This document defines a protocol for backhauling of Integrated
Services Digital Network (ISDN) Q.921 User messages over IP using the
Stream Control Transmission Protocol (SCTP).  This protocol would be
used between a Signaling Gateway (SG) and Media Gateway Controller
(MGC).  It is assumed that the SG receives ISDN signaling over a
standard ISDN interface.

This document obsoletes RFC 3057.

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.

This announcement is sent to the IETF list and the RFC-DIST list.
