PSTN and Internet Internetworking (pint) ---------------------------------------- Charter Last Modified: 28-Aug-97 Current Status: Active Working Group Chair(s): Steve Bellovin Igor Faynberg Transport Area Director(s): Scott Bradner Allyn Romanow Transport Area Advisor: Allyn Romanow Mailing Lists: General Discussion:pint@lists.research.bell-labs.com To Subscribe: pint-request@lists.research.bell-labs.com In Body: subscribe your-email-addres Archive: http://www.bell-labs.com/mailing-lists/pint/ Description of Working Group: The PSTN/Internet Interfaces (PINT) WG addresses connection arrangements through which Internet applications can request and enrich PSTN (Public Switched Telephone Network) telephony services. An example of such services is a Web-based Yellow Pages service with the ability to initiate PSTN calls between customers and suppliers. This working group has six main objectives: * Study architecture and protocols needed to support services in which a user of the Internet requests initiation of a telephone (i.e., PSTN- carried) call to a PSTN terminal (i.e., telephone, FAX machine). The protocols are not to support any form of third-party call control or, for that matter, any type of call control; their role is rather to securely carry call requests to the PSTN. Specific services to be considered initially are Click-to-Dial, Click-to-Fax, Click-to-Fax-Back, and Web access to voice content delivered over the PSTN. * Produce an informational RFC that describes current practices for supporting the services in question. * Based on the existing practice and agreed on improvements, develop a standards track RFC that specifies a Service Support Transfer Protocol (SSTP) between Internet applications or servers and PSTN Intelligent Network Service Nodes (or any other node that implement the Service Control Function). SSTP is an application-specific transport protocol operating over TCP. * Consider security issues relating to prividing functions of this type. In particular understand any threats posed by this technology and resolve them, and any other security issues in the proposed standard. * Based on the existing practice and agreed on improvements, develop a standards track RFC for a relevant MIB (SSTP MIB) to support the service management protocol between Internet applications and the PSTN Service Management System. The SSTP MIB is to conform to SNMP standards. * Consider extensions of the above architecture and protocols to support a wider range of PSTN Intelligent Network (IN) based services. Goals and Milestones: Aug 97 First WG meeting at Munich to discuss 2 submitted drafts and begin work on the informational rfc and on SSTP. Oct 97 Issue first draft of Internet-Draft intended for Informational. Oct 97 Issue first draft of SSTP Internet-Draft Dec 97 Meet at Washington IETF to gain WG consensus on informational draft Jan 98 Submit Internet-Draft to IESG for publication as an Informational RFC Apr 98 Gain WG consensus on SSTP draft May 98 Produce first draft of MIB Internet-Draft Jun 98 Submit SSTP to IESG to be considered as proposed standard Aug 98 Reach consensus on MIB i-d Sep 98 Submit MIB i-d for promotion to proposed RFC status Sep 98 Submit any proposals for future work, to be done by a new WG if accepted Oct 98 Determine if WG is to continue or conclude. Internet-Drafts: No Current Internet-Drafts. Request For Comments: None to date.
