                         LINK USAGE VIOLATION


  We have noticed that TENEX systems use link numbers outside the
  allowed range.  This is a violation of the official HOST-HOST
  protocol.  This causes problems with some sites when attempting to
  establish connections with TENEX systems.  We urge that this problem
  be corrected by bringing all TENEX systems into conformance with the
  established official protocol
