This is an article that I have written for print publication. Any feedback would be appreciated.

2009 has been a strange year for carriers providing last mile DSL access. Back in January in the midst of the recession there were worrying times being forecast for carriers as they struggled to get to grips with the financial downturn. With networks struggling to plug widening deficits, previously planned network expansion was put to one side, as capital was shunted to other areas seen as more important to stopping the rot.

At the turn of the year, there were 4 main wholesale DSL carriers: BT Wholesale, Cable and Wireless, the Carphone Warehouse Group and Tiscali. Due to the recession, BT Wholesale were stalling with the roll out of 21CN, Cable and Wireless were just re-entering the channel after a strategic exit only a few years back, Tiscali were involved in a very public tug-of-war between Sky, Vodafone and the Carphone Warehouse Group whilst the latter themselves had only just entered the wholesale market via their wholly owned subsidiary Opal Telecom. As the year progressed and we started to move towards a brighter financial climate, the industry took a marked turn for the better. Many people debate about the exact period when we started to look more optimistically at the future. However I believe that when Brown put the ball in the court of the Telco’s by stating that the infrastructure behind Digital Britain would spur growth in the economy, there was a paradigm shift, as the masses adopted what we had already realised; that telecommunications was a fundamental component to the kick-start of the British economy.

Throughout the course of the year, the broadband landscape has changed considerably. The main difference being the acquisition of Tiscali into the Carphone Warehouse group and their subsequent ambitious plans for 2010. Whether they will demonstrate the traditional pains of large scale acquisition traditionally felt by other large carriers such as Tiscali and C&W is yet to be seen. BT Wholesale has also started to gain traction with 21CN and in particular their WMBC offering. Cable and Wireless can also pat themselves on the back as having a fairly successful year, as they managed to win the Tesco contract, whilst deploying their much heralded MSP platform. However one of the big changes to the market has been the introduction of BE into the wholesale arena.

BE have always had a very compelling consumer offering; being the first to market with Annex M ADSL2+, whilst having one of the largest coverage areas of the tier 1 DSL networks. With a topology designed to underpin high bandwidth usage, they were setup from the onset to provide ADSL2+ to their subscribers. BE have entered in a very timely fashion. One of the key topics of the year has been the increased financial burden of bandwidth costs on service providers due to applications such as iPlayer and Pirate Bay. This has led to in depth debates including key industry and government personnel about how best to manage the use of bandwidth intensive applications. Solutions such as bandwidth caps, application charges and even application restrictions were mooted. Due to their mesh dark fibre-based VPLS core, BE can legitimately claim to provide solutions future-scaled to support the continued rise in bandwidth by end users. Also with a commercial model that alleviates central based usage charges, they’ve provided a low cost-of-entry into the ADSL2+ market for channel partners.

As we move into 2010, the wholesale broadband market is much changed from that of 12months prior. Both Carphone Warehouse and 21CN have ambitious growth targets planned for 2010. The latter introducing wholesale Ethernet-in-the-first-mile and fibre-to-the-cabinet trials. Many people have stated that the window of opportunity for new wholesale partners is fast closing due to this. However in my position, the consolidation in the industry has reached a natural plateau, with all the main DSL carriers now proving to be more mature in systems interface, product portfolio and commercial model used. Even BE as the new player can be seen to have an edge in some aspects of their proposition. By using ISAMs (Intelligent Service Access Managers) at the exchange with the capability of terminating Ethernet and seamlessly training the DSL to work at its optimum performance (known as seamless rate adaption) they have made the step to solidify their position as a force in the market both now and for the future. By also providing unparalleled visibility and control of their ISAMs to all service providers, they have allowed tecchies to fault find, diagnose and alleviate traditional 3rd line issues, which in turn has led to a vast reduction in the number of support tickets raised with them.

Even though this has been in the market for roughly 6months, already the features are proving compelling, even as compliment to a 21CN novation plan. With products such as bonded DSL and symmetrical DSL soon to be available from the port, they’ve positioned themselves as a prominent player in the next generation access sphere. Add into the mix backhaul capacity capable of supporting their lofty ambitions and the capital of their more illustrious parents, it’s no wonder BE are proving to be more than just an interesting alternative in the wholesale broadband market.

Over at FD Wholesale, we’ve been doing some trials in our R&D department bonding Annex M tails together and we’ve been able to get throughput normally associated with leased lines. We’re roughly 1.5Km from our local exchange, and when bonding 2 lines, the total sync rate was 26.7Mbps down and 4Mbps up. When we bonded 4 lines, we obtained 56Mbps down and 8Mbps up.

The applications for this are wide ranging. Consider having a client who lives 5Km+ from their local exchange. 1 DSL would offer them little throughput to sustain a number of users. Aggregate 2 or 3 together and suddenly they can start to look at IP applications that may improve business processes such as SIP or Video conferencing. Another example may be where a client can’t gain wayleave agreement to obtain a fibre run. In this instance, they can have a bonded Annex M service offeirng up to 80Mbps down and 10Mbps up. Obviously these are headline speeds and are dependant on quality of copper and line length, but in all but the worst circumstances, a bonded Annex M service can start to become a compelling alternative to EFM or FTTC. Using the BE network, this is also available immediately, nationwide. No waiting for 2012 to have a coverage of c.300 exchanges.

Currently this is something that all our channel partners are utilising, as it gives them a cost effective alternative to a leased line. Based on the Cisco proprietory protocol, traditionally the stumbling point has been the high initial price point associated with the routers. However, we’ve been conducting some trials with a manufacturer called Virtual Access using their GW7000 boxes, and they’ve been very successful in terms of throughput and stability. However, even more compelling is the fact that they lower the initial price point of the solution to sub £500.

Personally I feel that bonding Annex M tails, at the core is a lot more resilinet solution than trying to aggregate them at the client end, using an external aggregator, as it means that there is little overhead, lower packet loss and less latency. In my opinion, the main thing to take away from this is that even though fibre will still have it’s uses, the applications for DSL are ever increasing. Whereby traditionally a leased line was the only method available to provide large amounts of throughput, the landscape is ever changing to incorporate DSL.

Converged Communication Solutions is the first independent Scottish Internet service provider (ISP) to offer a ADSL2+ broadband package, providing global energy businesses with increased bandwidth and faster Internet connection speeds. Benefits include increased efficiency for remote working (via remote access technology) as well as more effective communication via video conferencing technology.

            A recent report published by Oxford University Business School stated that UK broadband is not fit for use, ranking the UK’s systems 31 out of 66 countries. Britain was listed among countries whose broadband is only “meeting needs for today,” while technologically advanced countries like South Korea and Japan dominated, largely due to their commitment to super fast networks.

            Neil Christie, Converged technical director, said: “ADSL2+ will allow users to obtain more bandwidth for little or no extra outlay. Existing services (e-mail traffic, Web browsing, downloads and uploads) will be quicker, with newer services on the Internet, such as video streaming, becoming more accessible.

            “We are delighted to be the first independent Scottish internet provider to offer this broadband package. I believe it will enhance our clients’ productivity by offering greater speed and flexibility. Our aim has always been to provide a personal service that ensures our clients get the best solution for their communication needs.”

            The firm was recently recognized for its innovation in technology when it was named a finalist in the “Best Use of ICT” category at the Northern Star Business Awards.

Thought I’d include an article that I’ve recently written for the channel. It’s quite easy to read, but any feedback would be appreciated.

Thanks

Broadband has come a long way since it’s inception. For businesses back in the day, it was seen as a key marketing and communication tool as companies paid through the roof to have a static website with 5 pages. Email was revolutionary, and was quickly seen as the main way to communicate with clients, with their permission or without.

Now with the advent of converged or unified systems, it’s not surprising to have a company use their broadband for phone calls, data, video and even an alarm system. The advance of broadband has been the key driver in so many industries, each with their own confusing terms and acronyms. FMC, UC, SIP, Telepresence, VOIP, IPCCTV. The list goes on, but the common factor is IP – Internet Protocol. All the aforementioned use the internet.

On it’s own, its a cost effective method to transfer data, and because of it’s universal acceptance, is widespread across a number of mechanisms. Packaged with an IP application, broadband becomes fundamental for the efficient use of the respective device. For the channel, it provides a number of opportunities for vendors, distributors and system integrators alike to provide a necessary value add to their portfolio, and this is further pushed by the rise of alternative networks to use. This in itself has promoted competition and innovation in product development, and the channel has inevitably benefited from the options available. Now technologies such as Annex-M can help a reseller by going to market with an ISDN alternative, whilst also aggregating two or more to attack the leased line market.

At the top end of the channel, mobile operators have got into bed with Telco’s to have a network of their own. Large system integrators are courting network operators for a primary service. And at enterprise level, the wrath of mergers and acquisitions have left some in the enviable position of being a one stop shop for your every need, budget permitting. At the lower end, traditional resellers and SI’s have forged relationships with mobile and network operators to get the best out of both worlds. This is where the value has been added, as now an integrator has a platform to showcase their primary offering.

Lets look at one industry where this is rife, voice. Hosted voice providers who have been brave in embracing SIP have realised from a very early age that the quality of broadband is key to their offering. Therefore they have been vocal in their search for network operators who have an offering that can allow for a high quality and a high volume of calls.

Enter DSL. In it’s various guises, it’s been able to offer a low cost platform to end users wanting access to the benefits of a hosted voice offering, as now the high upfront costs of an ISDN 30 can be waived for a similar DSL service. In this instance integrators have been quick to partner with network operators to offer their services as part of a package, adding to their bottom line by boosting their margins and increasing that customer ’stickiness’ we all strive for.

The same is now happening in a number of industries. Integrators in the fast developing video sphere are reaching out to networks with a reputation for performance. Digital signage architects are holding hands with networks with good national coverage. And for the end user, this is compelling as they have one port of call for the majority of their IP requirements.

It’s an easy story to tell. To borrow a much used analogy, selling a road is pointless without drooling over the performance of the vehicle that’s on it. And to translate this to the internet, it’s hard to get excited about fibre to the home for example, without thinking about all it’s possible uses.

All these present the opportunity for more convergence, more applications, but over one central pipe, which is where the value is provided, as if you provide the central pipe, there is always the possibility to provide other services based on that. An old director of mine used to term this “The Whirlwind model”, where you provide something small, but essential, and then provide additional services required by that initial item. However you define it, the benefits of this are unparalled for all parts of the channel, as with the technological advances being made in the numerous access methods used to provide broadband, the channel now has a chance to offer a key value add to their IP applications.

Dear Sir of Super hyper broadband access,

I write to you after seeing your wanktastic commercial advertising your wankathon mega-hyper-power broadband of the 20 meg. I am well after your product. It looks like the shit.

Do you see? I am currently sitting on a wank-as-fuck (technical term) faulty broadband connection. In that wonderful commercial of yours – you know, the one with the MILF looking for houses and the Bristol Live Frogger fail chap relaying the house details to the hapless estate agent, who’s internets are slower than a phone exchange upgrade. Well, in that ad the connection the estate agent has is just like mine. It’s faulty as arse. Now I want me some 20 meg sexy broadband. Yes, I know my distance to the ‘exchange’ (where is that?) alters my speed, and if i’m miles away then it’s slower, but I just want me some working broadband. Just like in your tv advert.

So, i’ve decided to dump my fine and fair Internets Service Provider to go with you fuckers. I am sure upgrading me to your lovely-time-sexy broadband will fix all my wanky connection problems. My line will stop disconnecting, running slower than a concrete slab of shit and fuck up because your ad shows my “up-to-8-meg” connection and it’s toss. Then I see your “up-to-20-meg” connection and its awesome. I’m gonna be loving this. I cannot wait for extra-fast porn… soz, i mean learning shit from Wikipedia well fast.

Awesome.

Frankly, it’s tiring to see journos/bloggers piggybacking on consumer ignorance about how all things internet work. Sync speed is a variable based on many factors. The bitrate of a data transfer is completely subject to variables to do with the remote site as much as with anything else.

Achieving 24Mbps downstream with aDSL2+ technology is a marvel that doesn’t imply a ‘consumer’s right to achieve those speeds’. In Australia as I expect also in the UK, you wouldn’t get away with not using the disclaimer ‘actual speeds may vary depending on distance and other factors’.

Note how a more learned consumer comments “even a couple of metres can severely degrade the line due to interference from other wireless utilities in the house. (even that dreaded microwave!)”.

ISP help desks have to occasionally contend with customers who refuse to accept this yet still demand their ‘rights’. It cuts both ways.

It’s looking like a good business to run one of these sites and just criticize people doing all investment, technology and customer support. How does a survey by a glorified link farm become ‘research’ in the Times’ eyes?

Criticism is often justified but it’s clear that most consumers will never ‘get it’ as to how the net works and where there’s a buck to be made, there’s plenty of PageRank seekers who will exploit that.

Os principais serviços de Internet Banda Larga do país usam uma tecnologia denominada ADSL para transmissão do seu sinal abaixo segue algumas informações sobre esse serviço:

ADSL é a sigla para Assymmetric Digital Subscriber Line ou “Linha Digital Assimétrica para Assinante”. Trata-se de uma tecnologia que permite a transferência digital de dados em alta velocidade por meio de linhas telefônicas comuns.

Funcionamento do ADSL

O ADSL basicamente divide a linha telefônica em 3 canais virtuais, sendo um para voz, um para download e outro para upload. Essa divisão também é “física”, onde a separação desses canais é feita por divisão das faixas de frequências que são suportadas pelo cabo, devido as limitações do cabo e visando um melhor aproveitamento do cabo telefônico, a maior faixa de frequencia disponível ou seja o maior canal é usado para Download e o menor canal usado para Upload. Por isso os links ADSL são assimétricos com velocidade maior de Download e upload menor, abaixo segue um exemplo de como é feita essa divisão:

Divisão canais ADSL

Perceba que graças a essa divisão de canais é possível navegar na Internet e falar ao telefone ao mesmo tempo, para separar a voz dos dados é instalado na linha do usuário um aparelho chamado splitter, nele é conectado o cabo que vai para o aparelho telefônico e modem. Atualmente no Brasil o ADSL é usado em duas versões o ADSL e ADSL2+, na primeira versão usada geralmente para velocidades de até 2Mb os seus limites são de até 8MB para Donwload e 800kbps para Upload, no ADSL2+ o maior aproveitamento dos canais fez com que a velocidade de Download chegasse a 24Mb e upload à 1Mb.

O ADSL funciona usando um modem específico para esse tipo de conexão, como vimos acima na divisão de canais dentro da linha telefônica, ela é usada unicamente como um meio de comunicação entre o modem do usuário e a central telefônica, não é necessário pagar pulsos telefônicos, pois a conexão ocorre por intermédio do modem e não discando para um número específico, como é feito com o acesso à internet via conexão discada. Isso deixa claro que todo o funcionamento do ADSL não se refere à linha telefônica, pois esta é apenas um “caminho”, mas sim ao modem. Quando seu modem estabelece uma conexão com o modem da central telefônica, o sinal vai para um roteador, em seguida para o provedor e finalmente para a internet. É importante frisar que é possível que este sinal saia diretamente do roteador para a internet. No Brasil, o uso de provedor é obrigatório por regras da Anatel (Agência Nacional de Telecomunicações).

O sinal citado acima, depois de enviado à central telefônica, é separado e os dados vão para um equipamento DSLAN (Digital Subscriber Line Access Multiplexer), que limita a velocidade do usuário e uni varias linhas ADSL (é este equipamento que faz com você navegue à 256 Kbps mesmo quando sua conexão suporta 2 Mbps).

Todas as empresas que fornecem ADSL só o fazem se o local do usuário não estiver a mais de 5 Km da central telefônica. Quanto mais longe estiver, menos velocidade o usuário pode ter e a conexão pode sofrer instabilidades ocasionais. Isso se deve ao ruído (interferência) que ocorre entre um ponto e outro. Quanto maior essa distância, maior é a taxa de ruído. Para que haja uma conexão aceitável é utilizado o limite de 5 Km. Acima disso pode ser possível, mas inviável o uso de ADSL.

PPPoE

Diante das informações acima, você deve se perguntar porque em muitos casos é necessário usar um programa para se conectar à internet, se o ADSL permite uma conexão permanente usando unicamente o modem.

O ADSL por si só é um meio físico de conexão, que trabalha com os sinais elétricos que serão enviados e recebidos. Funcionando dessa forma, é necessário um protocolo para encapsular os dados de seu computador até a central telefônica. O protocolo mais utilizado para essa finalidade é o PPPoE (Point-to-Point over Ethernet RFC 2516).

O protocolo PPPoE trabalha com a tecnologia Ethernet, que é usada para ligar sua placa de rede ao modem, permitindo a autenticação para a conexão e aquisição de um endereço IP à máquina do usuário. É por isso que cada vez mais as empresas que oferecem ADSL usam programas ou o navegador de internet do usuário para que este se autentique. Autenticando, é mais fácil identificar o usuário conectado e controlar suas ações.

Você pode estar se perguntando: por que os primeiros serviços de ADSL do país davam IP fixo ao usuário, sem necessidade de usar o PPPoE, ou seja, porque o PPPoE não foi usado antes? Naquela época, o protocolo PPPoE era novo (foi homologado em 1999) e, conseqüentemente, pouco conhecido. Com isso, o usuário usava ADSL através de uma conexão direta do modem à central telefônica, sem necessidade de autenticar. Mas quando as empresas começaram a descobrir as vantagens do PPPoE passaram a implantá-lo. Isso permite à companhia ter mais controle sobre as ações do usuário.

Interesting news in the channel recently about how O2 have signed up with BT Wholesale to provide both fixed line data, broadband and consultancy services. On the surface this seems like a good opportunity for O2 to take a giant step into providing their client base with a converged solution based around their primary mobile offering. However one has to wonder why a comapny who has invested at the least £200 million on it’s own network would then make a further investment in providing a similar service based on another network.

The concept is sound. O2 have a massive mobile subscriber base, consisting of both consumers and businesses of all sizes. With their centre of excellences, they have one of the best support networks around for resellers of their products, to underpin their business offering. By offering their clients a unified solution consisting of business broadband seems like a sure fit. However, for one reason or another, this has never happened.

The acquisition of the Bethere network has enabled O2 to be a major player in the comms market. However so far, the market that has benefitted the most has been the residential market. This does not mean that the network cannot be used for businesses, just that so far, there have been few able to use it in this way. However with the advent of the wholesale channel, the network is now being used by business ISP’s as a primary offering to their client base, and is proving extremely successful in providing high bandwidth low latency services. As more exposure is given to this channel, it will be interesting to see how this is viewed by the powers that be in O2.

There’s nothing to say that a Be/O2 offering can’t co-exist with a BT service, as inevitably in the areas where Be don’t have an exchange unbundled, a rebadged BT service will be used. However, for my 2 pence, although BT Wholesale have persuaded O2 to sign a 5 year contract, I firmly believe that O2 will fully realise what an asset they have with the Be network, before we get anywhere near to the expiry date of their new contract with BT.

Warning: this post contains a large number of acronyms!

Interesting news this morning about how Openreach is reacting to the recent Digital Britian report in providing universal 2Mb broadband services. Using a method called Broadband Enabling Technology, or BET for short (yet another new acronym), Openreach proposes to provide a stable broadband service at distances of up to 12Km from a client’s nearest exchange. For premises situated within a current ‘not spot’ (thank the BBC for that term!) this could prove a viable alternative to using a mobile network or satellite operator, as having a fixed line broadband service would prove a lot more consistent, and also would not be as susceptible to enviromental conditions.

At first glance, it seems that BT have taken the idea of SDH and applied it to longer distances. Looking at the way this is depoyed, it seems that BT Openreach is extending the reach of it’s SHDSL services past the previous 5Km barrier. Currently there is little technical information about how they will do this, bar stating that they have made some “modifications and the use of a repeater unit”. However, it’s interesting that they’re using what was previously thought to be an end of life product, superseeded by both EFM and Annex-M, to provide services to the out of reach.

Since the Digital Britain report, there has been a lot of talk about how to provide a nationwide service capable of providing a universal 2Mb for a number of applications such as BBC’s iPlayer, VOIP and VOD to name but a few. Many different access methods, such as HSPA, WiMax and even satellite links have been considered in rural areas not deemed capable of obtaining a traditional fixed line ADSL service. In their various guises, they have provided a large amount of competition to fixed line operators whose coverage does not extend to ‘not spot’ areas. However these efforts have been largely independant to each other, and despite the advancements in technology within the fixed line communications sector, there hasn’t been a lot of options for people out of reach of their exchange. HSPA has proved not consistent enough, with users depending on mobile network coverage. With recent news of the Orange and T-Mobile merger, this could be something that may improve moving forward. Satellite broadband still does not have a large enough market penetration rate to be considered as a viable nationwide alternative. And WiMax is often used in backhauling bandwidth to out of reach areas, as opposed to a last mile access method.

By BT bringing this product into it’s portfolio it will go someway into giving it’s wholesale partners options to provide their ‘out of reach’ client base with a solid service for extensive use. With speeds of 1Mbps both down and up on a single copper pair, this is a positive step by BT in the right direction.

However, this also raises a lot of questions. All the marketing info we’ve been fed with relating to 21CN has previously made us aware that providing ADSL2+ from all of their exchanges was something BT were looking at having in place by 2012. It will be interesting to find out whether (should initial trials be successful) this may impact the rollout of Bt’s 21CN network. Also it will be interesting to find out the costs to the end user for this, as if it is using SHDSL technology, I couldn’t imagine the price point being markedly different to that previously. BT Openreach have admitted as much by stating “If there is funding to help meet the additional costs involved in deploying the technology, BET could offer a reliable and cost-effective solution to assist the Government’s ambition of delivering a minimum 2Mb/s service to virtually all UK homes”. Also, apart from throwing more copper pairs into the mix, it’s not really a scaleable solution for future bandwidth use.

All in all, it’s nice to see BT finally providing something that seems born out of market pressure. As mentioned, trials are being conducted currently. It will be even more interesting to see whether this proves both a commercial and technically sound option moving forward.

12 months after signing up for ADSL2, I have finally got ADSL2!  Yep it’s taken that long!  No, not iiNet’s fault – but it seems that my local exchange actually didn’t have enough physical space to add more lines – so I was basically waiting for someone to leave or Telstra to renovate the exchange.

But when it was all switched over, my speed increased from about 1Mbps to just below 2Mbps.  What was going on?

I knew I had phone line issues.  Whenever people call us on the land line, it would cut out the internet.  That definitely points to a filter problem.  But I thought we had a central splitter installed.

After some reading on Whirlpool, I got a professional communications installer in and we found that there was an internal wiring problem – my ADSL modem line and phone line were both filtered!

So he fixed that and suddenly I’m getting 5.5Mbps. Much better than before, but still less than the theoretical maximum of 24Mbps – but enough to stream videos and use the PlayStation Network with less delays.  And no more cutouts when someone calls us!

The proposed optical fibre network should help in the future, right?

Note to self – in the future, don’t let the installer go until you check you have a good data speed and it doesn’t cut out when people call in!

Telstra slugs new landline customers with $100 penalty for moving to naked DSL

I’ve been observing people’s ire at having to go through this signup-and-cancel process with Telstra in order to get Naked DSL with their provider of choice.

It’s tempting to be overly relativistic and try to look at Telstra’s view as there is ‘work’ involved in provisioning a new line, however, we’re talking about a company that has milked it’s monopoly for hundreds of billions of dollars for as long as we can remember and which has simultaneously stymied growth of and affordability of real broadband in Australia.

I have no sympathy for them. The government should force them to provide provisioning promptly and at a fair price and if they don’t like it, they should embrace the opportunity they will one day have for operational separation at which time the curse that they have been to consumers and competitors alike will be ended.

Per accedere la configurazione del router dovete connettervi all’indirizzo: http://192.168.1.1/main.html Nome utente: admin Password: admin Consiglio di eliminare le impostazioni sulla scheda di rete (vedi punto 3 di questa guida) e lasciare “ottieni automaticamente indirizzo IP” e lo stesso per i DNS.

Ed ecco finalmente l’accesso a tutte le funzioni del router! Se non siete pratici con la configurazione del router partendo da zero allora vi consiglio di caricare la nostra configurazione funzionante! e fare solo le piccole modifiche del caso

VDSL , ADSL2 çıktı çıkacak derken bugünlerde Telekom karşımıza çok sevindirici bir tarife ile çıkıverdi. Kısaca değinmek gerekirse şuana kadar ADSL kullanıcıları için maksimum internet hızı 4096 mbit idi, ancak bu yeni tarife ile bunu bir adım daha öteye götürüp bağlantı hızınızı 8192 mbit hızına çıkartabilirsiniz.

Resmi sayfasında yer alan ücretlendirme tablosunda da görebileceğimiz üzere fiyatı 99 TL olarak belirlenmiş. Hatırlayacağınız üzere en son %5′lik vergi indirimi sebebiyle bağlantı ücretlerinde kısmi bir düşüş yaşanmış, bu yeni tarifeye en yakın bağlantı hızının (4mbps) aylık ücreti 82 TL’ye çekilmişti. Yani 4 mbps ile 8 mbps arasında sadece 17 TL’lik bir fark var.

Bu bağlantı hızıyla 100 mb’lık bir dosyayı yaklaşık 2dk’da indirmek mümkün. Youtube ve benzeri video paylaşım sitelerinde yer alan HD kalitesindeki videoları ağız tadıyla izlemek nasip işi olmaktan çıkacak.

100 mblık lost dosyası indirilirken..

Bu bağlantı hızına şimdilik her ADSL kullanıcısı Türkiye’nin neresinde olduğu fark etmeksizin geçiş yapabilir. Yapılması gereken tek şey bağlantı sahibinin müşteri hizmetleri numarasını yani 444 0 375 i arayıp, yeni tarifeye terfi ettiğini belirtmesi.

İyi uçuşlar efendim.

سلام دوستان.

اومدم چندتا نکته رو به عرضتون برسونم.
1) اول یه سوال:
من الان ADSL دارم از داتک. 128 هست. میخوام 256 چندکاربره بگیرم. حالا برای منطقه ی ما، دوتا انتخاب هست: داتک و شاتل.
سوالم اینه که کدوم بهتره؟ و سوال مهمتر:
داتک ADSL میده و شاتل، ADSL2+، کدوم یک از این خدمات بهتره؟

Σημαντικά βελτιωμένη αναμένεται να είναι η εμπειρία που θα έχουν οι Έλληνες χρήστες του Internet όταν επισκέπτονται ιστοσελίδες που φιλοξενούν οι εγχώριοι πάροχοι μόλις ξεκινήσει τη λειτουργία του το GRIX (GReek Internet Exchange). Tο GRIX είναι ο νέος κόμβος διασύνδεσης των Eλλήνων παρόχων υπηρεσιών πρόσβασης στο Διαδίκτυο, ο οποίο λειτουργεί ήδη πιλοτικά, ενώ εντός των επόμενων εβδομάδων αναμένεται να ξεκινήσει και η κανονική λειτουργία του.

«Πρόκειται για ένα ουσιαστικό βήμα για τον εκσυγχρονισμό των υποδομών του ελληνικού Internet» επισημαίνει ο Παναγιώτης Tσανάκας, πρόεδρος του Eθνικού Δικτύου Έρευνας και Tεχνολογίας (EΔET), του φορέα που έχει αναλάβει τη διαχείριση του συγκεκριμένου κόμβου. Tο GRIX φιλοξενείται στις εγκαταστάσεις του Eθνικού Iδρύματος Eρευνών στο κέντρο της Aθήνας και ουσιαστικά αποτελεί το διάδοχο του υπάρχοντος κόμβου, του Athens Internet Exchange (AIX).

H σημασία του κόμβου διασύνδεσης, καθώς έχει ως αποτέλεσμα η τηλεπικοινωνιακή κίνηση από έναν πάροχο που καταλήγει σε άλλον εγχώριο πάροχο να μην χρειάζεται να πάει στο εξωτερικό και να επιστρέψει. Oυσιαστικά, η ύπαρξη του κόμβου διασύνδεσης μειώνει τον χρόνο που απαιτείται για να εμφανιστεί μία ελληνική ιστοσελίδα στην οθόνη του χρήστη.

Σε σχέση με το AIX, το GRIX θα είναι σε θέση να προσφέρει καλύτερες ταχύτητες, δεδομένου ότι οι πάροχοι θα συνδέονται με κυκλώματα της τάξεως τουλάχιστον των 10 Gbps ο καθένας.

Aυτή τη στιγμή, η συνολική κίνηση που εξυπηρετεί το AIX είναι στα επίπεδα των 10 Gbps. Eπίσης, οι υψηλότερες ταχύτητες θα βελτιώσουν την εμπειρία των Eλλήνων χρηστών όσον αφορά στην πρόσβαση σε νέες υπηρεσίες και εφαρμογές που έχουν μεγάλες απαιτήσεις.

Aκόμη, το κόστος για τους παρόχους θα είναι αρκετά χαμηλότερο, δεδομένου ότι θα φθάνουν στο GRIX με δικές τους υποδομές, ενώ το ενοίκιο είναι εξαιρετικά προσιτό.

GRIX: Σύνδεση όλων των παρόχων

Στο GRIX έχουν ήδη αρχίσει να διασυνδέονται οι Έλληνες πάροχοι. Mέχρι στιγμής, Forthnet, HOL, On Telecoms, Tellas και Vodafone έχουν αρχίσει τις προετοιμασίες για την διασύνδεσή τους, ενώ και ο OTE έχει συμφωνήσει για να συνδεθεί και μένει να επιλυθούν ορισμένα τεχνικά ζητήματα για να ξεκινήσει και αυτός τη διαδικασία διασύνδεσης. Eπίσης, και η Cyta συζητά το ενδεχόμενο διασύνδεσης στο GRIX, το οποίο, σημειωτέον, ότι θα μπορούσε να λειτουργήσει ως κόμβος διασύνδεσης όχι μόνο για την Eλλάδα αλλά και για την ευρύτερη περιοχή.

Nombreux sont ceux qui cherche a mettre toutes les chances de leur cotés pour pouvoir naviguer tranquillement via le Haut Débit que ca soit ici ou chez France Telecom les conditions sont les mémes .
Comme vous le savez notre réseau téléphonique est un peu ancien ,dans le jargon on dit un réseau filaire Hétérogéne (diametre du câble non homogéne 4/10,6/10,8/10).
de mon coté j’attaque autre chose sans parler de fournisseur d’accés malgré que tout fournisseur doit lui même assurez la meilleure topologie de son réseau pour de meilleurs résultats).

 
Si vos prises ont l’air fatigué (lamelles de contact ternes, etc.), vous pouvez en acheter dans une grande surface de bricolage et les changer, ça ne peut qu’aider.

Enfin, dernière chose à contrôler, branchez votre modem tout seul sur une prise sans aucun autre appareil branché sur la ligne. Pensez également à tester d’autres filtres, au cas où.

Ca c’est pour le côté purement câblage (les malades voudront sans doute changer tous les câbles du poteau à la prise).

Après, vous avez les problèmes venus de sources purement magnétiques.

Les parasites:

Au rayon champ magnétique, on peut voir :
 

• Les lampes halogènes (et tout autre appareil tirant pas mal de jus) branchées sur le même disjoncteur que le PC et/ou le modem (si il a une alimentation externe). Rien à voir avec le problème du bus USB qui ne supporte pas plus de 500mA, il s’agit ici d’appareils tirant vraiment beaucoup de jus (chauffe-eau, four électrique,…) à proximité directe du câble de la ligne de téléphone (1 ou 2 mètres).
• Les portails automatisés, avec souvent le câblage passant dans le même fourreau que celui de la ligne téléphonique.
• Vérifiez qu’il n’y a pas d’alarme connectée à la ligne téléphonique.
• Mauvaise aération du modem.  si vous trouvez que c’est chaud, c’est-à-dire non supportable au contact de la peau de votre poignet (côté paume de la main, comme une maman teste la température d’un biberon), c’est pas bon. Au besoin, ne serait-ce que pour tester, procurez vous un ventilateur et aérez votre modem voir si ça arrange les choses.

Les parasites : Quelques remèdes

Dans un premier temps, assurez-vous d’avoir mis un filtre sur chaque prise téléphonique :
Dans 90% des cas, la friture sur la ligne vient du fait que certaines prises ne sont pas filtrées (en général des prises vides).

Ensuite, si vous avez une rallonge téléphonique entre le modem et la prise, il faut tester sans la rallonge.

Puis, inter-changez les filtres, il y en a peut-être une défectueuse.

Adaptez des “Tore de ferrite” (photo) avec fermeture type MSFC (Boîtier en matière plastique, avec fermeture ) :

Ces tores permettent la protection des câbles de transfert de données et des divers appareils électroniques contre les parasitages extérieurs .  A chaque extrémité de votre câble allant de votre prise téléphonique à votre modem, faites une boucle sur la Tore de ferrite puis clipsez-la.

Vous pouvez aussi utiliser une ferrite récupérée dans une vieille alimentation de PC (comme un anneau). Faite deux à trois tours dans l’anneau de ferrite. Scotchez, terminé.

Pour revenir au diamétre des fils a Savoir .

Diamètre    Atténuation
4/10 mm : 15 dB / km
6/10 mm : 10,9 dB / km           
8/10 mm : 7,9 dB / km

Par exemple, si une ligne de 2500 m n’est composée que d’un tronçon en 4/10 mm,
son atténuation sera de :

2.5 * 15 = 37.5 dB arrondi à 37 dB

Si la ligne fait toujours 2500 m mais qu’elle est composée d’un tronçon de
1000 m en 4/10 et de 1500 m en 6/10 mm, on aura :

(1 * 15) + (1.5 * 10.9) = 31.35 dB arrondi à 31 dB

Si la ligne de 2500 m est composée de 400 m en 4/10 et de 2100m en 8/10 mm :

(0.4 * 15) + (2.1 * 7.9) = 22.59 dB arrondi à 23 dB

C’est ce qui explique que pour une même longueur de ligne on obtienne
des valeurs d’atténuation très différentes d’une ligne téléphonique à une autre.

Votre avis m’interresse..

It seems like we have entered the grubby season of the exhibition. I say grubby as some of the exhibitions I’ve been to previously have consisted of nothing more than a myriad of stands of vendors who don’t understand what you do, trying to sell you something that you inevitably don’t really need.

With the recent ‘Margin in Voice and Data expo’, there seemed to be a distinct change in direction towards a more focused show. I personally saw it as a good time for event organisers to re-evaluate their expos. However with the economy showing signs of picking up, there has been a return to the scene of the big all encompassing show stopping exhibition. Last week I went to the IP expo. Usually filled with big stands with big companies with even bigger egos. However this year was different. I only went for a morning on the first day, but what I found was an exhibition with a clear theme; Virtualisation. Previously where there were 4 expos centered around different aspects of cloud computing. This had now been amalgamated into one big show. Personally it was interesting to have a chat with different network operators, followed by walking across the room to discuss compatibility issues with specific vendors and system application developers. I found this a lot more worthwhile and was able to get a good level of understanding as to how different vendors/suppliers plan to incorporate a cloud based service into their product portfolios.

I then recently went to the ‘Convergence Summit South‘ run by Miles Publishing. This is specific to the channel within the telecomms industry and by their own admission has been their most successful summit for a while. As exhibitions go, it was exactly as expected. However the shining light of the expo was the seminars. Personally there was a great debate early on between Tim Hubbard of BT Wholesale, Neil McArthur of Talk Talk and Steve Gallagher of Cable and Wireless about what constitutes a ‘Next Generation Network’, and how their respective organisations are striving to compete. In my view, the term NGN is extremely mis-leading and one used purely for marketing spin. To see these industry heavyweights vying with each other about their own USP’s, whilst surveying the potential future landscape of the telecomms market was exciting, as little more than 5 years ago, BT would not have had to defend against such strong competition. The expo also saw an interesting feature, whereby hosted VOIP providers were given 20 minutes to setup from scratch their hosted platform in front of a packed audience. The one that I saw was successful and proved the ease of use and speed of the platform.

In all, expo’s can provide a valuable insight into your chosen market. Going back to the convergence summit, it was interesting to see how many big mobile carriers were present, as they tried to embrace the shift to FMC by traditional voice and data integrators. It’s a shame that the example set by the ‘Margin in Voice and Data’ expo earlier in the year was not followed, and I’m sure that as we emerge from the recession, various exhibitions will only continue to get bigger and probably more brash.
