VOIP MODEM QUESTION, FOR A DRY PAIR

Hello,
Still havn't got a good answer to this. I am not interested in the DVSI or similar units that cost multi thousand dollars that provide radio over IP. I am shure that there is an easier, more cost effective way to do this.

What I am looking to do is create a "phone line" dry pair for a tone remote use over a network.

It will be used to transmit tone remote data only one way for RX purposes, but duplex wouldn't be bad.


Some one suggested that 2 VOIP modems would work, any ideas?

Yes I make such a product package it is not expensive. It uses a regular old computer as the D/A -A/D converter. The Codec has a very high bit rate and can sample and encapsulate your data, without loss, and transport it to either one iP address or Multiple addreses. Saves a ton of money over copper pairs/ leased t1 and is almost as reliable providing you have redundant power at both locations. We use it right now to link repeaters and full blown trunking systems together all over the world using the internet for a very economical price.

PM me if you have any questions

Go to the web site for Multitech. They make a series of Voip modems of which some will do radio control.

You might also look at JPS Communications NXU-2. It's more costly but also more applicable to radio control.

Be caution of having enought bandwidth and, this is important, low latency in your ethernet packets.

Good Luck, Bob
