Abstract
A loopback connector system for testing token ring components such as routers or interface assemblies with requiring that the component to be tested be connected into the local area network (LAN). The connector permits the component to be tested to be isolated from the LAN, permitting the integrity of the component to be tested without regard to the integrity of lobe cables or other devices on the ring, and without degrading network performance. The connector system includes two different multi-pin connector types, a DB9 and an RJ45 connector, used to connect into the network, separated by a short two-pair cable. Resistors used to simulate the network loading on the component are connected between appropriate pins, with the resistors being shared between the two types of connectors.
