i'm attempting to figure out the difference in the SLATER tones that we hear... they are not the different old-school QCII tones that would define which house to light up, but something else... which seems to be consistent for 2 types of call.
from what i can tell, a steady 5sec 650hz tone is always some form of medical call sending out an ambulance, maybe an engine to assist as well, but always a XXX7 truck.
then every so often i'll hear and on/off tone at a different Hz (haven't figured out what Hz yet), and that seems to be calls which are not medical and do not involve an ambulance.
if i am wrong about any of this - someone please correct me.
i assume that just before this happens some kind of data packet goes out to tell each house or specific apparatus to open their speaker and so on... wish i knew what this was, it would be interesting to set up an old XTS or Unication system just to trigger for the departments close to me.
for now... does anyone know if i'm right about this 650hz tone, what the other tone is, and what differentiates them all (or tells which department to head out)?
thanks,
Richard
