Introduction of Wide-Band Communications in the Telecommunications Network

An increasing demand for digital wide-band business communications has been emerging as a new driving force in the evolution of the telecommunication network. In parallel with this demand, new transmission, multiplexing, and switching technologies are becoming available to support the implementation of attractive end-to-end wide-band services. This paper looks at the application opportunities of wide-band technologies in the telecommunication network for both near and longer term use, and discusses key implementation and evolution issues. The paper also defines a wide-band channel structure plan as a basis for wide-band ISDN standardization.
