The
automatic mode, besides being used to test phone equipment, is also perfect for use as a front entry
intercom for home or office use. Place a phone near you and one near your entry. Be sure to post a
note near the entry phone that instructs your visitors to “lift the receiver for assistance.”
[d] Dumb Mode
The
dumb mode provides a silent talk path and allows a manual ring. You will not hear any call progress
tones; however you can converse normally.
T
EST
line ringing is controlled by using the R
ING
switch or the M
AIN
phone's “
L
” key. The ring signal will
follow the key presses. Unlike the other modes, they do not continue to ring when the keys are released.
Whenever the T
EST
line is taken off hook the two lines will be automatically connected together.
The
dumb mode is perfect for testing the basic operation of equipment. Because you can control the
duty cycle (cadence) of the ring signal, non-standard equipment can be tested for ring operation.
[b] Beep Tone Mode
The
beep tone mode is specially designed for cycle testing answering machines and other types of
telephone equipment. This mode does not start until the Ring button or DTMF “*” key is pressed.
It is not necessary to have the M
AIN
line’s phone off-hook during the
beep mode. Whenever the T
EST
line is answered a series of repeating test tones are sent to the telephone equipment being tested.
During the beep mode the T
EST
line automatically rings after a short delay (time delay is adjustable at
rear of unit). If the line is answered, staggered beep tones are played. These tones have been designed
to keep a voice controlled answering machine from hanging up. The ring-up cycle repeats (after an
adjustable delay) until it is canceled by pressing the M
ODE
switch).
For example, if the delay control (on the rear panel) is set for thirty seconds, the device being tested will
be rung-up thirty seconds after the last answer/disconnect cycle. The test tones will be played as long
as the T
EST
line is off-hook. If the T
EST
line goes on-hook, the delay cycle starts up again.
[c] Cycle Mode
The
cycle mode provides most of the features of the beep mode except that the beep tones are not
played and a phone must be plugged into the M
AIN
line. To start the cycle you must pick up the phone
M
AIN
line telephone. If either line is off hook when the other is picked up, the two lines will be
automatically connected together.
When the T
EST
line answers, your conversation may begin. If it hangs up and the M
AIN
phone remains
off-hook, the T
EST
line is automatically rung up after the delay time. This cycle repeats until the M
AIN
phone is hung up.
Beep and Cycle Mode Operation
To use the
Beep or Cycle modes with the delay feature, connect an answering machine or telephone to
the T
EST
line. If you are using the cycle mode be sure to also install a phone in the M
AIN
line jack. Start
line ringing by lifting the M
AIN
line’s phone off-hook (cycle mode) or pressing the R
ING
switch (beep
mode).
