ISDN status
Information on connection status at the ISDN S
0
connector:
If the ISDN status LED goes off automatically, this does not indicate
an error at the S
0
bus. It is in fact because several ISDN connections
and PBXs switch the S
0
bus into power-saving mode after a certain
period of inactivity. When needed, the S
0
bus automatically reactiva-
tes and the ISDN status LED illuminates in green.
