Alternate solutions for cabling systems in both residential and business environments

摘要

This paper describes the cabling systems defined by France Telecom for offering the high bit rate services such as xDSL (Digital Subscriber Line) in residential and professional environments. The first part of the document describes the cabling offers proposed to residential and professional customers, ranging from the simplest dedicated for customers wishing the analog phone service only to a cabling offer with optical fibers. Solutions for ADSL "distributed filters" or "master filter" are proposed as well as solutions for the ISDN. New technologies (such as HomePNA, Powerline or radio) are introduced to enable several terminals in the house to be used, with a simple initial installation. Some more comfortable offers are described to realize a RAN (Residential Area Network) or a LAN (Local Area Network). The second part of the paper deals with the implementation of these various cabling systems offers in a laboratory and in the field. These experiments can be technical but also commercial. Some of these experiments are performed in our laboratories or on the test platforms at the Lannion site and others are commercially deployed on customer sites, in the Paris region for example.
