OPERATING THE MODEM FROM THE FRONT PANEL
The front panel menus are organized functionally so that operation is easy for novice and advanced users.
Refer to Chapter 3, Getting Started, to learn about front panel operation.
SELECTING PROGRAMMED OPTION SETS
Option sets make it easy to use a modem with common applications, including:
•
Asynchronous and synchronous answering
•
Asynchronous and synchronous dialing
•
Leased line with dial restoration operation
Four sets of options are stored in nonvolatile memory. If none is appropriate to an application, you can
customize an option set, and save it in nonvolatile memory.
Refer to Chapter 4, Configuring the Modem, for more information on option sets.
AUTOMATIC CALLING INTERFACES (ACUs)
The modem supports three automatic calling interfaces (also known as Auto-Call Units). ACUs let you execute
functions from a keyboard.
AT ACU
The asynchronous
AT ACU
is compatible with the industry-standard AT command set. AT Commands
provide a standard modem communications interface, allowing you to configure and operate your modem
from a terminal or PC keyboard.
Using the AT-compatible command set (AT and AT&), you can, for example, dial and receive phone calls.
Raymar-Telenetics’ extended AT command set (AT
*
) includes other important parameters used in
configuring advanced modem features.
Refer to Chapter 3, Getting Started, and Chapter 5, Using the AT Automatic Calling Interface, to learn more
about the AT ACU and AT command syntax.
V.25bis ACU
For sync or async auto-calling, use the ITU-T V.25bis compliant ACU.
With either the AT or V.25bis ACU, you can store, dial, or change up to nine phone numbers in the
modem’s electronic telephone book, directly from your terminal.
Refer to Chapter 3, Automatic Calling Interfaces, in the
326X Series Modem Reference Guide
, for details.
