Abstract
When two 56K server modems communicate with one another over the public switched telephone network, they signal each other so that they communicate data to each other in a digital pass-through mode whereby essentially there is a direct digital connection between the two modems. This is accomplished by using extended ITU-T Recommendation V.8 protocols.
