[EAS] Main Studio Question

I can tell you how we do it. We have a transmitter in Sacramento, but our studio is in San Francisco. (we also have a studio in Sacramento) We have an Intraplex with a VF25, four port audio card. We receive AM, FM and NWS at our Sacramento transmitter and send it back to the Sage at the studio in SF. It has worked extremely well. Though not high fidelity, it sounds good enough for EAS. For the first 10+ years we used a T1 to connect the Intraplexs. Now we use MPLS. We have ISDN and Internet for main audio backups.
The T1 became too unreliable and AT&T took a several days to repair it on more than one occasion. The MPLS has occasional maintenance windows, usually in the middle of the night, and occasional very short dropouts. Over all, I would say the MPLS has been much better than the T1. It also costs us about half of what the T1 cost. Over the last 13+ years we missed a few EAS tests when the T1 was down, but since we have a national Primary Entry Point connected to a fourth input on the Sage in SF we are covered for any EAN or NPT.

If my main Studio is a thousand miles from the transmitter, and there is no room at the transmitter site for the EAS equipment, how do you get the audio from the EAS designated stations to the transmitter?

Some suggested stream, and that was my first thought, but if the main studio's internet goes down, you lose all of your sources. ENDEC and the two stations.
