restore the factory defaults otherwise it will use the stored settings.
If a setting has been changed and the Primary to Basic Rate ISDN Multiplexer ceases to
operate, powering up the Primary to Basic Rate ISDN Multiplexer, while holding down <ctrl-
c> for the first 20 seconds will restore a working configuration to the Primary to Basic Rate
ISDN Multiplexer.
