Command Modem Operating Procedures

A wide variety of autodial operations and modem options can be controlled when the command modem is in the command mode. Command modem access commands are described in Chapter 5. Appendix D describes the general AT commands in detail.

Table 6-3. Command Modem Operating Procedures

StepProcedure

1Set your supervisory console to 2400 bps or less to communicate with the command modem. Execute the Command Modem Select command by entering the following:

AT#MA1 (hit Return)

The following will be displayed on your supervisory console when connected and in command mode:

COMMAND MODEM ACCESS ON
You may now enter the commands for the command modem as	described in Appendix F.

2You can have the "Result Codes" displayed in a “verbose” format (complete English words), or in a “terse” format (single digit numbers). The factory default format is verbose. To change to terse format, enter the Result Code Digit command as follows:

ATV0 (hit Return)

You can also choose to completely eliminate the display of all Result Codes by executing a Quiet (Q) command.

Before dialing your remote MultiMux, make sure that it is ready to accept calls through its command modem by having its 8-position DIP switch SW4 set to the OPEN (UP) position.

3Dial the phone number of your remote MultiMux. To dial a phone number, use the Dial (D) command. You can use Tone (T) dialing or Pulse (P) dialing and insert Automatic Pauses in Dialing (,) for functions such as dialing through a PBX switchboard. Refer to Appendix D for detailed descriptions of dialing commands.

For example, enter the following to dial a phone number (555-1212) through a switchboard.

ATD9,5551212 (hit Return)
When a carrier signal is detected, the Connect (1) Result Code is displayed.
If no carrier is detected, the No Carrier (3) Result Code is displayed after	about 30 seconds.
