Connect the cable DB-60 connector to the SERIAL Ø port on the Cisco 1601.
Connect the other end of the cable to one of the following devices:
•
Asynchronous modem that you provide if connecting to an analog telephone
line.
•
Synchronous modem, DSU/CSU, or other data circuit-terminating
equipment (DCE) that you provide if connecting to a digital WAN line.
Check the RDY LED on the rear panel. It lights when the router is correctly
connected to the modem or DSU/CSU. If the RDY LED is not on, refer to the
"Troubleshooting" appendix later in this guide.
