Course Description:
This course provides a functional description of telecommunications networks. The Public Switched Telephone Network (PSTN) is introduced and its three basic functions - Access, Transport and Switching are defined. SS7 and Q.931 signaling, digital transmission systems, Local Exchange and Tandem switches, and PBX are among the topics discussed. Data Communications networks are studied in relationship to the infrastructure and services available from the PSTN. WAN technologies are introduced - including Circuit Switched - leased line and ISDN, and Packet Switched - Frame Relay and ATM. The course includes an introduction to Next-Generation Networks, the evolution of broadband technologies and the use of IP and ATM technologies in the provision of integrated voice, data and multimedia over multi-service networks.
