Abstract

   This document describes an extension to the mapping of Point-to-Point
   Protocol (PPP) into Synchronous Optical NETwork/Synchronous Digital
   Hierarchy (SONET/SDH) to include the use of SONET/SDH SPE/VC virtual
   concatenation and the use of both high order and low order payloads.

1. Introduction

   Current implementations of PPP over SONET/SDH are required to select
   transport structures from the relatively limited number of
   contiguously concatenated signals that are available.
