Telecommunication Network Switching

Abstract

Network Switching is a vital aspect of telecommunication networks that processes, controls, and manages the flow of information. Mobile switching Centre (MSC) directs traffic around the Network between a mobile station and landline, or between two mobile stations. This chapter presents Soft switch, interfaces, protocol, signalling, call flow, interconnectivity, their properties, and functions of Network switching elements. In practice, the main measures adopted to improve survivability in switched networks such as diversity, the alternative route of traffic, service restoration techniques facilitated by use of spare transmission capacity where patching is possible and an integrated approach is also presented.
