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

Analog signals 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.
