This is a new course being tested before incorporation in a Certification Package. Feel free to take this course at the "testing" price, and please let us know of any typos or glitches you might find.
In this course, you’ll build a solid base of knowledge in fundamental telecommunication concepts, beginning with a model for understanding circuits and information communication, client-server and peer-to-peer communication, analog vs. digital and how bits are represented by pulses, what modems do, and multiplexing: different methods of sharing circuits, and finishing with an analogy illustrating the idea behind transmitting large files in small packets.
Course Lessons
1. Communication Circuit Model
2. Terminals, Clients, Servers and Peers
3. Analog and Digital
4. Bits in Frequency Channels: Modems and Modulation
5. Frequency-Division Multiplexing
6. Time-Division Multiplexing (TDM)
7. Statistical Time Division Multiplexing
8. Packet Network: The Postal Service
Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we’ll cut through the jargon to demystify telecom fundamentals, explaining the jargon and buzzwords, the underlying ideas, and how it all works together… in plain English.
A course completion certificate is awarded upon passing the course exam.
Course Outline
1. Communication Circuit Model
DTE-DCE circuit model: coding then representing information on circuits
2. Terminals, Clients, Servers and Peers
Communication between different types of terminal equipment
3. Analog and Digital
The problem with analog transmission; representing 1s and 0s with pulses
4. Bits in Frequency Channels: Modems and Modulation
How modems represent 1s and 0s using ASK, FSK, PSK, QPSK and QAM
5. Frequency-Division Multiplexing
Sharing a circuit by implementing many small frequency channels
6. Time-Division Multiplexing (TDM)
Sharing a circuit by taking turns in time in a strict order
7. Statistical Time Division Multiplexing
Sharing a circuit on demand with packets
8. Packet Network: The Postal Service
The very fundamental idea of how large files are tranferred in small packets using an analogy of the Postal Service

In this comprehensive course, you’ll build a solid base of knowledge in networking fundamentals. We'll begin with serial and parallel point-to-point circuits, then identify the need for link addressing and access control on circuits with multiple stations, LANs and how the stations on a LAN form a broadcast domain. We'll understand the need for framing and error control to transmit data, and how this is implemented with MAC frames and MAC addresses. Then we'll define a network, and how it is implemented with WAN circuits, routers and IP network addresses as the basis of routing decisions. Then we'll understand how carrier packet networks are used to implement WAN circuits, the relationship between packets and frames, the IP address on the packet and how the MAC address changes as the packet is forwarded across a network. We'll finish with an overview of IPv4 and IPv6 packet formats, the need for a transport protocol and how TCP is used for reliability, and UDP is used for streaming, and what port numbers are and how they are used. The course is completed with an introduction to MPLS, the traffic management system used on the core of big networks.

Course Outline
1. Point-to-Point Circuits: Serial and Parallel
How serial is a type of Time-Division Multiplexing, and implemented in parallel to increase capacity.
2. Multidrop Circuits: Point to Multipoint
Master-slave or "unbalanced" communication links, and the need for link addressing and access control when there are multiple stations on a circuit.
3. LANs and Broadcast Domains
"Balanced" communication links, where all stations are equal. How the computers connected by a LAN form a broadcast domain. How serial is a type of Time-Division Multiplexing, and implemented in parallel to increase capacity.
4. Framing and Error Control Requirements
Why framing and error control are needed to transmit data. We'll briefly discuss the old "asynchronous" start-stop-parity method, what asynchronous really means, and areas for improvement.
5. Frames & MAC Addresses
The method used for framing, link addressing and error control on the customer premise LAN, on the access circuit, and in the carrier network core.
6. Networks, Routers and IP Addresses
The definition of a network: the need to make route decisions, by a router, using IP addresses as the basis of making route decisions. Identification of WAN services as the expensive part of the story.
7. Carrier Packet Network Services
Using a carrier packet network, whether it is the Internet or carefully-controlled carrier circuits, as the most cost-effective and flexible way of implementing WAN circuits.
8. Packets vs. Frames
How packets are carried in frames. The relationship between the MAC address on a frame and the IP address on a packet. Does one packet fit exactly inside one frame? What protocol segments a big file into small packets?
9. IP Address vs. MAC Address: SFO-NYC via AT&T
Understanding the IP address on a packet vs. the MAC address on a frame, and how it changes from one hop to the next across a network.
10. IP Packets
An overview of the structure of IP packets, and both the IPv4 and IPv6 packet headers.
11. TCP, UDP and Port Numbers
Why a transport protocol is required for communication across an unreliable IP packet network. How TCP works, and why UDP is used for live phone calls. What port numbers are and how they are used.
12. MPLS Labels
A brief introduction to MPLS, and how it is used to label packets as belonging to a traffic class for management of traffic in the network core.
