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.
This document is a product of the Signaling Transport Working Group of
the IETF.
This is now a Proposed Standard Protocol.
This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol. Distribution
of this memo is unlimited.
