        Title           : TDM Circuit Emulation Service over Packet Switched 
                          Network (CESoPSN)

This document describes a method for encapsulating unstructured  (T1, 
E1, T3, E3) and structured (n*DS0) TDM signals as pseudo-wires over 
packet-switching networks (PSN). In this regard, it complements similar 
work for SONET/SDH. 
 
Proposed PW encapsulation uses RTP for clock recovery and leverages 
RTP-based mixing capabilities for application state signaling between 
Customer Edge (CE) devices.

NOTE:   The mail server at ietf.org 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.

implementation to automatically retrieve the ASCII version of the
