Reference Guide for the Model RT210/RT211 ISDN Routers

Troubleshooting 5-7

• Line conﬁguration

To make sure that your line conﬁguration is correct:

a. Check to see whether the LED on the router remains steady or only blinks once and

then remains steady for several seconds. A steady LED or an LED that blinks once

and then remains steady indicates improper line conﬁguration.

b. Check the values you have entered for Switch Type, Directory Number, and SPIDs.

c. If you are using the RT210, make sure that the power for the NT1 is turned on before

the router.

• Call Proﬁle

To make sure your call proﬁle is correct:

a. Check the LED on the router. If the LED blinks for less than 10 seconds and then

lights solid, it indicates that the line was dropped or refused by the remote router.

b. Check the values you have entered for Router Name, PPP Proﬁle, and Outgoing

Password.

• Network Conﬁguration

To make sure the network is conﬁgured correctly:

a. Check to see whether the LED blinks.

If the LED does not blink, you might have a bad network conﬁguration.

b. Check to see that the TCP/IP setup on your PC is correct.

The TCP/IP setup must have the IP address of your router set as the gateway.

c. Check to see that the Conﬁgure IP Routes Menu of the built-in interface has a static

route to the remote router.
