Packed with information, authoritative, up to date, covering all major topics – and written in plain English – Telecom 101 is an invaluable textbook and day-to-day reference on telecommunications for non-engineers.

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 have been tuned, refined and constantly updated over years to effectively define and deliver the core set of technical knowledge needed by anyone serious in the telecom business today.

Telecom 101 Sixth Edition is right up to date with discussion of aircraft interfering with 5G in the C-band.

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.

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!

Reviewing the Telecom 101 Table of Contents, you’ll find that many chapters are like self-contained reference books on specific topics; get all of these topics bound in one volume for one low price.

Compare this to hunting down and paying for multiple books by different authors that may or may not cover what you need to know- and you’ll agree this is a very attractive deal.

Telecom 101 is an economical and convenient way to self-study… these are the materials to an instructor-led course that costs $1895 to attend.

Written by our top instructor, Eric Coll, M.Eng., Telecom 101 contains decades of knowledge and learning distilled and organized into an invaluable study guide and practical day-to-day reference for non-engineers: career- and productivity-enhancing training… an investment in life-long knowledge that will be repaid many times over.

Tutorial: Network Core Nodes

Section 10.6.4 of Telecom 101: Sixth Edition 2022

A carrier’s network core, colloquially referred to as their backbone, provides high-capacity, high-availability connections, notionally between cities.

The connections can be between Central Offices, wire centers, toll centers, other switching centers, CATV head ends, Mobile Telephone Switching Offices, Internet Exchanges and/or data centers.

Fiber optics is used as the basis of the connections since it can support very high numbers of bits per second. Lower-speed (and lower-cost) circuits are used to provide access to this core to users.

At the end of each fiber that makes up the network core is a router. The router is sometimes called a network node, after the French word for knot. In some cases, the entire building housing this router is called a node.

A knot, because in addition to connecting core fibers to other cities, the many local access fibers to buildings, neighborhoods, cell sites and everything else are also connected to the core at this node.

Figure 121 provides a closer look at the architecture of a core network node.

DWDM (Section 10.4) is used on core fibers to increase the capacity connecting routers in different cities to bit rates measured in the Terabits per second.

A gateway router is placed as a point of traffic control between access circuits on the right and the core router on the left. This gateway router also implements MPLS (Chapter 17), which is used to manage capacity on the network circuits.

Terminating a physical fiber means plugging it into an Optical Ethernet SFP transceiver inserted in a hardware port in a rack-mount device.

Routers are built with a relatively small number of hardware ports between which they can relay packets at line speed. Some of these ports would terminate core fibers, and others terminate connections to aggregation devices for access fibers via that node’s gateway router as illustrated in Figure 121.

Layer 2 switches (Section 15.4) with up to hundreds of Optical Ethernet hardware ports each are used to terminate the access fibers, which can number in the thousands.

Layer 2 switches are also data concentration or aggregation devices, interspersing traffic from all of the access circuits into high-speed streams to feed to the router. Everything works in both directions at the same time.

Layer 2 switches also implement VLANs (Section 15.5), a critical tool for segregating different users on the same access fibers in cooperation with additional Layer 2 switches connected downstream, as described in the next section.

Another Free Preview from Course 2214 MPLS and Carrier Networks

Course 2214 MPLS and Carrier Networks
Lesson 7 TCP/IP over MPLS

Carrier Packet Networks • Technologies • MPLS • MPLS VPNs • SLAs • CoS • Integration & Aggregation

MPLS and Carrier Networks is a comprehensive training course designed to build a solid understanding of carrier packet networks and services, the terminology, technologies, configuration, operation and most importantly, the underlying ideas… in plain English.

In this free online network training course lesson, we’ll trace the flow of a file transfer over an MPLS network, seeing how TCP is used for error recovery, IP is used for addressing the destination, MAC addresses indicate the next device, and MPLS labels implement a virtual circuit for communications within the carrier IP network.

We’ll follow a file download through all the protocols, identifying each step and the equipment that implements it. To conclude, we’ll see how MPLS can be used to move MAC frames instead of the usual IP packets for a service called Virtual Private LAN Service (VPLS), also known as Carrier Ethernet.

This course is available on its own, and is included in the CTNS Certification Package, the CTA Certification Package, the CIPTS Certification Package and the CTSME Certification Package.
