If your wall jack has an RJ-11 connector, attach RJ-45-to-RJ-11 adapter cable

to red cable, and then connect RJ-11 connector to ISDN wall jack.

Connecting an IDSL Line

Warning Network hazardous voltages are present in the IDSL cable. If you detach the IDSL cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the IDSL port (RJ-45 connector), regardless of when power is turned to standby.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunications line cord.

Caution Always connect the red cable to the red IDSL port on the router. Do not connect the cable to a yellow Ethernet port. This will damage your router.

Caution Cisco 802 IDSL and Cisco 804 IDSL routers do not support the Australian IUT requirement, which specifies that the routers must communicate for 1/2 hour after a power failure. If a power failure occurs, a Cisco 802 IDSL or 804 IDSL router stops communicating with other devices.
