How and what are they used for?
I wrote a new code plug today on depot for my xts2500 and it gave me the options to add those options to my flash code.
Fireground Accountability provides visibility to the incident commander via electronic & automatic identification of the on-scene personnel via portable radios. The incident commander or other individual in charge would have a tablet or computer with software that can see radio location and other info such as Radio Alias, emergency alarm indication, Channel indication, battery indication, power down indication, roll call, evacuation tones, and manual and automatic polling. It is also NIMS Compliant.
FDNY Emergency Rx/Tx Tone Set enables a tone signaling format called ATIS (Automatic Transmitter Identification System) which was used specifically by the FDNY. This tone set sounds simular to MDC but the two systems are not compatible. FDNY uses TPS on the fireground (UHF-T) radios. Each radio is assigned an ID based on the company and the riding position. For instance 2240001 could be Ladder 24, officer. 2240002 hookman, etc. I believe its unit type, company number, division, etc. The Command Tactical Unit has the software that will display the radio ID's and is interfaced to the shift roster so that if Lt Smith came on shift, it would display all of that.
Additionally the tone set option changes the way the user hears an emergency datapacket. I really forget what it sounds like, but I think with recent ASTRO25 and APX firmware its the same/simlar to the high/low tone that these radios now emit.
Both are pretty useless without the proprietary software that makes them work.
Hope this helps!
