ATIS T1.TR.55-1998

This Technical Report addresses the reliability and survivability aspects of the interactions between the Internet and the Public Telecommunications Network (PTN). It examines the general architectures of both networks and the interfaces between them. This document offers suggestions for meeting reliability challenges posed by changing network traffic characteristics. Two major categories of solutions are introduced: network engineering and network architecture. Within these categories, alternatives may be selected depending on the operator's local circumstances.
