IMBE Link

This is the working page for IMBE Link.

Features

1.0

First version, needs to incorporate the basics of PNXmono, but in a modular format.

• config file in a traditional unixy format. No stupid C# bullshits
• Support for p25 data via STUN to cisco doing HDLC to the 9600 bps quantar v.24 interface.
• Two operational modes
  • Traditional link, where the quantar does local repeat and the application handles network linking.
  • Base station mode, the quantar does not repeat anything, the app repeats all data to the quantar, like an analog controller.
    • In base mode, it can limit encrypted audio locally too, or force rewriting of talkgroup/messages

• Support for talk group scanning
  • This would be a registration and priority matrix for individual talk groups
  • support for talk back with ability to define the hang time

• Ability to block encryption or allow encryption (force encryption?)

• Courtesy tones as files - allow them to be defined
• Proxy of v.24 frames, only the IMBE data should be passed to the Quantar, control data should be stripped out
  • prevents channel changes

• mute when RSSI/QOI value is below a given value (perhaps play a tone here?)

• stats collected and ASTRO ID recorded
• improved logging and debugging

• output status of system via named pipe/logic on pi.
  • this would be used to block the system on P25 only for a set period of time.
  • Could be accomplished via channel change too.
  • Ideally would make the mixed mode operation easier without as many wildcard functions.

2.0

• FDTI to Quantar v.24 interface.

• recording of conversations and metadata

• Bridge system
• * This would be a confederation of linking and registration servers to reflect the traffic

• System Wide Stats dashboard

3.0

• Asterisk channel driver
