Your controller has many features that allow you to customize the operation of
the autopatch. The following discussion is simply an overview of autopatch
operation. Details begin on page 7-3.
Accessing the Autopatch
The Autopatch can be accessed in several ways:
• You can manually enter the required DTMF digits via you radio's DTMF
keyboard. You can program the controller to require an Autopatch Access
Password ahead of the telephone number, or you can program the
controller to require only the telephone number.
• You can manually enter a macro name via your radio's DTMF
keyboard.This previously-programmed macro would contain an autopatch
access password and telephone number as described above. The macro
feature requires far fewer digits to be entered to dial the autopatch, but
requires you store the numbers you wish to dial into macros before you can
use the macros.
• You can program the COR Pulse-Triggered Macro feature to execute one
of the macros mentioned above. (See page 16-4.) Then, a user would only
need to key his/her microphone PTT button several times to access the
autopatch and dial an emergency number. Only one number can be dialed
this way. Likewise, any of the Event-Triggered Macros can be used to dial
the autopatch by creating an "autodial" type of macro, then loading that
macro name into the proper event command.
Store-and-Forward Operation.
The autopatch dialer software uses Store-and-Forward Operation. This means
that the controller takes no action until the entire telephone number has been
entered. It then checks the number to see if it is acceptable. If acceptable, the
number is dialed using pulse (rotary) format or regenerated DTMF format. This
method is far superior to the older star (*) up patch, in which phone line access
is granted with just a DTMF (*).
The advantages of store-and-forward operation are:
• There is never a prolonged dial tone that results from a user entering the
(*), then not placing the call.
• Since the controller regenerates all DTMF digits going to the telephone line,
noisy or inaccurate tones from the receiver cannot cause misdials.
• The controller is never stuck in a mode where it must wait for a specific
command type to be entered before it can continue operation.
• In the store-and-forward scheme, every access command is completely
self-contained. Therefore, any other command can be entered before and
