Calling Operations
The TLS-4A provides dial tone to a line when the telephone handset is lifted.
When a rotary dialed or tone digit is detected, dial tone stops. If a number is
misdialed, reorder tone (or another programmable tone) is sent to the caller or
the caller is connected to the audio port (see command 31 on page 34).
Accepts tone and rotary input
·
Ringing voltage source with short circuit protection
·
AC powered (battery not required)
·
Non-volatile memory (battery not required)
·
Generates precise call progress tones
·
Ground reference jack
·
-48 V ground referenced line voltage
·
Audio port
·
When a valid number has been dialed, ringback tone is sent to the caller and
the called line rings. When the called line answers, ringback tone stops and a
connection is established between the parties. When either party goes
on-hook, the off-hook line receives about 2 seconds (default) of silence,
followed by dial tone, or Cutoff on Disconnect. See command 38, Forced
Disconnect, on page 38 for more information.
Physical Description
The TLS-4A is a portable unit weighing just over 4 pounds. A detachable
power cord is supplied with the TLS-4A. As shown in Figure 1, the front panel
provides: four modular RJ-11 jacks for connection of the equipment to be
demonstrated or tested, a multifunction switch (see Table 1), and the
indicators listed in Table 2. A 5-pin DIN jack on the back panel enables
sending or receiving audio to/from any line. The audio is turned on or off by a
software-driven relay. A fused, modular AC power jack and an optional
chassis ground reference point are also located on the back of the unit.
For key telephone and PBX line testing, a modular/alligator clip cable can
(Figure 4) enable connection of lines from a
terminal block to the TLS-4A.

Telephone Line Simulator 4A
Chapter 2: Feature Applications
The TLS-4A offers an array of programmable features to suit a variety of
applications.
Two Numbers Per Line
Each of the four lines can be assigned two telephone numbers, each number a
maximum of 16 digits long.
This feature may be used to program one number with a standard ring
cadence and the other with a nonstandard ring cadence. Another use might be
to assign all four lines the same second number in order to setup a hunt group
or ring all telephones with one call.
Ring cadences on the second phone number can be varied, confirmation and
error tones disabled, and audio port access blocked from certain lines. Hot line
(“ringdown”) numbers and hunt groups can be setup. These and other
programmable features are described in Chapter 6. The unit is programmed
by connecting a tone (DTMF) telephone to the unit and entering digit codes.
Audio Port
The audio port can be configured for immediate or dial access or as a monitor,
may allow single or multiple lines to be connected simultaneously, and can
vary the method of turning off the recorded message.
Distinctive Ringing
The ring cycle timing for the first number on each line is always the standard 2
seconds on, 4 seconds off. The ring cycle timing for the second number on each
line is programmable. (See Programming.) This gives the ability for each line
to have two different ring cycles by simply dialing the two different numbers
associated with that line.
Group Ringing
It is possible to have a group of phones that can be rung simultaneously, yet
still be able to ring them individually. By programming different first numbers
for each line, but the same second number for each line, and having the hunt
mode set to “ring all”, dialing the first numbers will ring an individual phone
(with standard ringing), and dialing the second number will ring all the
phones simultaneously (with distinctive ringing).
Page 4
Reference Manual Chapter 2: Feature Applications
Invalid Number
You can program how the TLS-4A will respond to an invalid number. It can
respond with busy tone, reorder tone, ringback tone, silence, or it can connect
the calling line to the audio port. Regardless of the response you select, there
will be a delay before the response is activated.
If an invalid number beginning with any number other than “1” is dialed,
the TLS-4A will respond after 7 digits have been entered or after 8 seconds
have passed.
-or-
If an invalid number beginning with “1” is dialed, the TLS-4A will simulate
the telephone network’s delay by waiting until 11 digits have been entered or
8 seconds have passed since the last digit was entered.
If you program the TLS-4A to connect invalid numbers to the audio port, calls
arriving when the audio port is already in use will get busy tone.
Uses for Off-Hook Modes
A detailed explanation of command 32, Off-Hook Modes, is provided in
Chapter 6.
Standard Mode
This provides normal dialing features.
Hot Line Mode
Hot line mode is normally used to ring one phone automatically the moment
you pick up another. To use this feature, program the off-hook mode for the
line from which you will make the call as “hot line” (see Chapter 6 for details).
Program the “revert/hotline” number to the first or second number of the line
you wish to ring. When you go off-hook on the originating line, ringback will
be heard, and the destination line will ring.
Silent Mode
This mode can be used to provide silence when you go off-hook. To use this
feature, program the off-hook mode for “silence”. Any or all of the lines can be
used in this way.
40-400-00033, Rev. C
Page 5
Telephone Line Simulator 4A
Uses for Hunt Mode
Hunt Mode, command 35, can be used to Simulate Trunk Groups/Telethons.
Please see Chapter 6 for a detailed explanation of this command.
Ring First/Ring Next/Ring All
When Hunt mode is set to “ring first available”, “ring all”, or “ring next” with
multiple lines set to the same phone number, it simulates a group of lines with
a single pilot number (like the trunks into a PBX system). “Ring first available”
will always ring the lowest non-busy line. This will cause the lowest line to
receive the most calls. “Ring next” will ring the next non-busy line in sequence
above the last one to have rung. “Ring all” will ring all the lines until one goes
off-hook.

Tape Recorders
Please use tape recorders without automatic or dynamic level control because
automatic level control can amplify background noise, ruining the silent
period at the end of the message.
Notes:
(1) Always use a new tape or one that has been erased because the
TLS-4A looks for three seconds of silence followed by a sound for an
“end-of-message” indication. See “End of Message Tape Sequence” at
thend of this section.
(2) Be sure the tape used is the correct bias type for the recorder.
