Title: ISDN Multicast
Post by radiorad on Feb 7^th, 2007 at 2:06am

Great forum.

I work in radio and I need to do a live ISDN multicast to about 20 radio stations. I will be at a remote location (Vegas) and its going to be pricey to get 20 ISDN lines to my location. Each of the radio stations will have either a Prima, a Zephyr or something similar.
Can this be done with AudioTX ?
I believe Primas can feed 6 line similtaneously - perhaps 4 Primas would be the way to go.
Any ideas would be appreciated.

Thanks

If you can go mono you can only order 10 ISDN lines.

You will need at least one B channel per connection no matter what codec you have.

In theory you could save some money by getting a PRI instead of a 20 BRI but you will need additional equipment in that case.
