was an implementation of layers 3 to 6 of the [[OSI reference model|OSI model]].  While the ISODE implementation could be configured to use one of several [[X.25]] (CONS) or connectionless lower layer protocols, many ISODE deployments were based on RFC1006,<ref>{{cite web|title=RFC1006|date=May 1987 |url=http://tools.ietf.org/html/rfc1006|publisher=IETF}}</ref>  the implementation of OSI transport protocol TP0 as a layer atop [[Transmission Control Protocol|TCP]], in order to use IP-based networks which were becoming increasingly common.
The stack also implemented an [[Abstract Syntax Notation One|ASN.1]] compiler.
