040: Send One or Two Tone Sequence

This command causes a tone "sequence" to be sent out the ports specified by the routing variable

(see Appendix A for information about the routing variable). A "sequence" is composed of one or

two tones which are generated simultaneously for a specified duration and followed by a specified

pause. Most courtesy beeps use only one tone at time, although many have several tones in

sequence. This type of courtesy beep would be generated by calling this command several times

from a macro, sending a one-tone chord each time (see examples on the following pages). DTMF

digits and dial tone are familiar two-tone combinations, and can be easily generated using this

command.

Sequence Command Type

Single Tone <040> ttt ppp ffff

Single Tone <040> tttt pppp ffff

Dual Tone <040> ttt ppp ffff gggg

Dual Tone <040> tttt pppp ffff gggg

Parameters:

- TTT or TTTT is a number representing the length of the tone in 10mS increments. If you use

four digits for the length of the tone, you must also use four digits for the length of the

pause. The tone length is limited to 60 seconds (6000).

- PPP or PPPP is a number representing the length of the pause to follow the tone in 10mS

increments. If you use four digits for the length of the tone, you must also use four digits

for the length of the pause. The pause length is limited to 60 seconds (6000).

- FFFF is the frequency of the primary tone in hertz. All four digits must be entered.

- GGGG is the frequency of the secondary tone in hertz. All four digits must be entered. It is only

used when you want both tones active at the same time, like a DTMF tone. If you want a

beep at one frequency then a beep at another frequency, call this command twice from a

macro and only specify one frequency each time.
