Telephony (/təˈlɛfəni/ tə-LEF-ə-nee) is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone.
Introduction Of Teletraffic Engineering
Introduction Of Teletraffic Engineering Telecommunications traffic engineering , teletraffic engineering , or traffic engineering is the application of traffic engineering theory to telecommunications . Teletraffic engineers use their knowledge of statistics including queuing theory , the nature of traffic, their practical models, their measurements and simulations to make predictions and to plan telecommunication networks such as a telephone network or the Internet . Traffic is defined as a total number of call passing through over a trunk.Channel is defined as a transmission medium.The field was created by the work of A. K. Erlang for circuit-switched networks .A good example of the use of teletraffic theory in practice is in the design and management of a call center . Call centers use teletraffic theory to increase the efficiency of their services and overall profitability through calculating how many operators are really needed at each time of the day.Que
