The local access loop is undergoing a revolution. The copper infrastructure, which was built to carry telephony traffic, and has also been used extensively for baseband modem communications, now has the potential to be the platform for radically different services. These services can offer subscribers capacity which is orders of magnitude more powerful than before, and can give providers the opportunity to generate substantial additional revenues from their most valuable asset - the copper lines.
In this section we explore this revolution and see why it has a significant impact on the approach to managing the local loop.
