Courtesy Tone
A Courtesy tone is a short prompt tone that is sent just after the mobile unkeys to prompt the other
party to begin speaking. It is also sometimes referred to as an “Over” prompt or beep. The Courtesy
tone is a 1200 Hz tone with a duration of 50 milliseconds. It is enabled or disabled on a per user
basis.
How to program it:
Access the Model 748 through your direct connected PC or terminal, or remotely from your PC
connected to a modem via the Model 748's internal modem.
Once connected to the Model 748 and the Main Menu is on the screen, type “1” and press ENTER ,
and the Interconnect Menu will appear. Type “3” and press
ENTER
, the User Menu will be
displayed using the currently selected user's data. Select the User number you wish to program (see
“User Range” later in this section). Select the item number for
Courtesy tone and press ENTER .
The currently selected mode or state will be shown along with a message instructing you to press the
space bar to change the mode or state, and to press
ENTER to accept the current mode or state. Each
time the space bar is pressed, the mode or state changes. Once the mode or state you desire is
displayed, press
ENTER
to accept it. Note that if you accidentally pass the mode or state you want,
keep pressing the space bar and the Model 748 will wrap around (when the last choice is displayed,
it will return to the first one).
The default for Courtesy tone is disabled or off for all users.
Courtesy tone is supported by block or range programming. See “User Range” later in this section
for details.
CTCSS/DCS Decode - CTCSS/DCS Encode
The Model 748 has the ability to decode and encode CTCSS or DCS for an interconnect call.
Decode is typically used for validation along with Access ANI during call setup. Encode is typically
used for selective calling a user or user group during call setup.
Decode can be used for answering calls, removing the need for DTMF to answer calls. It is also
useful in validating disconnect ANIs and audio gating to prevent barge in by impatient users.
Encode is can also be used in channel busy applications to keep the called radio unsquelched and
prevent others from barging in or initiating a call until the channel is again free.
The Model 748 is capable of decoding and encoding 50 CTCSS tone and 104 DCS codes. Refer to
“CTCSS Tones” and “Digital Squelch Codes” in Section 7 for a full listing of the supported tones
and codes.
