Grandstream Networks GXW410X user manual Line #, AC Impedance, CPT Detection, External Number

TABLE 10: FXO LINE TEST TAB DEFINITIONS

	Note: The user can only test the 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 locally.
	For the AC Impedance Test we only need to select the line to be tested by clicking on
	the AC impedance box corresponding to that line, telephone numbers are optional.
	Remember that the AC impedance test is usually used to reduce the echo that might
	be present in the line.
	For the CPT test (call progress tones) we will test current disconnect as well. You will
	need 2 telephone numbers 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 tested line will use another line connected to the gateway to perform the test by
	calling into it, this is why you will have to enter the telephone number for a second
	line to help with the test.
	For CID detection you will need 2 telephone numbers 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 tested line will use another line connected to the
	gateway to perform the test by calling into it, this is why you will have to enter the
	telephone number for a second line to help with the test.
	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.
	Notes:
	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.
	If you log into the Web Interface while the test is running will not interrupt the
	process.
Line #	Enter the telephone (PSTN) number that corresponds to this line. Enter it as if you
	were going to dial it locally
AC Impedance	Select this box if you want to test for impedance on the line that is on the same row
	as the checked box. Remember that you can only check one item at the same time.
CPT Detection	Select this box if you want to test for call progress tones and current disconnect
	threshold on the line that is on the same row as the checked box. Remember that
	you can only check one item at the same time.
External Number	Enter an external telephone (PSTN) number to be used as an auxiliary number for
	the test. This is used only if we do not have at least 2 PSTN lines connected to the
	gateway. This is only used for CPT and current disconnect threshold testing. In order
	to use this function you will have to monitor the Syslog output. This is only reserved
	for very advanced users
External Call Timeout	This is the time the GXW will wait for the external telephone number to pick up during
	the test.
