<abstract>
<t>
   This document contains the information relevant to the development of
   the inter-networking interfaces underway in the Public Switched
   Telephone Network (PSTN)/Internet Inter-Networking (PINT) Working
   Group. It addresses technologies, architectures, and several (but by
   no means all) existing pre-PINT implementations of the arrangements
   through which Internet applications can request and enrich PSTN
   telecommunications services. The common denominator of the enriched
   services (a.k.a. PINT services) is that they combine the Internet and
   PSTN services in such a way that the Internet is used for non-voice
   interactions, while the voice (and fax) are carried entirely over the
   PSTN. One key observation is that the pre-PINT implementations, being
   developed independently, do not inter-operate. It is a task of the
   PINT Working Group to define the inter-networking interfaces that
   will support inter-operation of the future implementations of PINT
   services.
