Digital Private Network Signaling System /Digital Access Signaling System 2 Extensions to the IUA Protocol
RFC 4129, “Digital Private Network Signaling System /Digital Access Signaling System 2 Extensions to the IUA Protocol”, is a Proposed Standard document published in September 2005 by R. Mukundan, K. Morneault, N. Mangalpally. The canonical text is published by the RFC Editor.
Abstract
This document defines a mechanism for backhauling Digital Private Network Signaling System 1 (DPNSS 1) and Digital Access Signaling System 2 (DASS 2) messages over IP by extending the ISDN User Adaptation (IUA) Layer Protocol defined in RFC 3057. DPNSS 1, specified in ND1301:2001/03 (formerly BTNR 188), is used to interconnect Private Branch Exchanges (PBX) in a private network. DASS 2, specified in BTNR 190, is used to connect PBXs to the PSTN. This document aims to become an Appendix to IUA and to be the base for a DPNSS 1/DASS 2 User Adaptation (DUA) implementation. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
