Terminal Endpoint Identifier Query Request Number Change
RFC 5133, “Terminal Endpoint Identifier Query Request Number Change”, is a Proposed Standard document published in December 2007 by M. Tuexen, K. Morneault. It updates RFC 4233. The canonical text is published by the RFC Editor.
Abstract
The Integrated Services Digital Network (ISDN) Q.921-User Adaptation Layer (IUA) Protocol, described in RFC 4233, defines the message type of Terminal Endpoint Identifier (TEI) Query Request messages as 5. However, this number is already being used by the Digital Private Network Signaling System (DPNSS)/Digital Access Signaling System 2 (DASS 2) Extensions (DUA) to the IUA Protocol described in RFC 4129. This document updates RFC 4233 such that the message type of TEI Query Request messages is 8. [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.
