Re: remote radio via cisco routers..

Re: remote radio via cisco routers..

Then it's down to observing diagnostic output of each router as you assert the COR signal to see if it is acting on it or not. If so, then observe the other router to see if it is responding to the asserted signal. Try M-lead signaling. Try different things. I don't know what else anybody could do a...

Re: remote radio via cisco routers..

E&M is an ancient signaling protocol designed for telephone lines and therefore assumed d.c. connectivity from end to end. So E&M uses current loop detection in the same way that d.c. remote controls for radios operate. If their documentation shows it, then it must be safe. The -48 Volt supp...

Re: remote radio via cisco routers..

I think you must "key up" the channel to allow audio to be transmitted. I don't think it's nailed up full time so you would assert the M-lead to simulate radio COR by connecting it to SB. Best to consult the Cisco documentation on their web site for this. For Type 2 the Cisco docs say to c...

You have your routers "talking to themselves". I recommend using a more complete dial plan to keep sane. For example, right now on Router 2 you have port 1/1/1 calling itself via "connection trunk 200". So when the E-lead is asserted on Router 2 port 1/1/1 it "dials" 20...
