Technical Reference for ZyXEL omni.net series

The commands or data are packaged. Each packet has its own destination address. All the DTE channels can be accessed individually by way of multiplexing.

AT Commands Description

An AT Command is a command in asynchronous data format issued by the computer to the ISDN TA through the asynchronous computer-modem interface. AT Commands control the ISDN TA behavior and actions. To send an AT Command from a computer to the omni.net, you must run a communication software program and the omni.net must be in command state.

Exceptions to the above requirement are [A/, A>, and +++.] These commands are neither preceded by the prefix AT, nor followed by any other character:

!A/ - re-executes the last command once.

!A> - re-executes the last command once. Also used to repeat the last call up to 9 times until aborted by pressing down any key on the keyboard or front panel or until a successful connection with a remote ISDN TA has been made.

!+++ - is the escape sequence code that is entered in data state to return the ISDN TA to command state. The omni.net will accept AT commands only while it is in command state.

AT Commands Prefix (AT)

All other AT Commands require the command prefix [AT]. The prefix may be typed in either upper 'AT' or lower case 'at'.

NOTE: Do not use a combination of upper and lower cases in the prefix.

The following tables list all of the AT commands supported by the omni.net LCD/Plus/D. An asterisk (*) following a command option or value indicates that it is a default setting when the omni.net is shipped.
