ADSL at 20 Mbps / ADSL à 20 Mega

My DSL line came back online last night and a speed test with speedtest.net showed a throughput of 20 Mbit/s. I'm thrilled. I've gone ahead and made several changes to my network configurations here at home as a result.

I have a WAN router at home which patches together the DSL and cable Internet subscriptions. I can assign different applications to different networks or simply use it in "rollover" mode where the second line is used automatically when the first line goes down. In the past I've used cable as the primary connection but it was down more than half of the time so I was constantly getting cut off from VPN access when the access line switched. Now I'm able to use DSL as the primary connection and use cable only if the DSL line drops.

I'm excited to have the new, faster connection. It seems to really make a difference.

Switching the lines to the new exchange - Changement des lignes au nouveau NRA.

My house is now 797 meters from the DSLAM instead of 4,500. Sam pointed out in a recent blog comment that France Telecom has the new exchange up and running and that Free's DSLAM would be installed soon. I saw it today.

Now if only my line weren't dead so I could enjoy it.

My DSL connection went down yesterday at noon and has been out for 36 hours. My DSL provider (Free) is actually very stable but the line speeds have been very slow. My cable connection with Numericable is just the opposite - fast when it works but out of order more than 50% of the time.

If DSL goes down it's because they are doing something at the exchange. Any problem in the past I've had has been an inadvertent disconnection by FT. I knew something was up when my neighbor across the street came by with his Freebox to test it on my line because his line was down too.

I waited for my cable connection to come back up and then quickly hopped online to check the details of my line. What I found was great news. My line has been shortened by connecting to the new exchange. The bad news is something is wrong with the connection.

Then today I was driving home and saw the large France Telecom manhole at the edge of the village open with workers inside. My son and I walked down and talked to the workers, taking a few pictures of the manholes.

The workers were really helpful and let us snag a few pictures of them at work in the underground chamber. I was surprised by how large it actually was.

 

The next person I encountered we knee-deep in water in a second manhole working to reconnect some of the thousands of lines which have to be rerouted.

Then I walked the rest of the 797 metres and arrived in front of the actually exchange, which they call a NRA(HD). The France Telecom person there was very helpful and answered my questions about the fibre routing and how the exchange was upgraded. Simple telephone lines are still connected to the old exchange but any DSL lines in our village now terminate in the new village exchange.

I was able to snap a few pictures of the exchange with the door open from the fence. You can see the patch panels on the right but the DSLAM's aren't visible in the shot. They are on the left (Free and Neuf).

 

I was finally able to get through to Free to tell them my line was down. The earliest they will send a technician is in 7 days. That's a long time to go without our fixed line...

Upgrades at our exchange - Construction de notre nouveau commutatuer

I drove by the exchange in our village tonight and they've delivered a new building (actually a big rectangle box) and put it inside the fence of the exchange. It looks to be the size of a shipping container which sits on the back of a semi-truck.

I looked at the sign posted on the site which gives information about the proposed construction. It says that the old exchange is 11 square meters but will be upgraded to 25 square meters.

It looks as if they're making progress. That could mean faster broadband - but no fiber - pretty soon.

Too late for changes - Trop tard pour les changements

I received great advice from the Dutch about how municipal government should build the new exchange next year in order to promote competitive fiber development. The problem is I'm a bit too late.

I received word this weekend that the contract and negotiations with France Telecom were too far advanced for the municipality to be able to make changes. It's too bad that the village will be paying for the construction of the building (for France Telecom's benefit) but won't be able to dictate any new terms for fiber. I'm taken back that an exchange being built anywhere in the world in the year 2009 would lack space for competitive fiber equipment.

Hopefully other villages poised to give EUR 50,000 to France Telecom will be able to use the excellent advice I received from my Dutch friends to promote fiber competition in the future.

This means that I'll have to approach this a different way - possibly with a separate fiber shelter next to the copper exchange. Each of the competitive operators has fiber passing through the exchange already so we'd simply have to put the fiber shelter next to this line so they'd be able to interconnect easily.

I'll work on setting up a meeting with the competitive operators this week to discuss a plan.

Upgrading the exchange? / Travail sur notre NRA?

I was doing some research for work on Neuf/Cegetel today and decided to use my phone number as a way to look at the current offers. The site churned for a few seconds and then left this message:

Ligne en maintenance technique France Télécom a lancé une opération de maintenance sur votre ligne. Cette opération vise à déplacer la terminaison physique de votre ligne dans un autre central téléphonique. Lorsque cette opération sera achevée, d’ici une à six semaines, vous pourrez connaître les offres haut débit disponibles sur votre ligne. Nous regrettons cette situation et vous encourageons vivement à revenir tester l’éligibilité de votre ligne dans les prochaines semaines.

In English:

Line undergoing physical maintenance France Telecom has started maintenance work on your line. This operation will change the physical termination point of your line to another telephone exchange. Once this operation is completed in 1 to 6 weeks, you will be able to find out which offers are available on your line. We regret this situation and encourage you to come back and test the eligibility of your line in the next few weeks.

This could be really good news if France Telecom is actually moving our lines back to the exchange in our village. As I've mentioned in earlier posts, we have a France Telecom exchange roughly 500-600 meters from our house but it does not support residential ADSL. It's a small exchange and they've used it essentially to serve business customers. That means that all residential ADSL lines connect to exchanges in neighboring villages which are 4-5 km away - leaving us with very slow broadband.

Our previous mayor struck a deal with France Telecom where the village paid EUR 50,000 directly to France Telecom to upgrade the exchange so people could subscribe to "at least 8 Mbit/s". I thought it would take them a long time to pull off - and we will see. However, the fact that Neuf notified me that the work is in progress makes me think that we could have significantly faster DSL rather soon. This would allow us to finally take advantage of the TV over ADSL packages that many of us are already paying for in our triple-play packages.

Ramifications for the FTTH project:
I'll be the first to say that upgrading our exchange will be great for everyone in the village. At the same time, it may make it a bit difficult to convince people to shift to FTTH. It's a lot easier to sell when people have terrible connections but this just means we'll need to educate people a bit more about the benefits of open-access fiber. I'll still go ahead and put in the fiber in the residence. It may also be an opportune time to talk with the competitive operators before they being installing their own equipment (DSLAMs) in the upgraded exchange.

Slow broadband is becoming political in St Nom La Bretèche /L’Internet a haute vitesse devient plus important a St Nom La Bretèche

Happy new year.

I went out to my mailbox today and found a newsletter we receive in the village. It's called "La Parole est aux listes - Journal d'expression des groupes au Conseil Municipal de Saint-Nom-La-Bretèche". I always try to read through it and today I was happy to see some attention to the ADSL situations here in St Nom. In this issue the group "Saint Nom Tout Simplement" writes:

Suite à une demande pressante auprès du conseil municipal, Orange a obtenu l’accord d’implanter une antenne relais sur le terrain de football. Nous avions insiste pour qu’en échange et au préalable, la commune obtienne des engagements sur le déploiement de l’ADSL rapide dans la commune (3/4 des foyer sont aujourd’hui limites a 512 kbit/s). Malheureusement, cette facilite a été donnée sans obtenir de contrepartie pour l’accès a internet. Aussi, 4 mois plus tard, Orange revient très dominateur avec une proposition de couverture à 92% de la commune en ADSL rapide, moyennant une participation de la commune estimée a EUR 50k. Et c’est “maintenant ou jamais”. Le pouvoir de négociation a évidemment changé de coté. Quant on réalise que la seule alternative a l’internet 512k dans notre commune, c’est Noos/Numericable…, on comprend mieux l’attitude aujourd’hui intransigeante d’Orange. Dommage!

I'll try to give a quick and dirty translation into English.

Following a request in front of the Municipal Council, Orange received permission to install a relay antenna near the football field in the village. We had insisted that in exchange for permission the commune should have obtained promises that fast ADSL would be deployed in the community (3/4 of homes in St Nom are currently limited to 512 kbit/s). Sadly, the permission was granted without any accompanying promise for Internet access Also, 4 months later, Orange has come back in a very dominant position with a proposition to cover 92% of the village with fast ADSL as long as the village covers half of the cost of the upgrade estimated to be EUR 50,000. They say it is either "now or never". The negotiation power has clearly shifted to Orange. When we realize that the only other alternative to Internet access at 512 kbit/s in our village (it's Noos/Numericable), we can more easily understand Orange's intransigence.

I was happy to see that the broadband issue has been raised to all residences in St Nom through this handout. People do want better broadband. Noos/Numericable may say they are offering 100 Mbit/s but my connection has been off and on for the past 3 days and it will cost me EUR 15 to call them to report it. I'm using my backup ADSL connection for now.

I don't know what the mayor has decided about the EUR 50,000 but I hope he hasn't paid it. They will upgrade the exchange without the money, particularly if Numericable is sweetening their offer.

More importantly, there is another option. Our fiber-to-the-home plan is only for the 50 homes in our small area of the village but we could expand to other areas fairly quickly once we get a fiber line down to the local exchange. Just the fact that we're moving ahead with a fiber plan should hopefully spur Orange into upgrading their own offering here in St Nom.

I find it interesting that for not much more than EUR 50,000, the Mayor and the Municipal Council could run an open access fiber from the telecommunication exchange at the edge of the village all the way to the Mairie. From here different "residences" could tap in and access services from competitive operators over fiber. Orange should not have the bargaining power to demand village money to upgrade their own exchange. They just need some competition.

How long of a loop? / Quelle longueur pour la boucle locale?

It's clear to me that one of the most challenging elements for network operators is actually mapping out the most efficient topology in terms of capacity and cost. I thought I had decided how I would lay out the network but now I'm starting to wonder if I should readjust after certain developments here in France.

One of my big struggles now is how long to make the "local loop" element of the network. I know that "local loop" typically refers to a copper twisted pair but I'm not sure exactly what you would call its replacement in FTTH-speak.

Initially I had imagined putting a concentration point in the middle of our residence (100 meters away) where I could install active equipment. Then any operator could come and patch into us to offer services at the edge of our network. However, now I'm beginning to wonder if I should plan on taking all fibers all the way back down to the exchange 600 meters away.

If I thought that I would surely stop at just laying fiber in our residence then locating the active equipment next to us would probably be a good idea. However, the situation becomes a bit more complicated if I ever decide to spread out the fixed costs of connecting to exchange by expanding the project to other subdivisions at a later date.

I'm not sure that it makes good economic sense to place active equipment in each subdivision of a small village. It's not cost effective for the equipment and it surely introduces more potential points of failure. At the same time, it may not be cost effective to run a large amount of fiber to the edges of the village several kilometers away either.

Right now this is playing out in Paris. France Telecom's PON network requires less physical space than Iliad/Free's point-to-point network. That means that Free is likely looking for property all over Paris where it can locate active equipment to terminate its fiber closer to users.

I don't need to make all these decisions now since I can wait to see how the project progresses and if other subdivisions are interested in connecting with us. One of the important decisions for now though is how big of conduit I should put in leaving our residence out to the exchange? Do I plan for something big enough to accommodate future growth - even if it will increase my up-front fixed costs?

Meeting with Yvelines Numériques / RDV avec Yvelines Numériques

I met up with Jean LEBRET of Yvelines Numériques today in Paris. (For a quick reminder: Yvelines Numeriques is a public/private backhaul network running through our French department). We walked over to a small cafe to talk about the project when French fighter planes cruised right above us in formation - flanking what looked to be a bomber of some sort. It happened three times on the short walk and the jets even left blue and red trails behind them. The whole ground shook as they flew by. Very impressive. We assumed it was practice for Bastille Day coming up.

Yvelines Numériques network path

Once we sat down I explained what I wanted to accomplish with the project and where our residence is located. I may be wrong but I think he was a bit surprised with my determination to see this project through. He jumped right in too saying that he hadn't heard of a similar project yet in France and thought this could actually work in our favor - helping us convince politicians to help me out.

He pulled out his computer and we started going over the maps. It turns out we are very close to their fiber backbone network - but not quite as close as their public map had made it appear. Their network actually dips down a street lower from us, away from the main road, as it comes near the church (and near us). He was able to measure the distance from the edge of the residence to the nearest possible splice point for their network (310 meters). Still not too bad.

He gave me an estimate for how much it will cost to get from our network (in the residence) to his (closer to the exchange): EUR 120 per meter.

310 meters * EUR 120/meter = EUR 37,200

Expensive. He did mention that the prices for the dig could actually be lower (down to EUR 50 per meter) if we were mainly going through fields - which I don't think we would be.

I was a bit taken back with the costs of simply getting to the backhaul but it make me think of some other options, particularly wireless. I'll write about those a bit later.

The main thing I pulled out of our conversation was that he thinks the best way to approach this is by convincing the government to help us get connected to the network. We would essentially ask the village or department to pay for (or subsidize) the connection to Yvelines Numériques as a way for them to save money on connectivity for government offices in the town (e.g. schools, mayor's office, post office). The more he talked about it the more I thought this could be an option. He gave me the names of two people in the Conseil Général to contact who may be able to help. He also suggested I go back to the Mayor and try to convince him to pool the demand for the local government as a way to justify running a fiber between the mayor's office and their network. We could take some strands as the network passed by on the road to the commercial center.

France Telecom Exchange (St Nom)

This could be politically attractive option since the Department helped fund half the backbone network and they would have an interest in seeing it lit. Yvelines Numériques only provides the dark fiber so the more cables they can light, the better. I got the impression that the network has much more capacity now than is in use. Out of the 144 fibers in their first cable it sounded like less than 10% were lit in our area. They would definitely have room for us if we could get to them. He also explained that once we'd be in contact with their own fiber the costs would be quite low to go the rest of the way to the exchange (100 meters). They charge EUR 1.80 per meter per year.

Once we made it to the exchange other operators could easily supply us with services since they also have lit fibers on the same backhaul network. The operators may not have their own equipment in the exchange now but it wouldn't be difficult or expensive to simply create a drop point.

Finally, Jean recommended I use PEHD (high density polyethylene in English) for the conduit when I lay it down in the sidewalks. By his calculation I'd need around a kilometer of it and he said the costs wouldn't be too bad.

I was very glad that Yvelines Numériques got back to me and there may be a way to work with them on this. The costs seemed high but I feel at least that this was sign that I can actually make this work.

Should have said: "ensure unbundling"

You know, there was something I really wanted to mention to the mayor but forgot before I left. He mentioned that France Telecom wanted to upgrade the exchange. I should have told him that he should insert the requirement that in exchange for more land that they would need to build a space large enough to accommodate other operators and allow them to take unbundled local loops.

There's a good possibility that this would be required anyway by the ARCEP but I wanted to make sure that this exchange "upgrade" included the options for other operators to enter in and put in their own equipment.

DSL progress in St Nom? / Progrès de DSL à St Nom?

I rode the train home with two of my friends from the residence today (Patrick and Pascal). We talked about the project a bit and Patrick explained that France Telecom was working on building a large exchange (NRA) not too far from where we live, just across from the current (unused) exchange. The current exchange is very small (about the size of 2 refrigerators next to each other) and only serves business clients. However, he said that the new exchange is under construction just across the street from the current one and that it would be online in October. That would mean that our broadband options could increase dramatically around that time.

This is something I'd really like to speak with the Mayor about because it may have implications for the fiber project. Even if they did upgrade our DSL I think it would be crazy not to lay fiber down if we are re-doing the roads.

Patrick also explained that Noos, the cable company, has ducts in the street that maybe we could use. I figure it's probably going to be easier if we simply lay our own PVC pipe but it's something I'm going to look into. I was encouraged that both Patrick and Pascal seemed excited about the project.

Intro: The project / Intro: Le projet

I'm a telecommunications economist in Paris and I spend a lot of time thinking about and using broadband. We've chosen to live in a beautiful area of southwest Paris but one which has limited broadband options. In fact, broadband is terrible for everyone in our village. The incumbent operator (France Telecom) hasn't upgraded our own exchange for DSL and that means that people in the village are connected through one of two towns, each roughly 5 km away.

I subscribe to broadband via DSL and cable. At 4.5 km from the DSL exchange I receive 1 Mbit/s via the competitive operator Free - too slow for me to take advantage of their IPTV offer for example. I also subscribe to Noos for cable Internet. I pay for a 30 Mbit/s connection but receive only 3 Mbit/s - and even that is traffic shaped. Even 200 euros of calls to the helpline at 34 cents a minute hasn't solved the problem. I am not alone. It seems that almost everyone I speak with here has similar problems and people are getting fed up.

There is talk around town that France Telecom has offered to upgrade the exchange if the town will pay the costs (roughly EUR 50K). I say no. We're going to build this network ourselves. We are going to bring our own broadband to our homes.

Our goal is simple. We want a fiber to the home network capable of gigabit speeds which will be open to services from any operator. I've spent enough time writing about "open access" networks and infrastructure-based competition at work. Now it's time to get down and dirty and build one myself.

I've decided to keep a journal of my experiences along the way in case someone wants to replicate a similar rollout. This certainly won't be the first of it's kind. That honor probably goes to Måttgränd, Sweden. I'll be contacting them shortly for advice. However, I hope this project will show whether it is indeed possible for a small provider to roll out FTTH without economies of scale.
