PSTN Auto Dectection Configuration
General Notes:
Users can only test parameters for only one of the PSTN lines at the same time. In all cases, please enter the telephone numbers as if the lines were to dial each other. For AC Impedance Test, telephone number and line is required to go offhook and onhook, no dialing indeed. AC impedance test is usually used to help to reduce line echo that might be present in the line. For call progress tone test, current disconnect is tested as well. 2 telephone numbers are required to perform the test. You can only perform the test on one line (row) at the same time and it will be the one that has the box checked for testing. This test line will use another line connected to the gateway to perform the test by calling into it. To perform the test, please select the line you want to test and the desired test to be performed. Enter the information for this line as well as a second line if necessary. Then click on the update button and then reboot. Log back in and now you should see the information for the line selected as well as the check box already marked already there. Go ahead and start the test now, please wait a few minutes until the test is done. Note: It is not required to enter a telephone number when testing for impedance, as the system does not place any actual calls for the test.
