INTRODUCTION
This section of the manual describes the Autopatch features in your controller. We use the term
Autopatch to describe a telephone call originated by the repeater user. Reverse Patch calls,
originated by a telephone user, are described elsewhere in this manual under the heading Landline
Control.
The autopatch can be accessed in several ways:
(1) You can manually enter the required DTMF digits via your radio's DTMF keyboard. You can
program the controller to require an autopatch password ahead of the telephone number, or you
can program the controller to only require the telephone number.
(2) You can manually enter a macro name via your radio's DTMF keyboard. This previously-
programmed macro would contain the autopatch password and telephone number as described
above. The macro feature requires far fewer digits to be entered to dial the autopatch, but you
must store the numbers you wish to dial into macros before you can use the macros.
(3) You can program the COR Pulse Triggered Macro feature to execute one of the macros
mentioned in (2). Then, a user would only need to key his 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.
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 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:
1. There is never a prolonged dial tone that results from a user entering the "*", then
not placing a call.
2. Since the controller regenerates all DTMF digits going to the telephone line, noisy or
inaccurate tones from the receiver cannot cause misdials.
3. 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 autopatch access command is completely self-contained.
Therefore, any other command can be entered before or after an autopatch access command.
Other commands that you might want to use during an autopatch include Dump, Re-dial, Timer
Reset, or even a new access command. (Entering a new access command while already in an
autopatch will cause the original call to be dumped and the new call to be dialed).
