What is the maximum system capacity (total and per channel) in Erlangs when providing a 2% blocking probability with 4 channels, with 20 channels, with 40 channels? (b) How many users can be supported with 40 channels at 2% blocking? Assume H = 105 s, λ = 1 call/hour. (c) Using the traffic intensity per channel calculated in part (a), find the grade of service in a lost call delayed system for the case of delays being greater than 20 seconds. Assume that H = 105 s, and determine the GOS for 4 channels, for 20 channels, for 40 channels. (d) Comparing part (a) and part (c), does a lost call delayed system with a 20 second queue perform better than a system that clears blocked calls?

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
