Introduction
Description
The TS1200 ADSL/POTS Test Set is an analog test telephone used by installers, repair technicians,
and other authorized personnel for the testing of copper wire, voice subscriber, and ADSL lines.
The TS1200 can test ADSL lines for throughput, noise margin, and other parameters. It can
monitor ADSL and POTS lines simultaneously and can test ADSL service in either a snapshot or a
continuous mode.
The same circuitry that allows the TS1200 to test POTS services without downing ADSL also
prevents the test set from disrupting other types of digital data services (xDSL, ISDN) to which
the test set may have been unintentionally connected.

Connecting the TS1200 to an ADSL Line
Figure 2-2 shows a typical ADSL over POTS connection from a Central Office (CO) to the
customer’s premises. A TS1200 in Monitor mode may be connected to the Tip and Ring pair, at
any point in the connection, without interfering with the services on the line while ADSL tests
are not running.
The TS1200 may be used in Talk mode at locations on the line carrying only voice or voice and
data. Attempting to put the TS1200 in Talk mode on the portion of the line carrying voice and
data will result in a data lockout. The test set will not go off hook until the data lockout is
overridden (See POTS Mode Features).
The ADSL test functions in the TS1200 may be used at locations on the line carrying only data or
voice and data. However, the TS1200 ADSL tests will not run properly if the ATU-R is active.
Running the ADSL tests while the ATU-R is active may cause it to loose synchronization.
Notes
Running the ADSL tests in the middle of a line may result in low data rates or
no showtime, depending upon the length and condition of the line
between the TS1200 and the customer’s premises. Open the line between
the TS1200 and the customer’s premises to improve the ADSL connection.
Data rates obtained in the middle of a line will not be the same as data rates
obtained at the customer’s premises.
Achieving showtime in the middle of a line does not guarantee that
showtime can be achieved at the customer’s premises.
Speaker A speaker icon appears when the Speaker is on.
On/Off Hook The test set displays a telephone in the upper left-hand corner of the LCD screen that
indicates when the test set is on or off hook.
Volume Normal volume is represented by two parallel lines on the LCD screen. High volume is
represented by three parallel lines.
Mute Mute is represented by an M in the upper left-hand corner of the LCD screen.
Tone/Pulse Tone is represented by a musical note at the top of the LCD screen. Pulse is
represented by a square wave at the top of the LCD screen.

Auto and Manual
ADSL Test Results
The following obtained upstream and downstream results are shown on both
the Showtime Display screens for Manual Test and Auto Test:
MaxB/R (Maximum Bit Rate): Displays the maximum attainable bit rate.
Results are presented in kbits/s. The measured values for upstream and
downstream should be greater than or equal to the minimum bit rate set in
the ATU-C.
B/Rate (Bit Rate): Displays the achieved Fast bit rate data path. Results are
presented in kbits/s. The measured values for upstream and downstream
should be greater than or equal to the minimum bit rate set in the ATU-C. The
result may be 0 if the Interleaved data path has been enabled by the ATU-C
Capac: Displays the capacity of the line as a ratio of achieved bit rate (B/Rate
or IntB/R) over the maximum attainable bit rate. Results are presented as a
percentage (%). A lower capacity reading generally implies greater noise
immunity.
IntB/R (Interleaved Bit Rate): Displays the achieved interleaved bit rate. Results
are presented in kbits/s. The measured values for upstream and downstream
should be greater than the minimum bit rate set in the ATU-C. The result may
be 0 if the Fast data path is turned on in the ATU-C.
NseMar (Noise Margin): Displays the realized noise margin. This is the amount
of increased noise relative to the measured noise power that the system
would be able to tolerate to maintain a bit error rate less than 10-7. Results are
presented in dB. The industry standard is for a minimum value of 6 dB.

Out Pwr (Output Power): Displays the aggregate power which is a measure of
total output power. Results are presented in dBm. Typically the power output
is the minimum required to achieve the noise margin that the ATU-C had
been configured for.
Atten (Attenuation): Displays the total attenuation. The attenuation is the
measured difference in dB between the power transmitted at the near end
and received at the far end. Any value reported by the TS1200 that is greater
than 31 dB should be interpreted as 31 dB or higher.
Alarm Status The Alarm Display provides information on loss of signal (LOS), loss of frame
(LOF), loss of power (LOP), and loss of margin (LOM). Information is provided

Using POTS Mode
Note
Pressing the Home key at any screen returns you to the Home screen.
POTS mode can be entered by selecting 1on the Home Screen (the first screen displayed upon
powering up the unit) or by pressing the POTS/ADSL key.
POTS Mode Features
Monitor Mode
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, which allows monitoring of the line without disrupting
conversations or data signaling if present. The test set draws no direct current from the line and
it transmits no signals to the line.
In the Monitor mode, the test set is typically used to perform 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
• Performing a test for the presence of high frequency data on the line
Saving Test Results The user can save the test results or print out the results. Save Results can be
selected from either Auto or Manual Test.
To save or print the results:
1From the Showtime Test Results screen, press F3 - Exit.
2Press F1 - Yes.
3Press F2 - Edit.
4Move cursor to either Name or Number using Up/Down arrow keys.
5Make entry and press F1 - Save. The results are automatically saved.
See “Downloading Stored Results to a PC” for instructions on sending stored
results to a PC.

2-9
Using POTS Mode
WCaution
When testing circuits that are close to a battery source, the pops in the
handset receiver that result from clipping onto a line may be quite
loud. Although there is protection against acoustic shock built into the
test set, if the receiver is held tightly against the ear, acoustical shock
may occur. The TS1200 Test Set is designed to rest comfortably on the
shoulder with the receiver away from the ear. It should be used in this
position when working close to a battery source.
Talk Mode
When switched to Talk mode, the TS1200 goes off hook and draws dial tone. When off hook,
the test set operates like a standard telephone; it is typically used to verify the proper operation
of a voice telephone line or to establish temporary communications on a “borrowed pair”.
Data Lockout
During the transition between Monitor and Talk modes, a sub-mode may be entered if data is
present on the line. This sub-mode is referred to as Data Lockout mode. In the Data Lockout
mode, the unit is kept on hook, or locked out, despite having been switched to Talk mode. Data
Lockout mode is provided to help prevent accidental corruption of a data transmission while
working on the lines. The lockout may be overridden and the test set taken off hook, despite
the presence of data, if the user desires to.
Note
When the TS1200 ADSL modem is active, data lockout will not occur.
Data Lockout Override
The following are scenarios where the operator may wish to override a data lockout:
• When there is false data detection due to RF pickup on a line that is near an AM radio
broadcast antenna. The RF induced in the line may appear to be data.
• When accessing POTS on a subscriber line that carries both ADSL and POTS.
Telephone lines near AM radio broadcast facilities, pick up the RF signals from the broadcast
antennas. Normally this isn’t a problem for the TS1200. If the line is well balanced, the TS1200
will not see the RF signal because it is a common mode (longitudinal) signal. But if the line isn’t
well balanced, a portion of the RF signal will be converted to a differential (metallic) signal. If
the signal amplitude is high enough, it may be detected as high-speed data by the TS1200. If you
know for sure you are on such a line, use the unit’s override capability to go off hook.
Note
Lockout override can be activated only when the test set is locked out.

2-10
TS1200 Test Set
Users Guide
To activate data lockout override, press F1 - Ovride from the Data Lockout screen. If DC voltage is
present on the line, the test set stops alarming and goes off hook, allowing the user to perform
normal Talk mode functions.
To go back on hook, select F2 - Hangup. This puts the test set back in Monitor mode. The override
must be manually reactivated each time the user wants to take a locked-out test set off hook.
WCaution
Shorting the Tip and Ring leads together while connected to a data
line causes disruption to the data.
POTS Mode Operations
Making a call on the
POTS portion of the line
You can make calls on lines that have ADSL as well as those that do not. You
can also make calls while simultaneously testing the ADSL portion of a line.
Use the POTS/ADSL key to toggle between POTS and ADSL.
Originating a Call To originate a call:
1Clip the test set to Tip and Ring of a powered subscriber loop.
2Monitor (listen to) the line to verify it is idle.

4If idle, go to the POTS screen.
5Press F2 - Talk. The test set automatically tests for high-speed data and
talk battery on the line.
6If data is detected, the test set will not go off hook (will lockout) and will
beep indicating the presence of data. Try another line, or if you are sure
the data detection is false, you can override the data lockout (see Data
Lockout Override).
7If no data is detected, the test set will go off hook.
8The numeric keypad, LNR (F3), or SPD Dial may be used to dial a number
for originating a call.
