  1. NEC Pre-SPIRITS ICW Implementation NEC Implementation for ICW Service (NEC Contribution on pre-SPIRITS ICW Implementation) (../internet-drafts/draft-ago-spirits-icw-00.txt) NEC

  2. NEC Pre-SPIRITS ICW DRAFT A contribution to the future Informational RFC planned by the SPIRITS WG and follows the suggested outline An architecture that includes a SPIRITS server and a SPIRITS client, which in association with the PSTN and the IN offer the ICW service SCP - SPIRITS Server Interface is as defined in RFC 768, RFC 1122. The remote operation messages are based on ITU-T Q.1228 with some NEC proprietary extensions. SPRITS server - Client interface is via a secured reliable Hybrid Datagram Session Protocol (SRHDSP). NEC

  5. CONCLUSION • The architecture described in this ID includes the building blocks - SPIRITS Server, SPIRITS Client and the PSTN/IN requesting system and an initial service (ICW) planned for the "Services in the PSTN/IN Requesting InTernet Service (SPIRITS)". • NEC offers to participate in SPIRITS future informational RFC development.
