1. Introduction

   The ANSI High-Performance Parallel Interface (HIPPI) is a dual
   simplex data channel.   HIPPI can send and receive data
   simultaneously at 800 or 1600 megabits per second. Between 1987 and
   1997, the ANSI X3T11.1 HIPPI working group (now known as NCITS T11.1)
   Standardized five documents that bear on the use of HIPPI as a
   network interface.  They cover the physical and electrical
   specification (HIPPI-PH [1]), the framing of a stream of bytes
   (HIPPI-FP [2]), encapsulation of IEEE 802.2 LLC (HIPPI-LE [3]), the
   behavior of a physical layer switch (HIPPI-SC [4]) and the physical-
   level and optical specification (HIPPI-Serial [5]).  HIPPI-LE also
   implies the encapsulation of Internet Protocol[5].  The reader should
   be familiar with the ANSI HIPPI documents. Approved ANSI NCITS
