Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. This document describes the use of PPP over Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) circuits.

1. Introduction

PPP was designed as a standard method of communicating over

point-to-point links. Initial deployment has been over short local

lines, leased lines, and plain-old-telephone-service (POTS) using

modems. As new packet services and higher speed lines are introduced,

PPP is easily deployed in these environments as well.

This specification is primarily concerned with the use of the PPP

encapsulation over SONET/SDH links. Since SONET/SDH is by definition

a point-to-point circuit, PPP is well suited to use over these links.

Real differences between SONET and SDH (other than terminology) are

minor; for the purposes of encapsulation of PPP over SONET/SDH, they

are inconsequential or irrelevant.

For the convenience of the reader, we list the equivalent terms below:

SONET SDH
