Introduction to Transmission Systems, POTS, ISDN, DLC, OCx Systems and Technologies Book

Transmission systems interconnect communication devices by guiding signal energy in a particular direction or directions through a transmission medium such as copper, air, or glass. This chapter excerpted from Introduction to Telecom Systems describes the types of transmission systems used in modern telecommunications networks. This includes multiplexed signals on twisted wire pairs, coax cable, fiberoptic cable and radio. Several technical aspects of transmission systems are covered including: analog transmission, digital transmission, and transmission medium limitations. Many facets of Transmission Systems are also explained, including: plain old telephone service (POTS), digital signal level (DSx), integrated services digital network (ISDN), digital subscriber line (DSL), optical carrier (OCx), ISDN digital subscriber line (IDSL), integrated digital loop carrier (IDLC), in-band signaling, out-of-band signaling, virtual circuits, and repeaters.Read More
