Preface
DC 900-1343D 15
Document Conventions
This document follows the most significant byte first (MSB) and most significant word
first (MSW) conventions for bit-numbering and byte-ordering. In all packet transfers
between the client applications and the ICPs, the ordering of the byte stream is pre-
served. However, DDCMP packed data contains word values that are not byte-
swapped.
The term “Freeway” refers to any of the Freeway server models (for example, Freeway
1100/1150/1200/1300, Freeway 2000/4000, or Freeway 8800), or to the embedded ICP
product (for example, the embedded ICP2432).
Physical “ports” on the ICPs are logically referred to as “links.” However, since port and
link numbers are usually identical (that is, port 0 is the same as link 0), this document
uses the term “link.”
Program code samples are written in the “C” programming language.
