Introduction Total views (540)  
Communication is a process of "exchange'' or "transfer'' of information between two or more entities (persons). Telecommunication can be considered as communication over a long distance. On the other hand, the definition of telecommunication can be stated as: "A means to communicate over a distance using electrical signals, radio waves or light waves.''

Automatic Exchanges (Electro Mechanical) Total views (549)  
After Reading this chapter you will be able To design a Strowger exchange, understand the working of crossbar exchange and electronic exchange.
Pages: 24
Price: Rs 18   
Crossbar and Electronic Exchanges Total views (544)  
In this chapter, we look at the design of an exchange with latest advancements in technology using crossbar concepts and finally an electronic exchange.
Pages: 20
Price: Rs 15   
Telecommunication Traffic Total views (548)  
To understand the parameters used in the design of a switching system, based on probability of traffic. To derive expressions characterising the blocking probabilities, which indicate the efficiency of the switching networks to handle the traffic.
Pages: 42
Price: Rs 31.5   
Switching Networks Total views (553)  
To increase the usage of trunks connected to lower contacts of a sequential selector through grading. To design a multi-stage networks to reduce the number of crosspoints required. Reduction in crosspoints reduces the cost but introduces the blocking probability. The last topic of the chapter deals with these blocking probability calculations.
Pages: 64
Price: Rs 48   
Time-Division Switching Total views (559)  
To introduce the concept of time division and TDM which resulted in a revolution of communication. Digitising voice signals makes it possible to increase the number of channels carried by the media. Also, digitising voice signals along with digital switching enables the use of digital computers at different stages to utilise the advantages of digital techniques.

Price: Rs 31.5   
Control of Switching Systems Total views (567)  
This chapter deals with some of the control aspects of the switching system, especially of common control and control of electronic exchanges with stored program control employing computer technology. In older systems, control was distributed and embedded in switching delay devices.

Signalling Total views (573)  
Signalling systems are as essential as switching systems and transmission systems. For a multi-link connection, it is necessary to send signals in both directions between caller and originating exchange and between the called subscriber and the terminating exchange and between exchanges.

Networks Total views (589)  
Now a days, electronic digital time-division switching systems have replaced electromechanical analog space division switching systems. If space-division switching is used to interconnect circuits provided over high capacity transmission system, it is necessary to install channelling equipment at each end of every link in order to demultiplex every channel to audio frequencies before switching it ......
