The Point-to-Point Protocol (PPP) in RFC-1661 [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links, and RFCs 1662 [2] and 1619 [3] provide a means to carry PPP over Synchronous Optical Network (SONET) [5] and Synchronous Digital Hierarchy (SDH) [6] circuits. PPP over Simple Data Link (SDL) using SONET/SDH with ATM-like framing (PPPEXT WG work in Progress) extended these standards to include a new encapsulation for PPP called Simple Data Link (SDL) [8]. This document extends the use of SDL over raw lightwave channels without an intervening SONET/SDH layer, which are also referred to as 'dark fiber' or Packet-over-Lightwave' (POL) links
