A method, apparatus, computer product and structure is presented for representing and managing large amounts of information concerning networks of elements. While being useful for communication networks, it can be also usefully deployed in the context of other networks such as distribution and transportation networks. The method uses a hierarchical construct called 'catalog'&#x2014;a set of elements (which could be 'atomic' elements or catalogs themselves)&#x2014;to organize information about physical or abstract entities relevant for modeling the network. A matrix construct whose rows and columns constitute such elements are used to model connections at different levels of abstraction. A common framework and representation provided using these two constructs is shown to be useful for visualization, administration, configuration, modeling, monitoring and manipulation of the network.

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.

Modem protocol

The invention is an ISDN terminal equipment which will maintain connectivity with existing analog modems by setting up a voice-grade connection to existing analog modems and using the power of a digital signal processor DSP to generate the digital equivalent of the analog modem signals for transmission on an ISDN 'B' channel.
