unable to dial the number either due to an incorrectly programmed circuit or a B
channel being unavailable, the test will fail. To cancel the voice answering (outgoing) test,
briefly
press the Mode/run button or in IT-Explorer mode, press the ESC key.
5.6 Voice Answering (incoming)
When this test is selected, the tester waits for an incoming voice call . When an incoming voice call
is received, the tester picks it up and plays a pre-recorded message to the caller. The test is then
considered successful. To cancel the voice answering (incoming) test,
briefly press the Mode/run
button or in IT-Explorer mode, press the ESC key.
5.7 Line Voltage
This test measures the voltage apparent on the line from the local exchange or the PABX if the line is
not directly connected to the exchange.
In stand alone mode, an indication of the voltage is given as a bar graph on the indicators. Note that
a voltage less than 10 Volts is indicated by only the Power indicator being on (i.e. no voltage
indicators) and any voltage over 70 Volts is indicated by all the indicators being on.
Z
The tester is only to be used to test voltages on an ISDN line in the manner described. ISDN lines carry a
maximum voltage of 90V. Under no circumstances must the tester be used as a general test instrument as this could
prove hazardous to the operator.
In IT-Explorer mode, the tester will display a more accurate reading of the line voltage on your
computer screen.
5.8 Email Logs
This test function is intended to be used when any of the preceding tests have failed and further
analysis is required by specialised support persons.
This function is selected on the indicators and the selection button on the tester is pressed and held
down for at least 3 seconds. The tester will then attempt to establish a PPP connection with an
Internet Service Provider then send an email to the pre-configured address.
