Introduction
The 46054 GTS-D Butt-in Test Set is an advanced, convenient, and easy-to-use telephone line
troubleshooting device. Equipped with a number of LEDs and alarms, the 46054 lets the user
know the operating mode and provides alerts for hazardous situations.
LEDs: Polarity
Low Battery
Talk/Monitor
Tones: Low Pitch
Middle Pitch
High Pitch
The LEDs and tones indicate various conditions and functions. They are shown throughout the
manual in
italic type.
The 46054 produces two types of alarms to alert the user to potentially hazardous situations.
•
Excessive DC voltage is indicated by three low-pitched tones in a row.
• AC line voltage is indicated by continuous ringing.
If you hear either of these alarms, which are repeated in
bold italic type
in this manual,
remove the test set from the line carefully and immediately.

Operation
The test set must have a charged battery installed in order to operate.
1. Connect the red wire to the ring (negative) side of the circuit.
2. Connect the black wire to the tip (positive) side of the circuit.
3. Use the Talk, Monitor and Mute features as described in this section.
Automatic Ground Start
Some lines, especially PABX, require a momentary ground to draw a dial tone.
Connect the test set’s red and black wires to the telephone circuit as usual, and connect the
green wire to ground. Press the TALK button momentarily to check for dial tone.
The ground start is automatic, and the green wire can remain connected without affecting the
call.
TALK
Press once to go off-hook (connect). Press again or press MONITOR to go on-hook
(disconnect).
▼
Off-Hook Mode
LED: Flashing red
Tone: Middle Pitch–Middle Pitch
▼
On-Hook Mode
LED: None
Tone: Middle Pitch
Automatic Line Checks
After the TALK button is pressed, the 46054 automatically checks the line for the presence of
digital signals. If it detects digital signals, the speaker will produce a distinctive alarm
(Middle
Pitch–Low Pitch, Middle Pitch–Low Pitch, Middle Pitch–Low Pitch)
to indicate that the test set
is connected to a digital line. To prevent disturbance to the digital information being transmit-
ted, the test set will not go off-hook while connected to this type of line.
After determining that the line is free of digital information, the test set checks for excessive
voltages. If the test set signals either the excessive DC voltage alarm
(low pitch, low pitch,
low pitch)
or the AC line voltage alarm
(constant ringing),
remove the test set from the line
carefully and immediately!

Operation (cont’d)
MONITOR
Press once to monitor the line without disturbing data, signal, or voice transmissions on the
line. Press repeatedly to alternate between Monitor mode and off.
To conserve battery life, the test set will shut off after 20 minutes of monitoring or 90 seconds
after removal from the line.
▼
Monitor Mode
LED: Flashing green
Tone: Middle Pitch
MUTE
Press and release to stop transmitting over the line, to filter outside noise from the line, or to
eliminate sidetones. Press again to talk. Mute works only when the test set is in Talk mode.
▼
Mute Mode
LED: Flashing red
Tone: Middle Pitch (Mute ON)
Tone: Low Pitch (Mute OFF)

Dialing Features
PULSE
Pulse Dialing
Press PULSE, then press TALK.
The dialing mode will automatically return to tone-type dialing when the test set is removed
from the line or when the test set is switched off.
To mix pulse and tone dialing, select PULSE and dial the pulse digits. Then press to select
TONE and dial the tone digits (the will not be dialed).
Note: If the dialing string is started in Tone mode, it is not possible to add Pulse digits.
The Last Number Redial feature (explained later in this section) will dial this number as a
mixture of pulse and tone digits.
To dial this number from memory (explained later in this section):
• setting the dialing mode to Pulse before pressing MEM will dial the number as a mixture of
pulse and tone digits
• setting the dialing mode to Tone before pressing MEM will dial the number as tone digits
only
LNR/PAUSE
Last Number Redial / Pause
Immediately after going off-hook, press LNR (last number redial) to redial the dialing string
from the previous call.
When dialing, press PAUSE to insert a four-second pause in the dialing string.
STO
MEM
Store and Memory
The 46054 can store up to 10 telephone numbers, one under each of the digits (0–9).
To store a telephone number:
1. While connected to a line and in the Talk mode, press STO.
2. Enter the telephone number.
3. Press MEM.
4. Press one of the digits (0–9).
In addition to digits, the memory will also store ,, (flash) and (pause).
To recall and dial a stored telephone number:
1. While connected to a line and in the Talk mode, press MEM.
2. Press the appropriate digit (0–9).

Other Features
FLASH
Flash
Press FLASH to generate a timed line break.
SPKR
Speaker
The speaker allows two different modes: one-way hands-free operation and two-way hands-
free operation.
• When in the Talk mode, press SPKR to communicate in the two-way hands-free mode.
• When in the Talk mode, press MUTE, then press SPKR. This puts the test set in the one-way
(receive-only) hands-free mode.
• When the test set is off, press and release SPKR to select Monitor mode with loudspeaker.
Press again to select Monitor mode without loudspeaker.
VOL
Volume Control
To control the speaker volume, press VOL. The speaker is set to automatically start out at the
low setting. Press VOL to toggle between high and low volume.
Note: When using the high volume setting, the dial tone may fade. This does not indicate a
fault or a problem, and you may still dial out.
POL
Polarity
To determine the polarity, press POL. The LED will indicate polarity as follows:
▼
Red wire connected to ring (negative)
LED: Steady green
▼
Red wire connected to tip (positive)
LED: Steady red
Pressing POL while ringing will cause the LED to alternate between green and red.
