Englishelmeg CS290 at the ISDN portConnect the ISDN-cord (1) to the S0-jack asshown in figure 2. Ensure that the longer ISDNconnector is plugged into the ISDN jack and theshorter ISDN connector into the ISDN socket onthe telephone. Then lay the ISDN cord in the cordgroove (2) and lock it below the two cord retainers(3).Figure 2elmeg CS 290-U at the UP0-portConnect the ISDN-cord (1) to the UP0jack asshown in figure 1. Ensure that the longer ISDNconnector is plugged into the ISDN jack and theshorter ISDN connector into the ISDN socket onthe telephone. Then lay the ISDN cord in the cordgroove (2) and lock it below the two cord retainers(3). Figure 1 shows a downstream ISDN-telephoneconnected to the S0--port of the elmeg 290-U.Figure 1CS290-U phones may not be connected through the S0 jack to the ISDN connection.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. However,if these terminal devices are powered by the elmeg CS 290-U system telephone, then two devicesonly may be connected.• The ISDN connection constellation for down-circuit terminal devices on the system telephone mustbe star-shaped (please use the ISDN distributor).• The maximum line distance between the elmeg CS 290-U and any downstream ISDN terminal devicesmay not exceed 100 meters.• Terminating resistors may not be connected.5
