Telecom FundamentalsIn this module, we’ll ensure you have a solid foundation in the fundamental ideas of telecom:The elements of a circuit;Terminals, clients, servers and peers;How bits are represented on fiber with pulses; andHow bits are represented with modems on wireless, cable TV and DSL Then we’ll understand how a circuit’s capacity is shared to carry many users’ traffic on common facilities: Frequency Division Multiplexing, Time Division Multiplexing, and Bandwidth on Demand: efficient sharing, involving packets, routers and overbooking the network core.Telecom Module 2Detailed Outline2 Telecom Fundamentals2.1 Communication Circuit Model…… 2.1.1 Information Theory…… 2.1.2 ITU Model: DTEs and DCEs2.2 Terminals, Clients, Servers and Peers…… 2.2.1 Dumb Terminal and Remote Host…… 2.2.2 Client-Server…… 2.2.3 Peer-to-Peer2.3 Representing Bits on Digital Circuits: Pulses…… 2.3.1 Two-State Transmission Systems…… 2.3.2 Range Limiting Factors…… 2.3.3 Repeaters…… 2.3.4 Comfort Noise Generation2.4 Representing Bits in Frequency Channels: Modems…… 2.4.1 Passband Channels…… 2.4.2 Carrier Frequencies…… 2.4.3 Modulation…… 2.4.4 “Press 1 to Understand How Modems Work”…… 2.4.5 Radio-Frequency Modems…… 2.4.6 CDMA and OFDM…… 2.4.7 ASK, FSK, PSK, QAM and QPSK2.5 Serial and Parallel…… 2.5.1 Serial Ports: USB, LAN, SATA…… 2.5.2 Serial in Parallel for High Bit Rates2.6 Sharing: Frequency-Division Multiplexing…… 2.6.1 Baseband vsFrequency-Shifted…… 2.6.2 Coax, Radio and Fiber…… 2.6.3 Parallel2.7 Sharing: Time-Division Multiplexing…… 2.7.1 Synchronous TDM Channels…… 2.7.2 Trunk Carrier Systems…… 2.7.3 T1, SONET and SDH…… 2.7.4 Other TDM Implementations: PONs, GSM, CAN-BUS2.8 Efficient Sharing: Statistical Time Division Multiplexing…… 2.8.1 Bandwidth on Demand…… 2.8.2 Packet Switching2.9 Overbooking: Reducing User Cost
