Figure 24 DTMF Key Pad

4.10.4.1 Send Button

The Send button sends the digits entered in the DTMF digit window out to the select device (encoder or decoder)

4.10.4.2 Clear Button

The Clear button allows the operator to delete all the digits entered in the DTMF digit window.

4.10.4.3 BK SP Button

The BK SP button allows the operator to delete the last digit entry from the DTMF digit window.

Encoder Radio Button

When the Send button is selected and the Encoder radio button is active then the digits in the DTMF window are

sent from the encoder across the channel. A the other side of the channel the information is decoded. The encoder

and decoder radio button can not be active at the same time. The encoder passes the DTMF data in-band (within the

regular voice data bits) so that normal DTMF tones pass seamlessly from the encoder to the decoder. The decoder

synthesizes a DTMF tone in response to reception of an in-band DTMF tone data in the frame.

4.10.4.4 Decoder Radio Button

When the send button is selected and the Decoder radio button is active then the Net-2000™-VCU sends tone

directly to the local decoder to output the digits as entered in the DTMF digit window. The decoder and encoder

radio button can not be active at the same time.

Selecting the Close button closes the DTMF pop-up window.

4.11 Channel Settings

The Net-2000 can be configures to encode / decode speech from one of three communications channel sources. The

default channel is Ethernet loopback. Only one communication mode may be selected at a time. After switching

from one communication mode to another it is necessary to select the start button in order to initiate the change.
