Home Gateway Unit is Movistar’s new router with integrated ONT and videobridge

This new Home Gateway Unit router not only has the integrated ONT so that we only have to have one device turned on, but it also offers the videobridge feature to play Movistar TV. The main characteristics of this new router is that it has four Gigabit Ethernet ports for the LAN, one FXS VoIP port to be able to call by phone, and the most remarkable of all: its wireless connection.

The Home Gateway Unit incorporates Simultaneous dual band with AC Wi-Fi, we can get a speed up to 300Mbps on the 2.4GHz band thanks to its two internal antennas in MIMO 2T2R configuration. Regarding the 5GHz band we can get a speed up to 1,700Mbps thanks to its four internal antennas in MIMO 4T4R configuration and Wi-Fi AC technology.

The main CPU of this equipment is the Broadcom BCM68380 with support for up to 1 Gbps symmetric via FTTH, with respect to the Wi-Fi AC chipset is the Quantenna QD840s, leaving Broadcom chipsets aside.

In addition to incorporating a WPS button for each frequency band, it also incorporates a QR code on its front so that connecting mobile devices such as smartphones and tablets is really simple.

Movistar with this movement wants to provide its customers with a high-performance router so that it is not necessary to acquire another model of generalist brands, in fact by incorporating the integrated ONT it has hit a hard stick to these brands since it surely cannot be configured in mode “Bridge” so that the router you connect behind it works as a router, and not as a switch + AP. Besides that if it could be configured in «bridge», we will surely lose the VoIP.

They manage to transmit data at a speed of 57 Gbps by optical fiber

While copper cannot give much more of itself, fiber optics is a relatively new technology that can still be used much more. While currently the most widely used fiber speeds in Spain are 300Mbps (up to 1Gbps sometimes), researchers are studying different ways to make the most of this technology. Until now, the fiber optic speed record was at 40Gbps, however, this record has been broken by a group of researchers thanks to the oxide-VCSEL (Vertical-Cavity Surface-Emitting Laser) technology.

Recently, a group of three researchers from the University of Illinois has achieved a new milestone in data transmission over fiber optics. These researchers have been able to transmit data without errors in a normal environment (a room without special temperatures if extreme cooling systems) through fiber optic cables to a speed of 57 Gpbs.

Thanks to this new study, researchers have achieved reduce the temperature of fiber cables when transmitting data at more than 50Gbps up to 85ºC, thus addressing one of the main problems that telephone operators face when trying to increase the bandwidth of their connections and allowing, for example, data centers no longer have to depend on cooling systems additional to provide those speeds.

This new fiber optic transmission speed is designed to decongest 4K and VR content networks

One of the problems that ISPs are currently facing is with network congestion due to new technologies such as the transmission of 4K video (via platforms such as Netflix) and the virtual reality (VR) streaming, forcing companies to make expensive investments to support this traffic load.

Being able to transmit data at this speed without sacrificing the temperature of the cables allows, in the first place, a greater bandwidth for this type of content, which will be retransmitted in a much more fluid and without congestion and second, data transmission at an acceptable temperature, which reduces errors generated during transmission and allows companies to reduce the costs of infrastructure and cooling systems.

Undoubtedly an important milestone in terms of data speed that, although we will not see such speeds in domestic environments, we can indirectly benefit from them by obtaining faster and, above all, decongested connections so that traffic arrives point to point with the least number of obstacles possible.

What do you think of this new speed record?

DIGI mobil uses CG-NAT in its optical fiber and does not allow to open ports

Digi Mobil provides a router that does not allow to open ports (Port Forwarding)

In order to host services in your home such as an FTP server, a web server, or use private cloud storage services such as Nextcloud, you need «open ports»On the router, since we currently use NAT (Network Address Translation) so that all users in our home jump to the same public IP address.

The router provided by the Digi Mobil operator is so limited in functionalities that it does not even allow a “Port Forwarding” to be carried out, so if you have a NAS server you will not be able to access it remotely, you will not be able to host it at home a VPN server, and it is even very likely that you will have problems if you play online.

This detail that the router does not allow to open ports, could be avoided if we decide to buy our own router and replace the one from the Digi Mobil operator. But currently the operator does not provide the PPPoE connection data to allow this.

Digi Mobil also uses CG-NAT, your public IP is shared with more clients

As if not being able to open ports on the router were not enough, if you decide to change the operator’s router and have obtained the connection data, you will not be able to use a large number of services in your home, because the operator uses CG-NAT. CG-NAT is a technology that allows an operator to share the same public IP with several clients, usually up to 32 clients for each public IP address.

Different users have contacted RedesZone through Twitter to inform all customers about this matter. We hope that Digi will listen to you very soon and allow everyone who requests it to be removed from CG-NAT, as well as allow ports to be opened on the router.

Another operator that uses CG-NAT is Masmóvil, Yoigo and Pepephone, but this operator has been able to listen to users, and allows “to leave” the CG-NAT simply by notifying the technical service. In this way, Masmóvil provides a unique public IP to each user who requests it, although by default it is enabled in both its fiber and ADSL network. Another important aspect is that the routers provided by the Masmóvil group do allow to open ports without problems, unlike the Digi router.

Do you suspect that your operator has put you in CG-NAT? We recommend reading this:

Another claim of Digi users is that the customer service listen to them to get them out of the CG-NAT and allow ports to be opened.

Is it so important not to be able to open ports or to be in CG-NAT?

In RedesZone we were one day with CG-NAT of the Pepephone operator, and with the same use that we normally do with our Jazztel fiber with public IP, we saw big differences, and that is that basically we will not be able to use any internal service on your local network. We recommend reading it in case you contract with Digi Mobil everything that you will not be able to do:

We hope that Digi Mobil will allow users to open ports and get the most out of their fiber connection very soon. We leave you an article where we explain what differences are between FTTP and FTTC.

Meet Movistar’s new ONT for your FTTH

In this case we are going to talk about an ONT and not a fiber router that usually arouses more interest and comments. One ONT (Optical Network Termination or optical termination point) transforms the optical signal into electrical impulses so that digital devices can understand it, that is, it transforms the optical fiber into Ethernet output. Normally the ONT is connected to the router to provide Internet connectivity since it has an Ethernet output, in this device the telephones that we will use in our home can also be directly connected with RJ-11 connectors if they have them.

The team we are going to talk about is the latest ONT that Movistar is distributing, specifically it is the model Edge Core GG-11000 that you can see here:

The characteristics for which it stands out is that it is significantly smaller than the ONTs that were mounting to date since it fits in the palm of one hand. In my house they put the Alcatel Lucent I240G-T and this device occupies practically the same space as a former adsl router such as a Zyxel Prestige 660hw-d1 or a Comtrend 536+. So that you can see the ports and buttons of the ONT Edge Core GG-11000 you have the following photo:

ont_edge_core_gg11000_movistar_2

At first glance, everything seems correct and you would not put any hits on it, especially if it is the first ONT they put on you. However, if we compare it with the Alcatel Lucent I240G-T we see that it does not have RJ11 connectors to directly connect our phones.

This implies that since the ONT Edge Core GG-11000 does not have RJ11, you will have to use the ones that come in the fiber router and in the future it may limit you in the following way:

  1. The day you unsubscribe you have a deadline to return the router, in case you don’t know, they are free on a rental basis. You do not have to pay anything but you do have the obligation to return it within fifteen calendar days following the termination of the contract. Therefore you would not have a telephone, or you would be forced to buy a device to replace it or pay the penalty.
  2. If you turn off the router you run out of phone, you could no longer do it and save a little light.
  3. If you want to replace the Movistar fiber router, you would be obliged to buy models with support to put telephones through RJ11 or make a more complex combination with the new Movistar ONT + Router + Router.

These last two can be relative since there are people who like to have the router on all day and not everyone changes the fiber routers that Movistar uses. Personally, I am more convinced by the Alcatel model, however for space reasons others will value the Edge Core ONT more.

And which of the models would you like to be installed?

Jazztel makes it difficult for its FTTH customers to change the router for their own

However, the weak point of these ultra-fast connections is in the equipment provided by the operators, in this case Jazztel. Previously it provided the necessary ONT to connect with the OLT (central) and additionally a neutral router with support for telephones. Replacing the Jazztel router was very simple since we only had to assign a specific VLAN in our new neutral router and we would already have Internet, later if we wanted to also have telephones, we could place the Jazztel router so that it only managed the VoIP with the telephones connected to he. Jazztel did it really well, it provided symmetrical speeds of 200 Mbps and it also had equipment that gave the user freedom to change it whenever they wanted and in this way extract the maximum performance from the connection.

However, Jazztel has launched new router models with integrated ONT, and they do not have the possibility of configuring it in bridge mode so that they only act as ONT. One of the models with built-in ONT that is being distributed is the ZTE F660, and does not allow bridge mode, in fact in the ADSLZone forums We found many complaints from users asking Jazztel to place their old equipment in them because that way they could use their own router. Another all-in-one model is the ZTE F680 with AC Wi-Fi and better technical features than the previous one, but it is not being provided to customers in bulk yet.

We must be very critical of Jazztel’s policy: provide an all-in-one router without the possibility of configuring it in bridge mode so that an external router establishes the connection to the Internet and provides the maximum possible performance. Because one of the problems of these routers that the operator offers is in the Wi-Fi connection, in the forums you can read a large number of complaints about this problem.

Some users with the ZTE F660 are asking Jazztel to provide them with the old equipment, so that they can place their own router. However, we ask ourselves a question: How long will Jazztel have this old equipment in stock for new customers?

We want to know your opinion: Do you prefer that Jazztel put an all-in-one without the freedom to put your own router or rather than give the user freedom to choose the best for their Internet connection?

We recommend you read the analysis of the ZTE ZXHN F680 Wi-Fi router from Jazztel.

Pepephone will launch fiber optics with MasMóvil and Orange coverage in February

Since it was bought by MasMóvil, the operator Pepephone has undergone important changes, recently they presented new mobile rates and also new convergent mobile and ADSL2 + packs. The highlight of their new mobile rates is the free increase in gigabytes of data in various rates, and they even launched a 10GB data rate for only 24.90 euros. In the following article you have all the details:

A very important detail is that we will soon improve the ADSLZone Pulpo Pepe rate, this rate is currently available to contract with data and also without data.

Pepephone moves to the MasMóvil and Orange network in ADSL2 +

A few weeks ago we told you that the operator Pepephone will begin to register new ADSL2 + under the MasMóvil and Orange coverage, so they will no longer use the Vodafone network to provide their customers with Internet access. In addition, for the month of April it is expected that all clients will switch from the Vodafone network to the MásMóvil and Orange networks, in this way, all Pepephone clients will be under the same ADSL2 + network. This migration will be as transparent as possible for customers, although it will be necessary to reconfigure the router to adapt to the MasMóvil and Orange network settings.

Pepephone’s fiber optics: In February we will see the entire commercial offer

As our colleagues from ADSLZone have learned, Pepephone’s offer will be symmetrical, this means that we will have the same download speed as upload speed, in addition, the monthly fee that will have to be paid will be around 30 euros (line fee and VAT included) so it will be one of the cheapest on the market, as is currently the case with your Pepephone ADSL.

Unlike the rest of the operators, In Pepephone you will have to pay a registration fee to support the equipment costs (ONT and router), in the case of ADSL2 + the exact same thing happened, since Pepephone directly sells a router preconfigured with its ADSL2 +. However, it is very likely that Pepephone allows users to configure their own equipment or their own devices, in this way, we will not have to pay the registration fee.

Reusing the FTTH routers of other operators: a complicated and even impossible task

ISPs normally provide routers to their customers with very limited advanced configuration options, in fact, in some cases it is impossible to modify the WAN profiles of the router itself. In the case of ADSL2 + at a general level, it has been possible to achieve in most cases, especially in the old routers that the operators provided years ago.

However, the FTTH routers currently provided by ISPs are much more limited, especially when it comes to configuring the GPON and the WAN. Routers such as Movistar’s HGU do not allow modifying these advanced configurations, nor do the popular Orange Liveboxes, however, a model that could be configured with a different operator is ZTE F680 of Jazztel, although it is no longer marketed.

Buying ONT and your own router will be a feasible option

Although we still do not know the technical details that the teams will need, considering that they all follow the GPON standard, we will be able to buy this ONT from the manufacturer TP-Link to connect to the operator’s OLT, the price of this equipment in Landashop It is about 35 euros.

TX-6610

Next we will have to buy a router, we do not know if they will use VLANs or not in their Internet service, but currently the main routers do incorporate the 802.1Q standard so you will not have problems:

Manufacturers such as ASUS, TP-Link or Netgear incorporate a complete firmware to configure VLANs, in addition, if you have other routers such as D-Link with DD-WRT firmware, you can also configure it without problems.

Convergence with mobile rates and fiber optics at Pepephone?

Initially, the operator will bet on offers a fiber optic connection to the home without a telephone, but it is obvious that the next step will be to launch convergent mobile and fiber optic rates.

We recommend access our comparison of fiber optic offers.

The TP-LINK TX-6610 is the first ONT with GPON technology from the manufacturer, ideal for your FTTH

Technical characteristics of the ONT TP-LINK TX-6610

The main characteristics of this ONT TP-LINK TX-6610 is that it is specifically designed for current FTTH connections that use the GPON standard and incorporates one SC / APC port to insert the fiber optic cable. It also has one Gigabit Ethernet port (10/100/1000) to connect this ONT to a router that will establish the Internet connection. This equipment has two physical buttons, one for on and off the equipment itself, and another RESET button.

This ONT supports the GPON ITU-T G.984.1, G.984.2, G.984.3, G.984.4 standards, the optical module is class C +, the receiver is APD-TIA and the transmitter is DFB Laser, it supports a length of 1490nm data download wavelength and 1310nm data upload wavelength. Regarding the speed that it is capable of supporting, they are those of the current GPON standard, 2.48Gbps download and 1.25Gbps upload, but this speed will be limited by the outgoing Gigabit Ethernet interface.

TP-LINK TX-6610 Firmware Features

The main characteristics of its firmware is that it supports the 802.1Q standard for operators that use VLANs in their fiber optic connections. It can be configured in transparent mode, access mode and also in trunk mode, in addition the authentication is based on SN and password, so we must extract this information from the ONT of our current operator to be able to authenticate to the operator’s OLT.

Other features of the firmware is that it supports AES encryption for communications with the OLT, packet filtering, VLAN-based quality of service and also incorporates bandwidth limiter as well as support for IGMP, IGMP Snooping and IGMP Proxy. Regarding the administration of the ONT, we can do it through a graphical interface, in fact in this interface we can see statistics in real time.

We recommend access the official website of the TP-LINK TX-6610 where you will find all the details about this ONT. Currently we do not know when it will go on the market or at what price it will.

ESnet, the world’s fastest network used by NASA and CERN

One of the fastest moving things in our day is science. So much so that the conventional Internet is no longer fast and powerful enough. Since institutions like NASA see as an undeniable risk the fact that information travels at only a few gigabits per second, little by little its own “super-internet” network has been created, This utopian network used by eminent scientific-technological organizations such as NASA or CERN has been baptized with the name of ESnet.

We are talking about a precise, specific and closed network for researchers from all over the world, although at the beginning it was founded by the US Department of Energy (DOE). An exclusive network that, although it is not the first that exists with this same purpose, in its revealing evaluation in November 2013 it reached the dizzying transmission speed of 91 gigabits per second, a true record.

More than 20,000 kilometers of optimized fiber optics for research

Energy Sciences Network is the acronym for ESnet, and is managed and maintained by the qualified staff of the Lawrence Berkeley National Laboratory. As detailed on its website, among other users, ESnet serves more than 40 research centers, including among its ranks all the numerous supercomputers and scientific instruments of the entire American national laboratory system.

In the introduction we talked about how ESnet is a network restricted to scientific-technological use and the public does not have access to it, but that does not mean that its reach is only within US borders. This entire network is made up of an infrastructure of more than 20,000 kilometers of fiber optics that connects with more than 140 commercial and research networks throughout the world..

And we also indicated at the beginning that scientific matters have a very broad weight in the full sense of the expression. Priceless jobs like Human Genome Project or the research carried out in the Large Hadron Collider-CERN generate a colossal volume of data and a network with such a wide width is urgently necessary for such extensive information to flow from one laboratory to another, sending volumes equivalent to those of a hard disk as if sending a standard email from a weight of 25 Mb of limit will be.

Traffic on the ESnet has increased 10 times on average in every four years

It’s more, ESnet traffic has increased an average of 10 times every four years since it exists (it was born in 1986), which is an excellent sign (after all, the more traffic, it will mean an increase in research) and it is an indicator that the ESnet network has to be updated and progressed with so as to adapt to the needs of all the members who join it. The current generation is the fifth generation of the ESnet, which has been active since November 2012, built and developed from a router Alcatel-Lucent 7750 and reaching 44 times the capacity of the previous generation, according to the eminent DOE.

What about NASA?

The American space agency, or NASA, is part of the renowned organizations that use this important network, and in November 2013 they managed to transfer at 91 gigabits per second between the Goddard Center, located in Greenbelt, Maryland northwest of Whasington DC, and the SC13 supercomputer located in Denver, beating the then current speed record (being subsequently surpassed by Alcatel-Lucent and BT, with 1.4 terabits / second).

In addition, as detailed in the scientific-technological magazine Wired when echoing the matter, the theory is that ESnet supports transfers at 100 gigabits / second, but in practice transfers are lower due to distance. But even so, the network is still in operation today, which can be seen by consulting in real time, with speeds around 70 gigabits / second and higher intensity peaks in which higher speeds are delivered.

The OSCARS (On-Demand Secure Circuits and Advance Reservation System) and LHCONE (CERN) circuits are systems designed for a small number of large transfers, almost the opposite of what happens with commercial networks today, although one of the more immediate purposes of ESnet is to be the pioneer of what is going to come to these mentioned transfer circuits, as Tony Celeste (Brocade’s sales director) qualified in Wired magazine.

Increasing petabytes is the goal of all roads today

The structured ancestor of the ESnet was the revolutionary (for the time) ARPAnet, network created and designated for the United States Department of Defense. Later, another vaunted specific network was developed, the Magnetic Fusion Energy Network (in 1976), to connect the current Energy Science Research Computing Center with other laboratories in the United States.

Later (in 1980) it was added, to existing networks, the High Energy Physics Network to connect the country’s particle physics researchers and thus start building a large network devoted entirely to research. But with time and various tests they saw that it did not make sense for several networks to be created and maintained for the same purpose, finally joining them all on the ESnet.

It is interesting to see how network traffic has been increasing since it exists. The DOE estimated that by 2016 the network would have to carry 100 petabytes of traffic of data per month and although reality tells us that they have not even exceeded 70, but at the rate we are walking it would not be surprising that exceed 100 in less than two years.

So we will see if the ESnet breaks another speed record and if little by little these capabilities also reach homes and commercial networks. Meanwhile, it is comforting to know that at least part of the researchers do not see their work limited by the infrastructure of current networks, and without a doubt the best synthesis of ESnet was made by Gregory Bell, former director of ESnet, in Wired magazine: “Our vision of the world is that scientific discoveries should not be limited by geography”.
