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
Testing for dc voltage on the line by using the Vdc/
mA TEST key
Caller ID
The display shows the Caller ID (CID) after the first ring
while in Monitor mode. The CID messages are:
The incoming phone number
Blocked ID (if CID is blocked by the originating
device)
Line error (CID data is incomplete)
Unknown ID (CID is not available)
Lines carrying high speed data and voice
require a splitter (filter) for Caller ID.
Operating the Test Set in Talk Mode
Right after moving the Talk/Monitor switch to T, the
test set performs a brief test for high-speed data and it
looks for talk battery on the line. If high-speed data is
detected, the test set generates an audio alarm and
remains on-hook. If high-speed data is not detected
and talk battery is present, the test set goes off-hook.
When off-hook, the test set operates like a standard
telephone and is typically used to verify the proper
operation of a voice telephone line or to establish
temporary communications on a "borrowed pair".
Originating a Call
Set the Talk/Monitor switch to M.
1
Clip the test set to Tip and Ring of a subscriber
2
loop.
Monitor (listen to) the line to verify that it is idle.
3
If not idle, disconnect the test set from the line.
4
Note
If the line is idle, set the Talk/Monitor switch to T.
5
The test set automatically tests for high-speed data
and talk battery on the line.
If data is detected, the test set will not go off-hook
6
and LOCKOUT is shown on the display. Try another
line.
If there is no data and talk battery is present, the
7
test set goes off-hook and draws dial tone.
The test set will not go off-hook if the line
voltage exceeds 140 V dc.
Dial the desired number.
8
If you mis-dial the number, switch the Talk/
Monitor switch to M and then back to T and
enter the number again.
Disconnecting a Call
To disconnect a call, set the Talk/Monitor switch to M or
remove the test leads from the line.
Answering a Call
If a ringing signal is received, set the Talk/Monitor
1
switch to T. The test set automatically tests for
high-speed data on the line.
If there is no data and talk battery is present, the
2
test set goes off-hook.
The TS52PRO will not go off-hook if the line
voltage exceeds 140 V dc.
If data is detected, the test set will not go off-hook
3
and LOCKOUT is shown on the display.
To go off-hook with data present, press the
4
OVERRIDE key (see "Data Lockout Override
Operation" on page 13).
