            Structure-Agnostic Time Division Multiplexing (TDM)
                            over Packet (SAToP)
  Abstract
     This document describes a pseudowire encapsulation for Time Division
     Multiplexing (TDM) bit-streams (T1, E1, T3, E3) that disregards any
     structure that may be imposed on these streams, in particular the
     structure imposed by the standard TDM framing.

     Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation
              Service over Packet Switched Network (CESoPSN)
  Abstract
     This document describes a method for encapsulating structured (NxDS0)
     Time Division Multiplexed (TDM) signals as pseudowires over packet-
     switching networks (PSNs).  In this regard, it complements similar
     work for structure-agnostic emulation of TDM bit-streams (see RFC
     4553).
