A method and apparatus for inserting a computer network protocol analyzer into a Token Ring network. Commercial integrated circuits are used to initiate a standard protocol test and synchronization sequence and to actuate an insertion relay in a network coupling unit. After actuation of the insertion relay, incoming network data is switched onto outgoing network data lines, bypassing the commercial protocol circuitry. As a result, the analyzer can be inserted into a Token Ring even when there are network problems which would prohibit insertion under normal protocol.
