The Netscalibur comes with a Virtual LEDs program to help
you diagnose your ISDN hardware and ISDN lines. The setup
program will place the diagnostic tool in the startup group for
easy access. This diagnostic program enables you to verify that
the Netscalibur's ISDN is functioning properly by checking the
ISDN signaling layer lights. If all three signaling layer lights turn
green, it means that the ISDN driver is loaded properly and the
ISDN phone line is synchronized. Occasionally, one of the L3
lights will take longer turning green then the other lights. It may
take up 30 seconds for the line to synchronized with the
telephone company.
For everyday usage, you will find the following information
useful.

L1,L2, and L3 lights turn green color:

loaded successfully. Normally, this is a good indication that the
Netscalibur card, cable, and the ISDN lines are functioning
properly. However, it does not guarantee that the SPID and
phone numbers are entered correctly.
