what is an upstream channel

Of course, this could change in the future, but by then, DOCSIS 3.1 modems will probably be cheaper. I've lived in my current house for over two years, and the upstream/downstream indicator lights on my modem have always been blue, apparently indicating bonded channels. Your cable modem is connected to a coaxial cable that leaves your house. Distributors, wholesalers and retailers all strive to carry inventory in quantities needed to fulfill customer orders without overstocking. You may have to sit on hold for a while, but it's the only way to get a 100-percent definitive answer on whether a modem you want to buy is supported. When you buy a modem, you'll see one acronym featured very prominently: DOCSIS. This document describes how to check the three signal levels to be within the acceptable level for the modem operate properly. Think of wherever that goes as upstream. Reviewed by: Michelle Seidel, B.Sc., LL.B., MBA. You will receive a verification email shortly. Learn the particular stops along the way where the terms are used to know what they refer … New York, NY 10036. In computer networking, upstream refers to the direction in which data can be transferred from the client to the server ( uploading ). First things first: How happy are you with your router? With that in mind, here's an updated guide that can (hopefully) demystify modem specs. 2:15 p.m. – Live landing commentary on the NASA TV Public Channel and the agency’s website, as well as the NASA App, YouTube, Twitter, Facebook, … When operations are running smoothly, the distributors ship orders on time. Finally, you can always just call your ISP. When an order cannot be filled in a timely manner, this is called a "stock-out" and activity stalls. I am guessing the fact i only have 2 upstream channels may be related to why i am having issues. One important downstream activity is inventory management. Downstream: The opposite of upstream. The other half (5-8) won't lock. Just about every modem provides many more downstream channels than upstream ones, because ISPs and end users alike are more concerned with downloading content than uploading it. It's not at all clear what the average user is supposed to glean from this. Modern routers are compatible with just about every modem on the market, so just make sure your firmware is upgraded, and you'll be all set. What's tougher, however, is picking the best cable modem. This differs greatly from downstream not only in theory and usage, but also in that upstream speeds are usually at a premium. Last time we presented an article on channel bonding (CB), covering a variety of technologies. Transporting or shipping to the plant is another example of upstream activity. Activities upstream could include a supplier mining these materials to fulfill orders. At the top of my list is making sure that pre-equalization is enabled on every return port of your cable modem termination system (CMTS). An explanation of upstream and downstream is relative to location along the supply route. Most modern modems use either the DOCSIS 3.0 or 3.1 protocols, but neither manufacturers nor retailers ever really explain what this means or why the distinction is important. (Eight bits make a byte.) It's not a very difficult decision. The git set-upstream allows you to set the default remote branch for your current local branch. Once you get your new modem home, you'll probably have to call up your ISP and provide the device's MAC address. Thank you for signing up to Tom's Guide. Namely the "puma 6" . Using an assembly plant as the center of a chain helps to explain upstream and downstream activity more clearly. Plain old port channels can be used between most Ethernet switches and many server NIC drivers support LACP as well for providing a port channel between a server and its upstream switch. Downstream from the assembly plant are distributors, shipping partners, and point-of-sale stops along the way, such as wholesalers and retailers. Unlike routers, which have settings you can adjust to make them more secure, there's not a lot of security considerations to keep in mind when shopping for a router. Please refresh the page and try again. — without ever actually explaining what these features mean, or why they might be beneficial to your home setup. For example, a software vulnerability in modems that use Broadcom's systems-on-a-chip could allow a hacker to seize control of the modem and serve up malicious websites. In the reference of time/history, it can be unclear, because upstream in time means downstream in history, and vice-versa. A couple years back, I bought a new cable modem (a Netgear CM700-100NAS, which is thoroughly decent, albeit somewhat expensive at the time), and I realized that modem manufacturers often highlight terrific features — 32 x 8! Tom's Guide is part of Future US Inc, an international media group and leading digital publisher. The Upstream Channel Bonding (USCB) feature helps cable operators offer higher upstream (US) bandwidth per cable modem (CM) user by combining multiple radio frequency (RF) channels to form a larger bonding group at the MAC layer. The upstream light is amber, and I find that I occasionally have connectivity problems. (If you're still using a router provided by your cable company, you should send it back and buy a new router immediately. A small-business owner since 1999, Benge has worked as a licensed insurance agent and has more than 20 years experience in income tax preparation for businesses and individuals. Git set-upstream. Also, remember that "Mbps" means "megabits per second," not "megabytes per second." When you look at a modem, you'll often see a number somewhere in its description, which can be anything from 8 x 4 to 32 x 8. But once you understand what all the arcane terminology means, you'll find that there are probably a handful, rather than dozens, of choices worth considering. You'll see descriptors like "up to 600 Mbps" completely devoid of context. In the above example, we have three steps: 1. collecting parts 2. assembling the parts 3. painting the assembly A production process is very similar to a river, so it’s easy to grasp that as the process goes from one step to t… To view the upstream and downstream power levels: Launch a web … The company must also be willing to push out firmware updates on a regular basis, which is easier for some modems than for others. That's really all you need to know to buy a modem: design, DOCSIS, channels, speed and compatibility. Vicki A Benge began writing professionally in 1984 as a newspaper reporter. The upstream throughput possible is 30.72 Mbit/s per 6.4 MHz channel (approximately 27 Mbit/s after overhead), or 10.24 Mbit/s per 3.2 MHz channel (approximately 9 Mbit/s after overhead). The focus of activity would likely be to mine the requested materials as quickly and efficiently as possible. If you upgraded your router recently but bought your modem sometime around the signing of the Declaration of Independence, you probably just need a standalone cable modem. (Remember the discussion earlier about downstream versus upstream channels.). — Chris Gascoyne, Upstream is the information you send from your home to the internet. 3) In CATV, a downstream channel is one used to transmit signals from the headend to the user. © "Upstream Works customer engagement solutions effectively enable our clients' digital business transformation goals with the integration of all CX channels, data, and systems and a unified desktop for consistent, personalized experiences that meet and exceed customer expectations." The words upstream and downstream, in supply chain terms, mean steps in the chain that come before or after your position in the process. First things first: How happy are you with your router? Another downstream activity is customer service in the retail store, when the product finally reaches the consumer. High upstream power (usually 58+) on all upstream bonded channels. Had some wonkiness with the network extender downstairs this afternoon and had to power cycle the modem/router a couple times. Outdoor Channel is available on a few of the major live TV streaming services. This was last updated in September 2005 First off, whatever you see advertised is always a download speed, never an upload speed. When it comes to choosing a cable modem for your home internet service, you have two choices: Pay up each month to rent a beat-up, ancient model from your internet service provider, or buy your own brand-new device for a fraction of the cost over time. If, like me, you upgraded your router recently but bought your modem sometime around the signing of the Declaration of Independence, you probably just need a stand-alone cable modem. Upstream Channel 0: Lock Status: Locked: Modulation: 64QAM: Channel ID: 1: Symbol rate: 5120 Ksym/sec: Upstream Frequency: 16900000 Hz: Upstream Power: 38.5000 dBmV Upstream or upload speed is the term given to the data that your computer sends out to the Internet. There's probably an official list somewhere on the ISP's own website — Comcast and Cox both list compatible modems, for example — although the list may not be up-to-the-minute current. Please deactivate your ad blocker in order to see our subscription offer, cable modems. All the high speeds may seem tempting, but remember: You can't draw more data than you pay for from your ISP. If your router is also looking a bit long in the digital tooth, though, a cable modem/router combo — also called a gateway — is one possible way to go. Find the perfect cable modem for your home by knowing the terminology. Modern routers are compatible with just about every modem on the market, so just make sure your firmware is upgraded, and you'll be all set. The general objective across the board is to get finished products to the consumer in the most cost-effective manner. It just means that your modem can provide broadband internet access. Sometimes the concept is referred to as the "downstream the supply chain" and "upstream the supply chain.". Some of the pages haven't been updated in a while, but it's a good place to start. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. (If you're still using a router provided by your cable company, yo… That said, the occasional security issue does pop up. For small homes and apartments, they can get the job done, although Tom's Guide doesn't usually recommend modem-router hybrids. My ISP is comcast. The last thing you'll have to check is whether your modem is compatible with your ISP. A supply chain includes all the businesses involved in getting a finished product to the market. As with modems, cable companies usually charge exorbitant rental fees for subpar routers, and it takes less than a year for a new router to pay for itself.). As an example, when you request the webpage www.google.com, your initial request out to google uses your upstream channels and when google delivers you the contents of their webpage, that uses the downstream channels. DOCSIS 3.0 and 3.1 are just version numbers. Upstream: This means away from you and towards the internet and your internet service provider. The focus of this article will be on the mechanics of upstream channel bonding and how it works more from a DOCSIS protocol perspective. This is usually printed on the bottom of the modem, but if not, you can access the modem's IP address after plugging it in via Ethernet. There's no hard-and-fast reason for this; it's just the way it is. I tried power-cycling the modem. From looking at other postings, I gather that my downstream channels may not be bonding properly. An upstream system is any system that sends data to the Collaboration Server system. While the use of two SC-QAM channels generated about 25 Mbit/s upstream, the 45.5MHz of spectrum used for the OFDMA piece pumped out about 365 Mbit/s. The bottom line is that if your ISP offers internet speeds of more than 1 gigabit (1,000 Mbps, or megabits per second), a DOCSIS 3.1 router is a better investment. There are three methods of checking whether a modem is compatible with your ISP, although only one of them is foolproof. Inconsistency in levels of consumer demand for a product greatly influences activities all along the supply chain. So it is better if we use the parent/child terms in place of upstream/downstream in case of time/history. Supply Chain Quarterly: Supply Chain Segmentation, 10 Steps to Greater Profits. This represents the total bandwidth of data your computer can send out to the Internet each second at full speed. Using a river analogy to illustrate the flow of data, upstream is sending your data back to where the river stream is coming from. In some operations, the same company may own multiple components of the supply chain. The upstream channel bonding method enables a CM to transmit data to a Cisco CMTS router on multiple upstream channels simultaneously. Good Upstream power levels are within 38-48 dBmV. Channel bonding is a method by which smaller bandwidth upstream channels are bonded together to create a larger upstream bonding group in the MAC domain. The number before the "x" represents how many downstream channels the modem has. Supply chain management takes into account suppliers, manufacturing plants, distributors, wholesale warehouses and retail stores. 4 channels is 4 times that (108 Mbit/sec). DOCSIS 3.1 supports a downstream throughput with 4096-QAM and 25 kHz subcarrier spacing of up to 1.89 Gbit/s per 192 MHz OFDM channel. Future US, Inc. 11 West 42nd Street, 15th Floor, Buying an extremely fast modem is more about future-proofing your setup than pushing it to its limits, unless you're willing to spend a tremendous amount of money on a monthly plan. upstream channels Compliant with CableLabs® specifications for DOCSIS 3.1 Compliant with CableLabs® specifications for DOCSIS 3.0 (32x8 bonding) 4 VIAVI OneExpert™ CATV Data Sheet Specifications Continued Displayed DOCSIS Results Top level Number of bonded channels… A downstream cable "channel" sends data from the cable company "headend" to you. But since the average broadband speed in the United States is somewhere in the neighborhood of only 66 Mbps, DOCSIS 3.0 will be fine for the vast majority of users. Upload speeds tend to be much slower — somewhere in the neighborhood of one-quarter the download speed. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. Gigabit speeds! Good Downstream power levels are within -7 to +7 dBmV. These devices are exactly what they sound like: digital receivers that can pick up a signal via a coaxial cable and then transmit the wireless signal across an entire house. (You're dependent on your ISP to issue these firmware updates, and they don't always come out in a timely fashion.) Even the modem you picked "netgear cm 700" with the new and improved chipset have problem. Some ISPs offer an automated process to do this through an internet browser, but it varies depending on the provider and model. DOCSIS stands for "Data Over Cable Service Interface Specification." A downstream system is a system that receives data from the Collaboration Server system. With git set upstream, you can choose where your current local branch will flow. You might hear the words "upstream" and "downstream" when referring to various stops along the chain. Generally, the upstream speed capable via cable modems ranges from 400 kilobits per second to 600 kilobits per second (Kbps). An upstream channel is one in another frequency band that is used to send signals from the user back to the headend. That's fast, but you're not going to get a 50-gigabyte game or an enormous cache of photos in mere minutes. If something goes wrong, your entire internet setup is shot, and it's easier — and cheaper — to upgrade modems and routers separately. Big companies like Comcast and Cox support just about anything, but smaller networks may not. A MAC domain is a logical sub-component of a Cisco … Called vertically integrated, this type of company can have upstream and downstream activities occurring simultaneously under the same upper management and occasionally at the same location. So if a modem advertises a speed of 1 gigabit, that means it can pull up to 1,000 Mbps from your ISP. DOCSIS 3.1! Manufacturers, wholesalers and retailers may cooperate in the major downstream activity … Downstream and upstream power levels are important when determining if the cable line that is connected to your cable modem or modem router is receiving sufficient power. • Spectrum-compatible modems (If your ISP cannot give you a definitive answer, ask to speak to a manager or a specialist, or consider getting a new ISP; this should not be a hellaciously difficult question.). • Comcast-compatible modems Just remember that all other things being equal, higher numbers are better. Most modems are compatible with any cable company, but some aren't. Upstream channels use narrower channels of bandwidth between 200kHz and 6.4 MHz, but typically 3.2MHz with a typical throughput (in modern systems) of 27 Mbit/sec. Like downstream channel bonding, upstream bonding consists of two or more channels active as an Upstream When you send something upstream, you are sending it back to the original authors of the repository. Upstream channel bonding has a lot in common with downstream channel bonding. Downstream SNR (Signal to Noise Ratio) refers to the signal being sent in relation to the noise on the line. We enable pre-equalization because it allows the CMTS and modems to overcome many upstream impairments simply by sending updates to modems so that they can predistort their radio frequency (RF) transmissions to adapt for the RF impairments. Let’s start with a simple production process, even though it has nothing to with softwaredevelopment, so we can build on that to define upstream and downstream insoftware development. The second method is to check the Approved Modems website, which exists for this very purpose. especially if you are a gamer see https://www.theregister.co.uk/2017/05/01/netgear_puma_6_modems_trivial_to_crash/, settings you can adjust to make them more secure, a software vulnerability in modems that use Broadcom's systems-on-a-chip, PS5 restock coming this week — use these tips to get yours, Metro Exodus developer just gave gamers a big reason to skip Xbox Series S, The best Xbox Game Pass games to play now, DIY smart home: Why I’m using smart switches instead of smart lights, Apple patent reveals radical new design for iPhones and iPads. Roughly speaking, that correlates with how much download data your ISP can provide at any given time. Suppose the materials are on order but not on hand. Channel members share in responsibilities of sourcing quality materials, arranging for low-cost logistics and transportation and garnering marketplace demand. When trying to decide which one is best for you, you’ll want to weigh the cost, the other channels … I tried changing the wi-fi channels used. See what your search turns up. So basically I have a "24x4" modem router. With those specs in mind, all you need to do is pick a budget and a brand, and you'll be able to find at least a few models that match your specifications. My internet works fine, and my speed matches my tier (250 Mbps). Investing in one of the best antivirus programs also offers some, though not total, protection. Some of the most important things you can learn about a modem are its upload and download speeds — and yet, somehow, these always gets shoved about halfway down the page on a retailer's or manufacturer's website. I can't tell you which modem is right for your home, since that depends on your cable provider, your internet service package and your budget. You did not address the problem a few modems have. It's the protocol that lets an ISP provide internet service through a coaxial cable. Her business and finance articles can be found on the websites of "The Arizona Republic," "Houston Chronicle," The Motley Fool, "San Francisco Chronicle," and Zacks, among others. Downstream is OK Upstream is either very bad or non existent. Don't sweat this part too much, unless you want the absolute top-tier packages your cable company can provide. This means information coming down from the internet to your modem. The exact differences between them basically boil down to speed and the number of simultaneous channels. Today we’ll look more into depth at DOCSIS 3.0 or D3 channel bonding—CB for data delivered via coax to a cable modem (CM). The first, and simplest, is to just google "[ISP] compatible modems." Any new modem you buy should have at least 16 downstream channels; anything less is probably either old or underpowered. The CMTS sends correction signals to each cable modem during station maintena… Subsequently, question is, what is upstream channel? Visit our corporate site. My downstream connections are in the -2.2 to 0 range for all 24 but my upstream channels, of which there is only 2, show as 4.3 and 4.4 respectively (I know this needs to be x10 due to a bug, so they seem ok, but there is only 2 of them). A decent DOCSIS 3.0 modem ranges from $50 to $80; DOCSIS 3.1 modems tend to fall between $150 and $199, though prices are coming down to the lower end of that range. The good news is that it's simply a description of how many downstream and upstream channels a modem has. • Cox-compatible modems. If your modem is capable of pulling 1.4 gigabits but you subscribe to a plan that caps your speed at 25 Mbps, you're going to get 25 Mbps. The terms upstream and downstream oil and gas production refer to an oil or gas company's location in the supply chain. The upstream channels, however, only half of them lock (channels 1-4). Upstream Power refers to the line signal from the cable modem to transmit data back to the cable provider. My question would be: Is it common that not all the channels lock? Note that with plain port channels, each physical link that makes up one end of the port channel must terminate on the same switch. (Google "(brand name) modem IP address" on your phone, or on another network, if the instructions don't include it.) There was a problem. To integrate your Collaboration Server system with upstream and downstream systems, you need to create data sources, define import, export, or report jobs, and create message queues. You must first know the particular stops along the way to know exactly what they refer to and the activities that take place at these specific locations along the chain. Your computer uploads data anytime you send an email or post a picture to Facebook or a server using FTP. If you’re a customer of a cable provider (known as a multiple services operator or MSO) delivering data/video/voice services, you’re … Cable companies run enormous networks, and they want to be 100 percent certain that a product is compatible before they authorize it for use. If you subscribe to a 50-Mbps plan, your maximum download speed will be somewhere in the neighborhood of 7 megabytes per second. With the assembly plant as the focus of the supply chain, upstream activity includes suppliers of raw materials, such as aluminum and copper. Regardless of whether materials are upstream or products are downstream, the central focus of each business involved along the chain remains the same, to make sales and reap profits. Broadcom says it's issued a fix, so you can always check with your ISP to make sure that your modem is secure. Upstream channels refers to the data that your computer sends out to the Internet.
