AC International MTA128ST-USB Manual De Usuario

For quick setup, the MTA128ST-USB includes six Quick Setup Factory Profiles, each of which is
configured for a specific type of port operation. You can load a Quick Setup Factory Profile into active
memory by using the command 

&Fn, in which n is the number of the profile you wish to load. If you

wish, you can then customize the profile and store it, using the 

&W command, so that it loads

automatically when the MTA128ST-USB is turned on or reset. These profiles are stored in permanent
memory and are not user-configurable as such.

Profile 0—Modem-like operation (default)

Profile 1—V.110 async operation

Profile 2—V.120 async operation

Profile 3—X.75 async operation

Profile 4—ML-PPP async operation

The following procedure assumes that you want to load, modify, and store Quick Setup Factory Profile
2 as your default configuration.

1.

Select the profile closest to the requirements of your application, in this case— Quick Setup
Factory Profile 2.

2.

In terminal mode, type 

AT&F2 and press ENTER. Quick Setup Profile 2 loads into the MTA128ST-

USB’s active memory.

3.

Enter any additional AT commands that you need to customize the selected profile to your
application (see Chapter 4, 

AT Commands, S-Registers, and Result Codes).

4.

Type 

AT&W0 and press ENTER to save your customized port configuration.

5.

Your customized profile now loads automatically whenever the MTA128ST-USB is turned on or
reset.
