Basic Calling Operation
The TLS-5 provides dial tone (or Silence or Ringdown, see command 32) to a
line when the telephone handset is lifted. When a rotary dialed or DTMF digit
is detected, dial tone stops. If a number is misdialed, Reorder tone (or another
programmable tone, see command 39) is sent to the caller or the caller is
connected to the audio port (see command 31).
When a valid number has been dialed, ring back tone is sent to the caller and
the called line rings (see command 11, 12 for numbers, 07 for Ring Type, and
23 for ring cadence). When the called line answers, ring back tone stops and a
connection is established between the parties. When either party goes on-hook,
the off-hook line receives 2 seconds (default, see command 9) of silence,
followed by dial tone, or Cutoff on Disconnect. (See command 38, Forced
Disconnect). Calling Party Control supports the operation that if the first party
goes back off-hook, the connection to the other party will be re-established. If
the Device Disconnect Timer (command 9) expires, the party will receive dial
tone.
Physical Description
The TLS-5 is a portable unit weighing just over 4 pounds. A detachable power
cord is supplied with the TLS-5A and TLS-5C; it is not supplied with the
TLS-5B and TLS-5D. 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 multi function switch (see Table 1), and the LED 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 a 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 5) enable the connection of lines from a
terminal block to the TLS-5.
