Nonstandard Ring Cadence Test
To test equipment that looks for particular ring cadences, proceed as follows:
Note:
Line 1 is used to enter programming mode, but any line can be used for
test. Lines 1 and 2 are used as examples in the steps below.
·
Go off-hook on Line 1 and press and hold the MAN/RING switch position
until the Line 1 LED blinks and three beeps are heard.
-or-
·
Go off-hook on Line 1 and dial **99##, Line 1 LED blinks and 3 beeps are
heard.
·
Select Line 2 with the command
*
02#
, then program the desired ring
cadence as described in Chapter 6, command 23. (The default cadence is 1
second on, 1 off, 1 on, and 3 off.)
·
Change the second phone number for Line 2 with the command
*12#NNN...N#
. (The default for the second phone number is 202.)
·
Hang up Line 1. Programming complete.
·
Go off-hook on Line 1 and dial the second phone number for Line 2.
·
Verify that Line 2 rings with the programmed ring cadence and the device
under test recognizes rings.
Dial Pad Check
The following verifies that all seven frequencies generated by the tone pad are
operating and that the telephone can receive audio signals.
·
Plug a known working phone into Line 1.
·
Go off-hook on Line 1 and press and hold the MAN/RING switch position
until the Line 1 light blinks.
·
Enter the following command:
*
12#1234567890#
. (This programs the
second phone number for Line 2.)
·
Make sure the number does not conflict with other telephone numbers
programmed into the unit.
·
Listen for a three-beep confirmation and hang up.
·
Connect the telephone under test into Line 1.
·
Go off-hook on the phone to be tested, wait for dial tone. Enter:
1234567890
.
·
Verify that dial tone stops, ring back tone is heard, and Line 1 rings after
the last digit is dialed. Go on-hook.
