Building Residential Voip Gateways: a Tutorial
Building Residential VoIP Gateways: A Tutorial by T Y Chan and Debbie Greenstreet, Glenn Yancey and Kim Devlin-Allen, David Jarrett and Keith Buchanan, Sophia Scoggins PhD, Matt Harvill and Demetri Jobson VoIP Business Unit www.analogzone.com Building Residential VoIP Gateways: A Tutorial Part One: A Systems-Level Overview by T Y Chan and Debbie Greenstreet, VoIP Group, Texas Instruments Incorporated While voice-over-IP (VoIP) products have been deployed in the market for over seven years, recent announcements by service providers such as Vonage, AT&T, Sprint and others have created a flurry of activity by consumer equipment manufacturers racing to roll out residential VoIP gateway products. These low-cost devices are usually standalone boxes that provide VoIP functionality for POTS (plain old telephone system) via a broadband modem (usually cable or DSL). They serve as a bridge between the TMD/analog POTS world, and the IP-centric, packet-based world of the Internet. As with most consumer products, their designers are usually faced with meeting aggressive product cost targets along with tight development schedules. The product feature shopping list often includes features not only specific to the basic VoIP gateway functionality but to other ancillary functions as well. These include data bridging and routings, such as found in common residential router products, emerging voice and signaling security features such as voice encryption and IPSec, and quality of service (QoS) features necessary to troubleshoot and maintain residential VoIP services. This article is the first in a series intended to assist engineers by providing detailed design considerations for all major portions of VoIP residential gateway products. -

Modem? Router? Gateway? Making Sense of Your Home Networking Equipment
FACT SHEET Modem? Router? Gateway? Making sense of your home networking equipment Most of the time, you don’t need to know anything about how the water gets into your home—you just turn on the tap. And you don’t need to be an electrician to use your refrigerator; you just plug it in and you’re all set. With your home Internet service, it should be the same way. You shouldn’t need to know much about the technology to use it. But the reality is that it’s helpful to have a basic understanding of networking technology and the different pieces of equipment in your home that allow you to connect to the Internet. Why are there so many different names for these devices? One challenge relates to the names that technology experts use to refer to these devices, whether it’s your Internet service provider (ISP) or the sales person at the big box store. You’ve probably heard these devices called several different things, such as a modem, gateway, router, or maybe even an access point. What’s the difference between all of these devices? It can definitely be complicated. The first thing that’s important to understand is that these devices collectively perform two different functions: nnthey make it possible for your ISP to bring an Internet connection into your home; and nnthey make it possible for that connection to be converted to a Wi-Fi signal so you can get online wirelessly from any of your devices. One-device solution: residential gateway Sometimes both of these functions are combined in a single device, which is usually called a residential gateway. -

Maxlinear Full-Spectrum Capture™ DOCSIS® 3.1 Chipsets Power Hitron’S Full Duplex Demonstration
October 17, 2017 MaxLinear Full-Spectrum Capture™ DOCSIS® 3.1 Chipsets Power Hitron’s Full Duplex Demonstration CARLSBAD, Calif.--(BUSINESS WIRE)-- MaxLinear, Inc. (NYSE:MXL), a leading provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, today announced that Hitron Technologies Inc. (TAIEX: 2419), a leading global telecommunications networking company, has picked MaxLinear front end receivers as part of a successful coexistence demonstration of its CODA family of DOCSIS® 3.1 cable modems in a Full Duplex (FDX) DOCSIS 3.1 demonstration network. The demonstration made use of MaxLinear's MxL277 and MxL278 Full-Spectrum Capture™ (FSC™) digital cable front-end receivers and the MxL236 upstream programmable gain amplifier. The demonstration also utilized the Intel® Puma™ 7 DOCSIS 3.1 SoC. The use of FDX technology provides broadband operators a path to deploy multi-gigabit upstream data speeds, enabling operators to deliver symmetric internet access speeds equivalent to fiber while extending the life of their existing hybrid coax cable plants. As part of the demonstration, Hitron is showcasing how its CODA family of cable modems are interoperable with future FDX signal environments and are ideal for cable operators who wish to deploy future-proof consumer premise equipment (CPE). Hitron’s CODA-45 models feature a 5MHz -85MHz fixed mid-split and multiple GigE ports (depending on the model), among other features. The CODA-47 models may be switched to 204MHz high-split enabling upstream speeds of 1Gbps. As utilized in Hitron’s CODA cable modem models, the MxL277 and MxL278 DOCSIS 3.1 tuners offer significant advantages in an all IP-based delivery of multimedia content and cloud services. -
