Paradyne 3800PLUS manual Change Directory, AT Command Equivalent

COMSPHERE 3800Plus Modems

For example, under normal dial backup conditions, when a problem occurs on the leased line, the modems establish a connection over the dial network using a telephone number stored in directory location 1.

Call Setup:

Dial Standby

F1 F2 F3

When this occurs, the Dial Standby function now appears on the LCD. By selecting this function, the modem switches back to the leased line while still maintaining the dial connection. As a result, the Return to Dial function now appears on the LCD instead of Dial Standby.

Call Setup:

Return_to_Dial

F1 F2 F3

If the leased line is found to be unacceptable, select Return to Dial which switches the modem back to dial network operation (LCD displays Dial Standby). If, however, the leased line is operating properly, you can select Disconnect from the Call Setup branch and drop the dial-line call.

To access Dial Standby or Return to Dial from the Call Setup branch, make the following selections:

Call Setup:

Dial Standby

F1 F2 F3

Press the key until Dial Standby or Return to Dial is displayed. Select the appropriate function.

Dial Standby

Command Complete

F1 F2 F3

If the modem is operating in a Dial Backup mode, the Dial Standby function forces the modem to leased lines and displays the status message Command Complete.

Once the modem is in Dial Standby mode, the Return to Dial function appears on the LCD. Selecting this function forces the modem to dial networks and displays the status message Command Complete.

AT Command Equivalent

There is no AT Command equivalent for Dial Standby or Return to Dial.

Change Directory

Change Directory allows you to enter or modify telephone numbers. The modem has nonvolatile memory locations that allow you to store up to 10 telephone numbers. Each directory location can accept up to

40 characters; this includes the telephone number and dial command modifiers. Any telephone number dialed using the DCP Dial command must appear in a directory location.

NOTE

If the modem is operating on leased lines and has a dial line attached for dial backup purposes, it is required that directory location 1 contain the telephone number used for dial backup.
