EAGLE

Multi-Standard Dual-Channel Digital Audio Codec

4.19 DTMF tones generation.

The AEQ EAGLE is able to generate DTMF tones in both audio circuits, in all audio modes,

except for those using MPEG Layer 3. It can generate the tones locally, through the front panel,

or remotely, using the “Eagle Real Time Control” software.

To activate the DTMF generation mode and generate tones, follow the next steps:

1) Once communication has been established, leave the ‘*’ key pressed for 5 seconds. DTMF

mode should be activated and a ‘D’ will appear on the DIAL display. DTMF tones can now

be generated on either C1 or C2, by pressing over the keypad. The cursor arrows under the

Setup display are used to choose which channel generates the tones.

2) In MPEG L II 128 MONO, DTMF tones could only be sent through C1. In MPEG LII 128

STEREO and DUAL, tones can be sent through both channels.

3) To exit DTMF generation mode, press any of the keys under the DIAL display or the

ON/OFF keys.

DTMF is not available for all those modes using MPEG Layer 3.
