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.
