Abstract
This document describes the SPIRITS protocol requirements, based on
the architecture presented in RFC 3136. (SPIRITS stands for "Service
in the PSTN/IN Requesting InTernet Service".) The purpose of the
protocol is to support services that originate in the Public Switched
Telephone Network (PSTN) and necessitate the interactions between the
PSTN and the Internet. Similarly, such services are called SPIRITS
services. (Internet Call Waiting, Internet Caller-ID Delivery, and
Internet Call Forwarding are examples of SPIRIT services, but the
protocol is to define the building blocks from which many other
services can be built.) On the PSTN side, the SPIRITS services are
initiated from the Intelligent Network (IN) entities; the earlier
IETF work on the PSTN/Internet Interworking (PINT) resulted in the
protocol (RFC 2848) in support of the services initiated the other
way around--from the Internet to PSTN.
To this end, this document lists general requirements for the SPIRITS
protocol as well as those pertinent to IN, Wireless IN, and PINT
building blocks. The document also presents the SPIRITS WG consensus
on the choice of the SPIRITS signaling protocol.
