DTMF Commands

---

This chapter describes the dual tone multifrequency (DTMF) commands that apply to the basic telephone service interface (PHONE1 and PHONE2) on the router.

---

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 ports (also known as plain old telephone service or POTS ports).

---

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 2-digit designator for the command. After entering the command, press the # key to execute the command. The following is an example of a DTMF command:

**sw# 

*	Represents the * key on the telephone keypad.
#	Represents the # key on the telephone keypad.

If the command has been entered properly and is being processed, the telephone LED on the router blinks rapidly. If the command is entered in error, the telephone LED blinks slowly over an extended period of time.

---

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