 A Revised Internet-Draft is available from the on-line Internet-Drafts 
 directories. This draft is a work item of the Internetworking Over NBMA 
 Working Group of the IETF.                                                

       Title     : ATM Signalling Support for IP over ATM - 
                   UNI Signalling 4.0 Update 
       Author(s) : M. Maher
       Filename  : draft-ietf-ion-sig-uni4.0-04.txt
       Pages     : 26
       Date      : 05/29/1997

This memo describes how to efficiently use the ATM call control signalling 
procedures defined in UNI Signalling 4.0 [SIG40] to support IP over ATM 
environments as described in RFC 1577 [LAUB94] and in [LUC97]. Among the 
new features found in UNI Signalling 4.0 are Available Bit Rate signalling 
and traffic parameter negotiation.  This draft highlights the features of 
UNI Signalling 4.0 that provide IP entities capabilities for requesting ATM
service in sites with SVC support, whether it is private ATM or publicly 
provisioned ATM, in which case the SVC support is probably configured 
inside PVPs.                                                    

This document is only relevant to IP when used as the well known 
"best effort" connectionless service. In particular, this means that 
this document does not pertain to IP in the presence of implemented 
IP Integrated Services.  The topic of IP with Integrated Services 
over ATM will be handled by a different specification or set of 
specifications being worked on in the ISSLL WG.       
                                    
This specification is follow-on to RFC 1755, "ATM Signaling Support 
for IP over ATM", which is based on UNI 3.1 signalling [UNI95].                                       
Readers are assumed to be familiar with RFC 1755.

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-ietf-ion-sig-uni4.0-04.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
