Docsis 3.0 cable modem. Cable modem: characteristics, how to choose and connect. Achieving maximum network throughput

Let's get acquainted with the operating features of the modem, as well as data transfer rates using DOCSIS 3.0 technology in the Volya company network. How much practical speed Does it correspond to what is stated by the provider? How does the modem “behave” in operation, and also, what are the conditions for providing the device for home and business users?

Appearance and connection

Let me make a reservation right away - the Volya company has several types of modems that support DOCSIS 3.0 technology, and all of them are provided to users under certain conditions. But let’s not delve into the conditions for providing devices to the end user for now, but consider the features of a specific model - the device that I had for testing - Thomson TCM 470.

So, the device body is made of two colors of matte plastic – black and white. Of course, this combination cannot be called one that “catches”, but the device itself is attractive and this cannot be taken away.

It is impossible to say that black or white plastic color dominates in the body assembly - both are equally divided: the lower part of the body, as well as the front and rear walls, are made of black plastic, while the upper part, as well as the right and left side walls, are white.

Although the top of the modem is white, dust remains noticeably on the surface. Personally, I have been wiping the outer part of the modem case almost every third day, along with cleaning the room in which the device is located.

The build of the device is excellent. Despite the fact that the white part of the body seems to be “dressed” on the black one, and besides, it is already tactilely easy to feel that we are dealing with durable and somewhat massive materials, the gaps in the end turned out to be minimal, not to mention the play. Nothing wobbles, does not crunch, and is not distinguished by other examples of careless assembly.

There are many small holes on all walls of the case, except the front one. These are the so-called ventilation meshes. The air ventilation system is silent. It should also be noted that the capabilities of the ventilation system implemented in this modem are very modest - when working for at least 9-10 hours in a row, the body of the device heats up noticeably. It’s also true that even noticeable heating does not affect the functionality of the device at all.

The front panel contains various indicators displaying the status of processes in the system. It is not necessary to know their clear purpose, you just need to understand a simple thing - in order for the device to work correctly, it is necessary that the POWER, DS, US, and ONLINE indicators light up without winking, and only the indicator with the signature Link blinks. If this task completes, the device is working correctly.

If a user connects a router or other signal “distributor” to a Wi-Fi modem, he must “reset” the basic settings of the modem, which the system automatically assigns to the modem during the previous connection. To do this, just press and release the reset button, which is located on the rear side panel. After which you will only need to restart the computer, during which it is best to connect the router – a matter of a few minutes.

In addition to the reset button, on the same panel there is a terminal for connecting the cable coming from the distribution panel in the house or business center. There is also a port for connecting a cable that directly connects the modem itself to a computer or laptop, plus a button for switching the power supply of the device.

On the bottom working panel, in addition to many ventilation holes, there is a sticker with various technical data about the device, as well as two gaps for mounting the modem with screws on a wall or a vertical platform.

Practical speed indicators

The NetMeter utility, with the help of which all calculations were carried out, is interesting not only as a speed tester. What we have before us is a fairly simple and instantly easy to learn traffic “recorder”, with the help of which any user can keep detailed statistics of consumed traffic for a period - one day, a month, or just a session.

Other, no less interesting feature, this tester is the simplest way testing Internet speed in the mode of various characteristics of traffic consumption. For example, I personally really liked the ability to track speed when playing streaming video in various formats. To do this, I used the VideoLAN VLC Media player 0.8.5, which, as you know, works with almost all formats, and it’s also easy to launch a media file in it. All videos were played at a resolution of 720x576 pixels.

The average traffic consumption when playing video in VOB format was 1.15 Mbit/s. During playback of a DivX file, the maximum speed was 415 kbps, and while playing video in MPEG4 format, the peak speed for the “stream” was 1.85 Mbps. The size of each file did not exceed 1.5 GB.

Regarding speeds, the situation in this case is as follows. On Upload we were able to easily achieve the “up to 3 Mbit/s” stated by the provider. During the measurement, the speed was in a “floating” state – from 2.2 Mbit/s to 2.9 Mbit/s.

As for Download, in this case the spread in indicators turned out to be as follows. During the so-called peak loads on the network, the speed did not exceed 17-19 Mbit/s, and in the period from 7-8 am to 17-18 o'clock the indicators fluctuated from 30-35 Mbit/s to 55 Mbit/s.

Terms of service

For private users, the Volya company provides modems exclusively on a rental basis - they cannot be purchased. At least for now.

The cost of rent by the provider is included in the cost of one or another tariff plan. Depending on what speed the subscriber wants to order, there are several devices to choose from, including the Thomson TCM 470 described above, and some others, in particular Thomson TCW 690/710, Arris WBM750B/NU DOCSIS 3.0, etc.

For business clients the conditions are different. Both rental and purchase of devices are allowed here. At the moment, the list of devices offered by the provider is limited to two Arris WBM750B/NU and Scientific Atlanta EPC 3000. The price of the first is 389 hryvnia. The second one will cost 699 hryvnia. The cost of renting a modem for a business user is similar to the cost of renting a device for a home user.

Some results

Despite the fact that in practice the speed in Download mode does not reach the 150 Mbit/s declared by the provider, nevertheless, the speed in DOCSIS 3.0 is an order of magnitude higher than the previous standard. The user will be able to watch a video on YouTube in high resolution or an HD movie on-line, as well as perform a host of other tasks related to the need for high-speed Internet with clearly greater comfort than in the previous standard mode.

It's a little annoying that legal entities Today this service is still quite expensive. Although its popularity is gaining momentum, it is therefore possible that, at least in the direction of increasing the popularity of the service, the company will reduce prices in the foreseeable future.

pros

  • Almost 100% coverage in Kyiv;
  • The only provider providing Internet in the DOCSIS 3.0 standard;
  • An interesting offer from Volya Absolut - with speeds of up to 150 Mbit/s for 200 hryvnia per month for home users. This package is especially interesting when purchasing the new TV+Internet service (http://volia.com/bundle/price). In this case, the monthly fee is reduced by almost half. For example, for the same 200 hryvnia you can buy a so-called “bundle” - a basic TV package (more than 80 channels) and an Internet package with a speed of up to 150 Mbit/sec.
  • Wide range of tariff plans in general;
  • Good speed for streaming video;
  • Stable connection

Minuses

  • For business clients the cost is quite high;
  • Speed ​​restrictions are possible if the fair use policy is violated for home users. Although there is a plus - less than 1% of users fall into this limitation.
They tested it in Ukraine, and one of the operators is preparing it.

Over Cable or DOCSIS is an international telecommunications standard that allows data transmission to be added to an existing high-bandwidth coaxial cable television system. This is important for both Internet users and Internet providers because it allows you to increase Internet speeds without replacing coaxial cable networks. On a practical level, consumers will need to know which DOCSIS standard is needed when purchasing a cable modem.

Modem Connection Basics

DOCSIS allows you to use cable connections to serve high-bandwidth applications. It was created in March 1997. During this period, it went through several stages of improvements. The system includes a modem located at the user's premises, as well as devices located elsewhere, usually at the central station of the provider company or at an intermediate node.

There are two main components of DOCSIS: the physical layer (PHY) and the media access control (MAC) layer. The physical layer refers to the wiring and routing equipment used, and the transmission of data across these various physical systems. In general, faster transfer speeds mean better performance. However, there are several limitations in terms of physical distance.

These restrictions affect the areas where a DOCSIS 3.0 cable modem and other infrastructure can be installed, which affects their speed and price. MAC layer is designed for intelligent control at any time a huge amount processed information, which allows for a critical level of organization that prevents frequent traffic jams caused by counter signals.

The evolution of Internet transmission speed

Overall, there have been three different major iterations of DOCSIS over the years: 1.x, 2.x, and 3.x. The original specifications 1.0 and 1.1 had an operating limit of 38 Mbps for transfer speeds and only 9 Mbps for speed increases. As technology evolved over the next few years, it was necessary to organize operations so that cable providers had greater flexibility as speeds improved and service levels increased. This led to the creation of DOCSIS 2.0 in 2002.

DOCSIS 2.0 did not introduce new features to reduce network speed, but it tripled the speed, allowing 30 Mbps connections. The most significant changes occurred in 2008 with the introduction of DOCSIS 3.0. This new iteration was a format that significantly increased speeds to 1.2 Gbps and 200 Mbps respectively. This was a huge leap, with DOCSIS 3.0 including the introduction of channel communications.

It allows you to assemble or combine multiple channels downstream and upstream with improved speeds across the entire range. With a channel connection, the more channels present, the better. So, installing 16 channels downstream and 4 upstream or 16x4 provides fast speed, and a 24x8 system even faster.

Latest Integration Standard

In 2016, DOCSIS 3.1 was released, which led to a sharp jump in speeds, including in the downstream direction. This iteration brought speed packages of up to 10 Gbps and 1 Gbps, respectively. Today, work is already underway to develop a new iteration, usually called DOCSIS 3.1 Full Duplex. This version will support symmetrical 10 Gbps up and down speeds.

It is inevitable that DOCSIS Cable Modem will continue to evolve to accommodate new technologies and user requirements around the world. Consumers should stay on top of these changes to ensure they can upgrade to cutting-edge models in a timely manner.

As 4K and UHD become more common for both wireless and wired networks, their options are increasing in terms of volume and convenience. Therefore, there are still many exciting developments to come in the DOCSIS field in the coming decades.

Buy or rent

If a user leases a cable modem from their ISP, purchasing is an option that will save them hundreds of dollars in rental fees over the life of the device. Some companies charge about $120 annually for rent, and given the low cost of modems, most will pay for themselves very quickly. Additionally, choosing a modem for your personal needs allows you to get the most out of your internet plan, and the network performs better than rental equipment.

Not every modem is suitable for all types of Internet services. Cable internet will not work with because they use different ways delivery. DSL uses the telephone's terrestrial infrastructure. If the Internet provider is also an operator landline phone you will probably need the appropriate type of DSL.

More advanced users recommend a modem and router combo if you need an inexpensive and compact replacement for a rental device. However, keep in mind that they do not give much control over the router. If one device breaks, both will need to be replaced.

How a cable modem works

It provides data transmission over cable television networks and can be connected directly to the TV socket. This places it between the user's cable connection and the computer. It can also be connected to a computer via USB or network cable. If the user wants to connect several computers, then in addition to the modem, a compatible router or a combined device is needed that will combine both functions.

The data sent by the computer must be converted into a suitable format in order to be able to transmit it on special frequencies via a television cable. Today, Internet providers mainly provide combination devices from a cable modem router, which allows you to connect via WLAN to the Internet.

Multiple devices with one IP

The ISP only provides one IP address. But a situation often arises when you need to connect several devices via WLAN in parallel to the network. This is possible if this IP address is not directly associated with the PC, but with a router that connects the internal network to the outside world. It works with a public IP address. However, the internal network uses a separate block of IP addresses.

In theory they range from 192.168.0.0 to 192.168.255.255. In practice they are almost always 192.168.1.1 or 192.168.1.50. Addresses starting with 192.168 are, by definition, always private IP addresses. Devices with the same IP addresses are located on many millions of small and large networks. Almost every personal router defaults to internal IP 192.168.1.1.

It is very important in what order the devices are turned on. First, turn on the cable modem and wait until the LED lights up, indicating that it is ready to start and connected to the Internet. Then the router is started. Experience shows that this happens a little faster than with a modem. Only at the moment when they are ready, the terminals connect to the network in any order: mobile phone, tablet, laptop, desktop PC.

Connecting and setting up the router

Setting up network equipment with routers is much easier today than before. Before you connect your cable modem, it's helpful to understand which type is best for a fast connection to avoid unwanted problems in the future. Connection to Motorola:

  1. Open an Internet browser. In the address field, enter for Motorola routers: 192.168.100.1, for the modem: 192.168.0.1.
  2. Press "Enter". Default username: admin. Default password: motorola, all lowercase letters.
  3. Click “Login”. If you can't login with 192.168.0.1, try using 192.168.100.1.
  4. Make sure that the username is: admin and the password is: motorola.
  5. Make sure that the connected Motorola cable modem model begins with the letter “M”, example: MB8600, MG7550, MD1600.
  6. Set the device to factory default settings. Here you will need a pin or a straightened paper clip.
  7. This is done when the power is turned on. Find the RESET hole at the back of the device.
  8. Press the RESET hole with a paper clip for about 25 seconds. Wait until the device connects again.
