Abstract: This report presents an overview of the 1982 telephone network technology. Many physical facilities constitute the public switched telephone network. Their respective roles in support of voice services and related traffic are reviewed. Essential internal functions, such as accounting, timing, signaling, plus many others, are carried out by cooperative hidden subnetworks that exist within the larger overall public network. Engineering, operation and innovation of these facilities and functions will fall on all sides of exchange area boundaries.
