CAB-OCTAL-ASYNC cables use a 68-pin connector and breakout cable to provide eight RJ45 rolled cable asynchronous ports on each 68-pin connector. You can connect each RJ-45 rolled cable asynchronous port to the console or Aux port of a device. The NM-16A or NM-32A high-density asynchronous network modules available for the Cisco 2600 and 3600 series routers can use this cable. * This is a Cisco compatible cable, it is not a Cisco OEM or Cisco brand product.
