How to Turn the Test Set On
and Off
To turn on the test set, press Q. To turn off the test
set, hold down Q for 3 seconds. To set the time
period for the automatic shut-off function, see "Test
Set Timeout"on page 21.
How to Use the Monitor and
Talk Modes
The test set has two basic modes of operation: Talk
mode and Monitor mode. Talk mode is used for off-
hook operations (such as dialing verification, automatic
number identification, and audio quality verification).
Monitor mode is for audio monitoring of the Tip and
Ring pair while on-hook. In Monitor mode, the test set
has a high input impedance. This reduces the possibility
of disruptions to conversations or data while you
monitor the line
WWarning
When testing circuits that are close to a
battery source, clipping onto a line may
cause loud pops in the receiver. Holding the
receiver tightly against your ear may cause
acoustic shock. The test set is designed to
rest comfortably on the shoulder with some
space between the receiver and the ear. It
should be used in this position when
working close to a battery source.
Shorting the Tip and Ring leads together
while connected to a data line will disrupt
data on the line.
Monitor Mode
To put the test set in Monitor mode, press Q.
Note
If you press Q while in the test set’s menu,
your changes are not saved, and the display
goes back to the previous menu. (To save
changes, press
M before you press Q.)
In Monitor mode, the test set is always on-hook. The
test set draws no direct current from the line and it
transmits no signals to the line. In this mode, the test
set has a high ac input impedance. This reduces the
possibility of disruptions to conversations or data while
you monitor the line. You can use either the handset
receiver or the speaker to monitor a line.
To use the speaker to monitor the line, press
s. This
disables the handset receiver and sends all audio
signals to the speaker. Two volume levels are available:
normal (
%) and high ($). Press C D to toggle the
volume level. Press
s again to turn off the speaker
and monitor signals through the handset receiver.
In the Monitor mode, the test set is typically used for
one or more of the following procedures:
•
Verification that a line is idle when looking for a
line to borrow
•
Listening for noise on the line
•
Hunting for tracer tones
•
Measuring the dc voltage on the line
Caller ID
The display shows the Caller ID (CID) after the first ring
while in Monitor mode. CID shows these messages:
•
The incoming phone number and the name of the
caller, if available
•
Blocked ID (if CID is blocked by the
originating device)
•
Line error (CID data is incomplete)
•
Unknown ID (CID is not available)
Caller ID for Call Waiting
If you are on a call, and another call comes in, the caller
ID function for the second call operates similar to the
caller ID function for the original call.
