Line Cord

See Figure 4.
The TS30 comes with a line cord for connecting the test
set to telephone lines. This line cord consists of one red
and one black insulated conductor, each approximately
1.5 meters long. Each clip is covered with a neoprene
boot to prevent the clips from causing electrical shorts.

When connecting to metallic network wires,
handle alligator clips by insulated boots.

Line Monitoring

Move the TALK/MONITOR switch to MONITOR and
connect the red and black test leads to the telephone
line wire pair under test. If there is any audio on the
line under test, it can now be heard in the unit's
receiver. Because the TS30 presents a high impedance
to the line when in Monitor mode, it will not disturb
existing signals on the line under test. Monitor mode is
typically used by service personnel to verify that there is
no call in progress on the wire pair before going off-
hook.

Warning

Dialing

If tone dialing is selected, the tones associated
with each digit will be generated as its
respective key is pressed. If pulse signaling has
been selected, the desired number may be
entered at any rate on the keypad. The digits
will automatically be pulsed out at the correct
rate.
Move the TALK/MONITOR switch to the MONITOR
position and connect the red and black test leads to the
wire pair under test. Move the TONE/PULSE switch to
select the desired dialing mode. Move the TALK/
MONITOR switch to TALK, and verify that dial tone is
received. Enter the number to be called on the keypad.
To end the call, either during or after dialing, move the
bfl04.eps
TALK/MONITOR switch to the MONITOR position.

Flash

Some telephone services require a timed hook flash
(approximately ½ second on-hook/off-hook loop
interruption) to activate features. The FLASH key
provides this timed hook flash signal.

Mixed Mode Dialing

On some telephone lines, calls can only be set up by
pulse dialing. Once the call is established in Pulse mode,
then the TONE/PULSE switch can be moved to the
TONE position. Tones can now be sent over the
telephone lines by pressing dialing keys. This is useful
when there is a need to send dialing tones as data to
activate some function in a device connected to the
other end of the telephone line. For example, dialing
tones can be used to command an answering machine
to play back recorded messages.
