E1/T1 (Trunk/ISDN/QSIG/SS7) & ISDN-BRI Interface Specifications

- ANALOG

Analog signal switching: between inputs and outputs (INPUT OUTPUT) of analog resources.

  • INPUT The related analog resource (on the left side of the arrow) receives an INPUT signal:
    • DTMF 1: DTMF resource number 1 used to decode the Q23 dual tone.
    • DTMF 2: DTMF resource number 2 used to decode the Q23 dual tone.
    • Analog I/O 1: Linked to Analog Output 1 available on the I/0 connector.
      * Not supported by Clarinet-Book USB type.
    • Analog I/O 2: Linked to Analog Output 2 available on the I/0 connector.
      * Not supported by Clarinet-Book USB type.
    • Handset speaker 1: Linked to Speaker output (combination of speakers 1 and 2 ) available on the HANDSET connector.
    • Handset speaker 2: Linked to Speaker output (combination of speakers 1 and 2 ) available on the HANDSET connector.
    • Cofidec 1: Analog input of the Cofidec 1.
    • Cofidec 2: Analog input of the Cofidec 2.
  • OUTPUT: The selected analog resource (on the right side of the arrow) generates an OUTPUT signal:
    • None: No item connected.
    • DTMF 1: DTMF resource number 1 used to generate a frequency signal either a Q23 dual tone or a single tone.
    • DTMF 2: DTMF resource number 2 used to generate a frequency signal either a Q23 dual tone or a single tone.
    • Analog I/O 1: Linked to Analog Input 1 available on the I/0 connector.
      * Not supported by Clarinet-Book USB type.
    • Analog I/O 2: Linked to Analog Input 2 available on the I/0 connector.
      * Not supported by Clarinet-Book USB type.
    • Handset micro: Linked to Microphone input available on the HANDSET connector.
    • Oscillator: Frequency signal. Not used.
    • Cofidec 1: Analog output of the Cofidec 1.
    • Cofidec 2: Analog output of the Cofidec 2.

DTMF1 freq: Selection of the frequency signal (either Q23 dual tone or single tone) sent by the  DTMF resource number 1

DTMF2 freq: Selection of the frequency signal (either Q23 dual tone or single tone) sent by the  DTMF resource number 2

Oscillator freq: Selection of a frequency signal. Not used.

Cofidec(s)... For digital connections between the Cofidecs and some TS's of the current interface.
