There are several companies now doing this. I have worked with Micom (800-MICOM-US) and Republic Telecom equipment. Timeplex, Stratacom and others do this now as well. Recently a couple of companies have advertised in _Data Communications_ and _Network World_ small, modem sized stand alone units. The names escape me at the moment... > If such a single unit or multiple units exist, can they support OPX > (Off Premise Exchange) and SLT (Single Line Telephone) type interfaces? > (I'm assuming OPX and SLT are valid interfaces.) Most any type of line, with the proper signalling modules, can be supported. Most of those units accomodate either in-band or out of band (part of data stream) signalling. > Any information that can help me identify integrated circuits or > actual commercially available hardware (now or in the near future) > will be greatly appreciated. Sorry, I only work with assembled units, so I can give no codec info. You can give be a call at my office (216) 778-6233 (Cleveland) to discuss this ... or use macy@ncoast.org Macy M.
