Important notes for the UP0-connection
• You can connect a further eight ISDN devices with an S0 port at the S0 jack of the telephone. Howe-
ver, if these terminal devices are powered by the elmeg CS 290-U system telephone, then two devices
only may be connected.
• The ISDN connection constellation for down-circuit terminal devices on the system telephone must
be star-shaped (please use the ISDN distributor).
• The maximum line distance between the elmeg CS 290-U and any downstream ISDN terminal devi-
ces may not exceed 100 meters.
• Terminating resistors may not be connected.
