Download or read book Legacy Technology: All About T1 written by Eric Coll. This book was released on 2023-02-09. Available in PDF, EPUB and Kindle. Book excerpt: Legacy Technology: All About T1 This module provides detailed information on the carrier system technology called T1. T1 used to be a principal subject of telecommunications courses, but is now relegated to the back of the book, as T1 is a technology running at 1.5 Mb/s on copper wires, replaced with Gigabit/s Optical Ethernet on fiber. That said, there are thousands of T1 circuits installed and in use, and some readers of this book have picked it precisely to learn about T1 because they have been tasked with supporting it, or auditing an existing installation. Power companies, the military and government still have T1s in place, along with T1s at big organizations that are no longer being used, but have been forgotten and are still being paid for each month... a small but appreciated part of any phone company’s revenue. This chapter on T1 also provides a very detailed explanation of synchronous Time-Division Multiplexing, framing and channels. Since the principles of operation of legacy SONET fiber-optic transmission systems are the same as T1, learning about T1 is also learning about SONET.

Telecom 101 covers the technologies, the players, the products and services, jargon and buzzwords, and most importantly, the underlying ideas... and how it all fits together. This is the best comprehensive book on telecommunications available anywhere: based on the course materials for Teracom's famous instructor-led Course 101 Broadband, Telecom, Datacom and Networking for Non-Engineers, the selection of content, its order, timing and pacing has been tuned and refined over years to effectively define and deliver the core set of technical knowledge needed by anyone serious in the telecom business today. In one book, you get consistency, completeness and unbeatable value: a wealth of clear, concise, organized knowledge, impossible to find in one place anywhere else! Our approach can be summed up with a simple philosophy: Start at the beginning. Progress in a logical order. Build one concept on top of another. Finish at the end. Avoid jargon.

Book Synopsis Switching to VoIP by : Theodore Wallingford

Download or read book Switching to VoIP written by Theodore Wallingford. This book was released on 2005. Available in PDF, EPUB and Kindle. Book excerpt: More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It's the only thing left between you and a modern telecom network.
