DTMF Commands

This chapter describes the Dual Tone Multifrequency (DTMF) commands that apply to the basic telephone service interface on the router.

Note The command syntax includes a combination of bold and regular uppercase and lowercase alphanumeric characters. You can enter commands in full or you can enter abbreviated forms of many commands. The abbreviated form consists of the first characters in each word of the syntax that appear in bold uppercase type in command syntax in this chapter. These characters represent the minimum you must enter for the command to be recognized and executed.


DTMF Command Conventions

These configuration commands are entered from the telephone keypad to enable a limited set of parameters. To enter DTMF commands you must first press the * key twice followed by the two digit designator for the command. After entering the command, press the # key to terminate the command. The following is an example of a DTMF command: 

**sw#

After the command is terminated (with the # key) the router processes the command. If the command has been entered properly and is being processed the phone LED on the router will blink rapidly. If the command is entered in error, the phone LED will blink slowly, over an extended period of time.

Note These commands apply only to routers with analog phone support. These commands should be performed before connecting the router to the ISDN line.

fig_1.gif Caution Do not perform these commands on a terminal connected to the router. You must perform these commands on the telephone keypad of the device that is connected to the router through the basic telephone service port.
