Signalig protocol

To types of signaling protocols used towards the stations, Current Signaling and Tone Signaling

Current Signaling

Digit Signaling

Station keyboard digits 0 - 9 use sinewave tones in the range 500Hz to 2300 Hz, at 200 Hz steps.

  • Digit 0: 500 Hz
  • Digit 1: 700 Hz
  • Digit 2: 900 Hz
  • Digit 3: 1100 Hz
  • Digit 4: 1300 Hz
  • Digit 5: 1500 Hz
  • Digit 6: 1700 Hz
  • Digit 7: 1900 Hz
  • Digit 8: 2100 Hz
  • Digit 9: 2300 Hz

Extended Digit Signaling

In addition to the keyboard digits 0 - 9 another set of 10 tones are used for DAK signaling for CRM IV, Dual Display and PrisCom stations.

These tones 10-19 are sinewave tones in the range 600Hz to 2400 Hz, at 200 Hz steps.

DAK Signaling

Master stations use a combination of current signaling (M) and digits:

  • DAK 1: M + digit 0
  • DAK 2: M + digit 1
  • DAK 3: M + digit 2
  • DAK 4: M + digit 3
  • DAK 5: M + digit 4
  • DAK 6: M + digit 5
  • DAK 7: M + digit 6
  • DAK 8: M + digit 7
  • DAK 9: M + digit 8
  • DAK 10: M + digit 9

CRM IV and Dual Display Stations:

  • D1-D10 M+0 - M+9
  • D11-D20 digit 10-19
  • D21-D30 M+10 - M+19
  • D31-D40 C+0 - C+9
  • D41-D50 C+10 - C+19
  • D51-D60 (Prefix +) M+0 - M+9
  • D61-D70 (Prefix +) digit 10-19
  • D71-D80 (Prefix +) M+10 - M+19
  • D81-D90 (Prefix +) C+0 - C+9
  • D91-D100 (Prefix +) C+10 - C+19

Two Tone signaling

The Two Tone signaling uses a combination of Extended Digit Signaling and Digit Signaling, and is used by the PrisCom Stations.

  • Key board digit 0-9
    • Digit Tone 0-9
  • DAK D1-D15
    • Digit tone 10 + 0 to 10 + 14
  • DAK D16-D30
    • Digit tone 11 + 0 to 11 + 14
  • DAK D31-D45
    • Digit tone 12 + 0 to 12 + 14
  • DAK D46-D60
    • Digit tone 13 + 0 to 13 + 14
  • DAK D61-D75
    • Digit tone 14 + 0 to 14 + 14
  • DAK D76-D90
    • Digit tone 15 + 0 to 15 + 14
  • DAK D91-D100
    • Digit tone 16 + 0 to 16 + 9

Optional DAK Acknowledge

If the station is configured with acknowledge on DAK keys:

  • The AMC application will send an acknowledge message by the Display Text Protocol.
  • The station will acknowled this by sending tone 18.
