PINT Services and Standards Lawrence Conroy Siemens Roke Manor Research [email protected] Sinnreich/lwc 1 Summary What is PINT? Why Simple Services make Sense PINT Status IETF/ITU Relationship PINT Implementations & Timelines SAINT - Putting it all together Futures Sinnreich/lwc 2 What is PINT? PSTN/Internet Interworking Working Group in IETF; Protocol & MIB Way of driving GSTN Services from IP Net High level Requests from IP Net, Execution within GSTN, Reponses back Can re-use existing I.N. systems Sinnreich/lwc 3 Web Server + PINT Client Web Web Client Client Web Server + PINT Client Internet PINT Gateway PINT Gateway Executive System CO/SN Central Office/ To Rest of Own Service Node To Rest of Own Network Network To Other To Other Operators Operators Sinnreich/lwc 4 Why Simple Services make Cents There are 900 Million steam phones Existing GSTN Services get new customers Loose-Coupled : Little change, simple config Can re-use existing I.N. & Billing Systems “Internet-enables” your Central Offices International Callback, Web Directories,... Sinnreich/lwc 5 PINT Status PINT Protocol Based on SIP/SDP Extensions are going to “final call” PINT MIB Based on Application MIB Initial Specification released Discussion continuing Sinnreich/lwc 6 IETF/ITU PINT Relationship PINT Client IETF PINT WG deals with IP Protocol for carrying requests & responses; how the requested services are executed is someone else’s problem PINT/SIP Proxy PINT/SIP PINT Gateway MAGIC Sinnreich/lwc 7 ITU/IETF Relationship ITU SG11 deals with Architecture and Protocols between GSTN Components Liaison to PINT WG agreed at March ITU SG11 meeting Agreement that PINT works with Existing I.N. Recommendations A PINT Gateway is a (very) clever terminal Sinnreich/lwc 8 PINT Implementations & Timelines PINT Products from Siemens & Lucent Both companies demonstrated at CeBIT Siemens’ EWSD supports R2D services - now ; INXpress v.7 VDI development in progress due Q1’01 Lucent’s “Telecommand” supports R2D and R2F services - now Other implementations in progress Sinnreich/lwc 9 SAINT - Putting it all together PINT - Requests from IP, Action in GSTN, Status to IP PIN/TNIP - Requests from GSTN, Action in IP Net, Status to GSTN SAINT - Combination services - PSTN triggers IP Net and this then triggers PSTN (or the other way) Sinnreich/lwc 10 Internet Call Waiting - SAINT Register 200 200 INVITE ACK INVITE ACK 200 CO/SN Sinnreich/lwc 11 A Glass Darkly... PINT - Extension of Services and Protocol Features, Management PIN/TNIP - Service Requirements and formally starting WG ITU - CS4 - Parlay, PINT, and all that Implementations - Expanded services and creation tools, interoperability tests The little matter of Security...
