Connecting an ISDN Line to Cisco 802 and Cisco 804 Routers

To connect an ISDN line to Cisco 802 and Cisco 804 routers, follow the steps in Figure 2-5.

Warning Network hazardous voltages are present in the ISDN cable. If you detach the ISDN 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 ISDN 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 ISDN U port on the router. Do not connect the cable to a yellow Ethernet port. This will damage your router.

Caution The Cisco 800 series 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 800 series router stops communicating with other devices.
