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

§1Link Numbers Outside the Allowed Range
The authors say TENEX systems were using link numbers beyond the range permitted by the official Host-Host protocol. The RFC does not list the valid range or the specific numbers that caused the problem.
TENEX systems were using connection numbers that the Host-Host protocol did not allow. This notice does not give the valid range.
§2Connection Problems for Other Sites
The out-of-range link usage caused problems for some sites when they attempted to establish connections with TENEX systems. The RFC describes the effect but gives no further technical details about the failures.
Some sites could not establish connections with TENEX systems because the link numbers did not follow the protocol.
§3Request to Follow the Protocol
Jonathan Postel and Chuck Kline urge that all TENEX systems be brought into conformance with the established Host-Host protocol. This short notice does not specify a correction procedure or report whether systems were changed.
The authors ask the people responsible for TENEX systems to make them follow the Host-Host protocol. The notice does not say what changes were made afterward.
