Problems With the ISDN Line

The ISDN initialization failed

This problem occurs when you attempt to save the parameters
entered in menu 2, but receive the message 'Save successful, but

DI-300M and to the wall outlet (to the telephone company).
3. If the code is 2, this indicates an SPID error. Verify the
SPID(s) that you have entered in menu 2. If these are correct,
try to initialize again from menu 24.4.3.

SPID(s) in menu 2. If these are correct, you may also need to
