Don't know if its legal to inject EAS into AOIP here.  CRTC might choke 
on that question. I'll ask and let you know the answer.

Here in Canada the national alerting system is all new and not having to 
support legacy EAS systems or protocols.  It is pretty loosey-goosey, 
not like on your side of the border, with much more legal definitions 
from what I understand.  Not many digital consoles here, especially in 
the community and remote rural markets, still analogue audio.  Best 
practice?  That is why I am asking this group, I've never actually 
worked at a real radio station, just a tinkerer from up north.  Having 
said that I started the first CRTC licenced commercial FM station here 
in the Klondike in 1997.

Hey Cool!
> To address your question The QOR is much less configurable than the PowerStation with an element or fusion control surface. We have a GPIO triggered by the framed contact on an ISDN unit that only lights the channel light when the ISDN is connected.  Pathfinder can also control many aspects of the element.
I did post this question to FB, user came back that it is possible to 
blank all the lights on a board.  Maybe there will be a way to 
toggle\cycle this a few times to get the attention of talent that is not 
paying attention to the station or actively monitoring the signal. I do 
supply scrolling LED signs for this purpose and seeking something that 
is already built into the consoles. Less is more.

Right SNMP.. I'll have some intelligent questions to ask Telos. Thanks.

Qor sends out an RTP stream to our player with a mix of mics/inputs and playout audio from the machine to an icecast mount point that is picked up by the Barix at radio transmitter site.

When immediate BI alert plays, a relay is triggered then the channel overrides in the QOR, plays the alert until the relay is reset and then resumes from normal source.   We have the capability to create an on demand RTP stream when an alert is issued for the Qor as a multicast address to detect and overide an incoming channel.
