Back-to-Back Test Cables

Two 5-meter, back-to-back, synchronous test cables are available from HP. These cables allow you to connect any HP router having a (62-pin) synchronous WAN port to another HP router (or an HP Remote Bridge) having the same port type, without using a modem eliminator, for up to 60 meters (200 feet). These cables use the RS-422 signal level. Use the test cables for demonstrations, instruction, or testing the router.

The two test cables available are:
