The French telephone wiring (and faster internet)
by RobertArthur • Fri 17 Jan 2020 23:00
To answer a question today in another forum I recycled a rather lengthy article I wrote several years ago about telecom issues in France. Only the part that describes the wiring colours and adsl/internet problems. It's a quick summary about the traditional telephone wiring here in France. Not addressing in depth the communication network as it made it's appearance in the French electrical code NF C 15-100 with it's major overhaul in 2002. Because I still do believe in information sharing, the world wide web has become a commercial market place, here a link to only three pages. Might also be helpful to speed up a slow adsl internet connection.

To continue: around 2028 the Plain Old Telephone System (POTS) will be something of the past. The French Telecommunications Authority (ARCEP) has published this timeline.

Gist: a gradual technical shutdown, as from November 2018 no new analogue lines, as from November 2019 no new RNIS (ISDN) lines. Orange will effectively shut down the PSTN technology from the end of 2023, region by region. ARCEP requirement: before switch-off Orange has to announce at least 5 years in advance the regions concerned in order to give all operators and users time to migrate to another technology. Where, when, are you being served already? This is Orange's map of France.

Dumping the old system has also consequences for clients who don't want internet but want to keep their téléphone fixe. The problem with adsl service is the maximum distance over your pair of copper wires to the local telephone exchange, about 6 km. Using the slower re-adsl protocol - limited bandwith (500 kHz), a few dBs more signal power - you reach the perimeter limit at 7 km. So the solution of Orange, giving these loyal customers a software crippled Livebox (voice only), leaves those further away in no man's land between the trenches of copper wires and mobile networks. With the now old fashioned analogue low-frequency signal (only 3 kHz) it is easy to carry the telephone signal to clients living 10 km or more from the exchange.

Not only internet problems, also voice problems in la France profonde. Nobody talks about it, even the French consumer organisations seem to be cut off from this simple technical reality.
