Abstract
Existing local networks of copper-pair cables provide a medium for digital transmission between subscribers and their local telephone exchange. Transceivers for this medium have undergone a remarkable period of development stimulated by the promise of universal digital communications at rates of 64 kbit/s and above and enabled by rapidly advancing very large scale integrated (VLSI) circuit technology that now allows hitherto unimaginable circuit complexity at low cost, low power consumption and small size. The history of this change and its interaction with standardization processes forms the backdrop of this chapter, which is mainly concerned with the technology of local loop transceivers, especially for the important American National Standards Institute (ANSI) interface standard for integrated services digital network (ISDN) basic rate access. The ANSI standard is outlined and critically appraised and the impact of modern silicon technology trends is assessed on the dichotomy between standardization and functional diversity.
