what is an upstream channel

Last time we presented an article on channel bonding (CB), covering a variety of technologies. 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. Tom's Guide is part of Future US Inc, an international media group and leading digital publisher. Please deactivate your ad blocker in order to see our subscription offer, cable modems. Reviewed by: Michelle Seidel, B.Sc., LL.B., MBA. Finally, you can always just call your ISP. 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. It's not at all clear what the average user is supposed to glean from this. (Google "(brand name) modem IP address" on your phone, or on another network, if the instructions don't include it.) Using an assembly plant as the center of a chain helps to explain upstream and downstream activity more clearly. You might hear the words "upstream" and "downstream" when referring to various stops along the chain. This document describes how to check the three signal levels to be within the acceptable level for the modem operate properly. Getting very peed off with this now. • Comcast-compatible modems Find the perfect cable modem for your home by knowing the terminology. DOCSIS stands for "Data Over Cable Service Interface Specification." 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. The general objective across the board is to get finished products to the consumer in the most cost-effective manner. 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). Downstream: The opposite of upstream. Inconsistency in levels of consumer demand for a product greatly influences activities all along the supply chain. 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're still using a router provided by your cable company, you should send it back and buy a new router immediately. 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. Upstream: This means away from you and towards the internet and your internet service provider. 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. Distributors, wholesalers and retailers all strive to carry inventory in quantities needed to fulfill customer orders without overstocking. 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. Just remember that all other things being equal, higher numbers are better. Git set-upstream. 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. 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. 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. 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. Namely the "puma 6" . Visit our corporate site. 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. 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. 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. Most modems are compatible with any cable company, but some aren't. 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. A MAC domain is a logical sub-component of a Cisco … With git set upstream, you can choose where your current local branch will flow. Upstream channel bonding has a lot in common with downstream channel bonding. The upstream channels, however, only half of them lock (channels 1-4). Upstream is the information you send from your home to the internet. Big companies like Comcast and Cox support just about anything, but smaller networks may not. Good Upstream power levels are within 38-48 dBmV. Downstream is OK Upstream is either very bad or non existent. 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. That's really all you need to know to buy a modem: design, DOCSIS, channels, speed and compatibility. It's the protocol that lets an ISP provide internet service through a coaxial cable. For small homes and apartments, they can get the job done, although Tom's Guide doesn't usually recommend modem-router hybrids. 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). What's tougher, however, is picking the best cable modem. Also, remember that "Mbps" means "megabits per second," not "megabytes per second." If something goes wrong, your entire internet setup is shot, and it's easier — and cheaper — to upgrade modems and routers separately. Some ISPs offer an automated process to do this through an internet browser, but it varies depending on the provider and model. An upstream channel is one in another frequency band that is used to send signals from the user back to the headend. The good news is that it's simply a description of how many downstream and upstream channels a modem has. The other half (5-8) won't lock. To view the upstream and downstream power levels: Launch a web … Another downstream activity is customer service in the retail store, when the product finally reaches the consumer. Channel members share in responsibilities of sourcing quality materials, arranging for low-cost logistics and transportation and garnering marketplace demand. Roughly speaking, that correlates with how much download data your ISP can provide at any given time. NY 10036. With the assembly plant as the focus of the supply chain, upstream activity includes suppliers of raw materials, such as aluminum and copper. A supply chain includes all the businesses involved in getting a finished product to the market. Outdoor Channel is available on a few of the major live TV streaming services. When trying to decide which one is best for you, you’ll want to weigh the cost, the other channels … (Remember the discussion earlier about downstream versus upstream channels.). Learn the particular stops along the way where the terms are used to know what they refer … In computer networking, upstream refers to the direction in which data can be transferred from the client to the server ( uploading ). The terms upstream and downstream oil and gas production refer to an oil or gas company's location in the supply chain. 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. High upstream power (usually 58+) on all upstream bonded channels. Upstream or upload speed is the term given to the data that your computer sends out to the Internet. A downstream cable "channel" sends data from the cable company "headend" to you. The upstream channel bonding method enables a CM to transmit data to a Cisco CMTS router on multiple upstream channels simultaneously. There are three methods of checking whether a modem is compatible with your ISP, although only one of them is foolproof. The last thing you'll have to check is whether your modem is compatible with your ISP. — without ever actually explaining what these features mean, or why they might be beneficial to your home setup. 4 channels is 4 times that (108 Mbit/sec). An explanation of upstream and downstream is relative to location along the supply route. 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. • Cox-compatible modems. • Spectrum-compatible modems So it is better if we use the parent/child terms in place of upstream/downstream in case of time/history. From looking at other postings, I gather that my downstream channels may not be bonding properly. Even the modem you picked "netgear cm 700" with the new and improved chipset have problem. 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. Manufacturers, wholesalers and retailers may cooperate in the major downstream activity … Transporting or shipping to the plant is another example of upstream activity. (You're dependent on your ISP to issue these firmware updates, and they don't always come out in a timely fashion.) 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. (If you're still using a router provided by your cable company, yo… Don't sweat this part too much, unless you want the absolute top-tier packages your cable company can provide. In some operations, the same company may own multiple components of the supply chain. 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. Of course, this could change in the future, but by then, DOCSIS 3.1 modems will probably be cheaper. 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… Any new modem you buy should have at least 16 downstream channels; anything less is probably either old or underpowered. This means information coming down from the internet to your modem. Like downstream channel bonding, upstream bonding consists of two or more channels active as an Upstream Broadcom says it's issued a fix, so you can always check with your ISP to make sure that your modem is secure. The second method is to check the Approved Modems website, which exists for this very purpose. The company must also be willing to push out firmware updates on a regular basis, which is easier for some modems than for others. 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 DOCSIS 3.0 and 3.1 are just version numbers. First off, whatever you see advertised is always a download speed, never an upload speed. Upstream channels refers to the data that your computer sends out to the Internet. So if a modem advertises a speed of 1 gigabit, that means it can pull up to 1,000 Mbps from your ISP. Sometimes the concept is referred to as the "downstream the supply chain" and "upstream the supply chain.". 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. 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. A downstream system is a system that receives data from the Collaboration Server system. 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, … 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. 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. First things first: How happy are you with your router? Supply chain management takes into account suppliers, manufacturing plants, distributors, wholesale warehouses and retail stores. The git set-upstream allows you to set the default remote branch for your current local branch. The number before the "x" represents how many downstream channels the modem has. If you subscribe to a 50-Mbps plan, your maximum download speed will be somewhere in the neighborhood of 7 megabytes per second. When an order cannot be filled in a timely manner, this is called a "stock-out" and activity stalls. (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.). 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. Gigabit speeds! The focus of this article will be on the mechanics of upstream channel bonding and how it works more from a DOCSIS protocol perspective. The exact differences between them basically boil down to speed and the number of simultaneous channels. You did not address the problem a few modems have. Downstream from the assembly plant are distributors, shipping partners, and point-of-sale stops along the way, such as wholesalers and retailers. Activities upstream could include a supplier mining these materials to fulfill orders. 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. That's fast, but you're not going to get a 50-gigabyte game or an enormous cache of photos in mere minutes. Subsequently, question is, what is upstream channel? There was a problem. 3) In CATV, a downstream channel is one used to transmit signals from the headend to the user. 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). This represents the total bandwidth of data your computer can send out to the Internet each second at full speed. It just means that your modem can provide broadband internet access. My internet works fine, and my speed matches my tier (250 Mbps). 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. New York, An upstream system is any system that sends data to the Collaboration Server system. The upstream light is amber, and I find that I occasionally have connectivity problems. Once you get your new modem home, you'll probably have to call up your ISP and provide the device's MAC address. 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. Using a river analogy to illustrate the flow of data, upstream is sending your data back to where the river stream is coming from. I am guessing the fact i only have 2 upstream channels may be related to why i am having issues. 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. Future US, Inc. 11 West 42nd Street, 15th Floor, You'll see descriptors like "up to 600 Mbps" completely devoid of context. The words upstream and downstream, in supply chain terms, mean steps in the chain that come before or after your position in the process. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. When you buy a modem, you'll see one acronym featured very prominently: DOCSIS. Generally, the upstream speed capable via cable modems ranges from 400 kilobits per second to 600 kilobits per second (Kbps). Good Downstream power levels are within -7 to +7 dBmV. That said, the occasional security issue does pop up. Supply Chain Quarterly: Supply Chain Segmentation, 10 Steps to Greater Profits. Upstream Power refers to the line signal from the cable modem to transmit data back to the cable provider. 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. "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." DOCSIS 3.1! Your computer uploads data anytime you send an email or post a picture to Facebook or a server using FTP. Your cable modem is connected to a coaxial cable that leaves your house. 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. I tried changing the wi-fi channels used. I tried power-cycling the modem. Suppose the materials are on order but not on hand. When operations are running smoothly, the distributors ship orders on time. (Eight bits make a byte.) 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. 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. So basically I have a "24x4" modem router. The focus of activity would likely be to mine the requested materials as quickly and efficiently as possible. 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. Think of wherever that goes as upstream. With that in mind, here's an updated guide that can (hopefully) demystify modem specs. There's no hard-and-fast reason for this; it's just the way it is. 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. In the reference of time/history, it can be unclear, because upstream in time means downstream in history, and vice-versa. This was last updated in September 2005 The first, and simplest, is to just google "[ISP] compatible modems." It's not a very difficult decision. First things first: How happy are you with your router? Had some wonkiness with the network extender downstairs this afternoon and had to power cycle the modem/router a couple times. — Chris Gascoyne, 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… Please refresh the page and try again. Some of the pages haven't been updated in a while, but it's a good place to start. 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. When you send something upstream, you are sending it back to the original authors of the repository. Upload speeds tend to be much slower — somewhere in the neighborhood of one-quarter the download speed. 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.). 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. You will receive a verification email shortly. 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. Investing in one of the best antivirus programs also offers some, though not total, protection. My ISP is comcast. Downstream SNR (Signal to Noise Ratio) refers to the signal being sent in relation to the noise on the line. Note that with plain port channels, each physical link that makes up one end of the port channel must terminate on the same switch. The CMTS sends correction signals to each cable modem during station maintena… Thank you for signing up to Tom's Guide. This differs greatly from downstream not only in theory and usage, but also in that upstream speeds are usually at a premium. 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. 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. If you’re a customer of a cable provider (known as a multiple services operator or MSO) delivering data/video/voice services, you’re … 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. All the high speeds may seem tempting, but remember: You can't draw more data than you pay for from your ISP. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. My question would be: Is it common that not all the channels lock? 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! See what your search turns up. 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). One important downstream activity is inventory management. 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.
