Token Ring Nodes: Physical or Logical Unit Issues



Are Macintosh Token Ring workstations addressed as PUs or LUs?

Nodes are either a physical unit (PU) or a logical unit (LU) in an SNA
environment.

A Macintosh system with a TokenTalk NB Card running MacDFT or MacAPPC is a
downstream PU. A Macintosh system running TokenTalk is neither a PU nor LU --
these terms do not apply unless MacDFT or MacAPPC is being used.
