ISDN Bridging

The nonprofit clinic I work with uses ISDN for telemedicine. They use ISDN bridging to connect to providers that have IP equipment, but the provider for this service is quitting the business. I have found commercial providers but they are very expensive for a nonprofit. Is there some piece of equipment that would convert our ISDN outputs (I believe it uses 2B+D) to our network so we could use our internet connection to connect to IP equipment ?

I don't understand what you are wanting. Your ISDN modem/router should be providing this function (ISDN to IP). Are you currently using your ISDN to connect to the Internet? Or is your ISDN used to connect directly to another medical location?

We have teleconferencing equipment that connects only by ISDN and has no connection to our local network or the internet. To connect to IP equipment, we place an ISDN call to the bridging service. We need somehow to replace this bridging service.

Can you post some info on your teleconferencing equipment? Make, model, Internet link?

Our equipment is pure ISDN. There are 3 cables that plug into the ISDN wall socket. More details will have to wait until Monday. The internet link is made by placing an ISDN call to our ISP, which is what we need to replace, hopefully by some piece of equipment which will connect to the ISDN cables from our equipment and transform the output to TCP/IP over ethernet which we could then use over our local internet connection.

What you are wanting is to replace the Telco switch with one you own -- in other words use a piece of ISDN equipment without an ISDN line. There are SDSL modems which do this but I have never of anything similar for ISDN.

A possible solution would be to get a second ISDN line and attach the appropriate equipment to it and our network (would that be an ISDN router ?) and call it from our teleconferencing. This seems ugly, but should work and might be cheaper than other solutions.

That would work. One thing you will need to consider is to make sure that it would be compliant with HIPPA. Without knowing more about what your provider is currently doing I want to throw that caution into the discussion.

I was thinking about what you said here and from what I remember, these ISDN teleconference units use 3 ISDN lines -- hence the three cables.

Your best solution may be to discard the ISDN based system and go to an IP based videoconferencing system. What kind of expenses are you currently incurring with the ISDN lines and how much are they wanting for the ISDN bridge service?
