FLASHING: The ISDN physical interface is synchronizing.
SOLID: The ISDN physical interface is active.
Note: Flashing stops when synchronization is complete. Continuous flashing indicates an error. Make sure that the line is plugged in properly and that you are using the correct interface (S/T or U). For S/T with an NT1, make sure your ISDN line is terminated (see your ISDN provider for more details).
