Signalig protocol

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

Current Signaling

Single Tone Signaling

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

  • Digit 0: 500 Hz Digit 5: 1500 Hz
  • Digit 1: 700 Hz Digit 5: 1700 Hz


Another set of 10 tones are used for DAK signaling for CRM IV, Dual Display and PrisCom stations.

  • The tones 10-19 are sinus tones in the range 600Hz to 2400 Hz, 200 Hz steps.

Two Tone

Two Tone signaling 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.
