How to connect DTMF/voice Analog resources to the B channels in ISDN simulation

Clarinet Run-time simulation allows to manages analog resources to be connected to after the establishment of the communications.

Connecting the unit and setting the test conditions:

The connections of Clarinet-Book USB units and the settings of test conditions for a basic simulation are detailed in the following pages:

Profile resulting from the wizard is ready for generating one outgoing call and accepting incoming calls in ISDN Simulation.

Transmit / Receive DTMF over the B channel established by Outgoing call COM#1

Edit the profile resulting from selection by the wizard in the template list:

  •  access to Generator èCOM#1  èEdit and select Active source = Cofidec 1
  •  access to Interface-Spec... èAnalog  and select:
    • DTMF 1 Cofidec 1
    • Cofidec 1 DTMF 1  
    • DTMF 1 freq = <value> 

Saving the profile:

  • ProfileèSave asèfilename.acp.

The DTMF1 tone <value> will be transmitted continuously after the establishment of the B channel. The DTMF tones received in the B channel are decoded and reported by DTMF events in the event file.

Transmit / Receive DTMF over the B channel established by an Incoming call

Edit the profile resulting from selection by the wizard in the template list:

  •   access to Responder èActive source  èConnect and select:
    • In column "Then Connect Active source" = Cofidec 1
  •   access to Interface-Spec... èAnalog  and select:
    • DTMF 1 Cofidec 1
    • Cofidec 1 DTMF 1  
    • DTMF 1 freq = < value> 

Saving the profile:

  • ProfileèSave asèfilename.acp.

The DTMF1 tone < value> will be transmitted continuously after the establishment of the B channel of an incoming call. The DTMF tones received in the B channel are decoded and reported by DTMF events in the event file.

Transmit DTMF over the B channel established by any Incoming call

Edit the profile resulting from selection by the wizard in the template list:

  •   access to Responder èActive source  èConnect and select:
    • In column "Then Connect Active source" = Cofidec 1
  •   access to Interface-Spec... èAnalog  and select:
    • Cofidec 1 DTMF 1  
    • DTMF 1 freq = < value> 

Saving the profile:

  • ProfileèSave asèfilename.acp.

The DTMF1 tone < value> will be transmitted continuously after the establishment of the B channel of any incoming call.

Connect Handset over the B channel established by Outgoing call COM#1

Edit the profile resulting from selection by the wizard in the template list:

  •   access to Generator èCOM#1  èEdit and select Active source = Handset

Save the profile:

  • ProfileèSave asèfilename.acp.

The Handset (connected to the socket "Handset" of the Clarinet Book) will be transmitted continuously after the establishment of the B channel.  The speech received by the microphone is transmitted to the B channel, the speech received from the B channel can be heared in the speaker.

Connect Handset over the B channel established by an Incoming call

Edit the profile resulting from selection by the wizard in the template list:

  •   access to Responder èActive source  èConnect and select:
    • In column "Then Connect Active source" = Handset

Saving the profile:

  • ProfileèSave asèfilename.acp.

The Handset (connected to the socket "Handset" of the Clarinet Book) will be transmitted continuously after the establishment of the B channel of an incoming call. The speech received by the microphone is transmitted to the B channel, the speech received from the B channel can be heared in the speaker.
