ConnecT 56K DSU User Manual

Configuration methods

The ConnecT 56K DSU provides four different methods for local

configuration and three different methods for remote configuration:

1. Front Panel

2. AT Commands

3. V.25 bis

4. Remote Commands

The Front Panel provides access to all operation parameters of the

ConnecT 56K DSU through a multi-level menu structure which begins

with the four-part Main Menu. (See Chapter 3).

In addition to the front panel, the ConnecT 56K DSU can be configured

and controlled with in-band AT commands from an asynchronous DTE

port just as modems are.

To exit the data mode and enter the command mode, the asynchronous

DTE device must transmit a proper escape sequence to the ConnecT 56K

DSU. A specified time delay must occur between the last data character

and the first escape sequence character. This is the guard time delay, and

it can be changed by writing a value to the S12 register. The default value

for the guard time is one second. For a valid escape sequence to occur, the

DTE must transmit the escape code character three times in succession

with delay between each character being less than the guard time.

1=STATUS Displays status of network and DTE interface

2=TEST Controls local and remote testing

3=CONFIG Displays/changes current configuration parame-

ters

4=DIAL Provides manual dialing functions (available only

when unit is configured for SW56 operation).
