Initializing ISDN and Performing the Loopback Test

If the Perform ISDN Initialization/Loopback Test box is checked, FirstGear initializes the router
ISDN line and performs a loopback test when you click on Next.
During the ISDN Initialization and Loopback Test, the following events occur:
• FirstGear sends the configuration information to the router and resets the router's ISDN port.
• The D LED on the front panel lights.
• FirstGear instructs the router to place a loopback call, in which B channel 1 places a call to B
channel 2.
• The two B channel LEDs light together for a few seconds. If the call completes successfully,
FirstGear proceeds to the ISP Information screen.
