calls. Any additional callers will receive a busy signal. This feature is
supported only when calling using the four lines, calls to Test Tones or the
Audio port do not support Call Waiting tones. The TLS-5 supports the ability
to Cancel Call Waiting, just like the telephone network, by dialing *70 prior to
dialing a telephone number. Call Waiting may also be turned on or off (see
command 40) for each individual line. Additional Call Waiting functionality is
available on the TLS-5Cand TLS-5D models.
Note:
Cancel Call Waiting does NOT work in conjunction with any other
prefix functions, such as the special Caller ID codes or Visual Message
Waiting. Call Forwarding is incompatible with Call Waiting.
Caller ID
This feature sends identifying information about the calling number to the
called number. This can include: the calling telephone number, the name in
which that number is listed, the date, and the time of the call.
The amount of information that will display on the Caller ID device depends
on how the feature is programmed. For example, if you have entered *50#2#,
the box will show the maximum amount of information: the calling number,
name, date, and time of the call. (For more information, see command 50 in
Chapter 6).
Caller ID and Distinctive Ringing
Since there are circumstances, such as privacy blockage, an out of area call, or
a transmission error, in which Caller ID is blocked, the TLS-5 simulates these
events. (See command 50 in Chapter 6 and Caller ID Prefixes in Chapter 4 for
more information.)
Note:
If you change the distinctive ringing cycles, remember that a
three-second silence is required for the Caller ID information to be sent.
Caller ID with Simultaneous Calls
If two calls are made at the same time, the Caller ID is sent to the first line
before the second line rings.
Visual Message Waiting
Visual Message Waiting (VMW) is an on-hook signal that is issued to a line
when there is a recorded message waiting to be picked up. The FSK signal
typically turns on a visual indicator for the user to see. This feature is sent
when the line number dialed is preceded by a *50 (ON) or *51 (OFF) dialing
prefix. No ringing is sent to the called line, but the FSK transmission is sent.
Also, a three burst stutter dial tone is heard on the line called until the caller
dials the audio port number to simulate the pickup of a stored message.
