4. 7. 3. 1 Terminal interfaces DSI
Fitting the corresponding interface cards means that DSI terminal interfaces are
available on the RJ45-sockets on the front panel of the cards. The possible RJ45
sockets are highlighted in colour in the figure below.
Fig. 44 Connection possibilities for DSI terminal interfaces
On terminal cards with 16 or more interfaces some or all of the RJ45 sockets are
multiply assigned. The signals can be split again to individual RJ45 sockets using
patch cables and the fan-out panel FOP (see "Fan-out panel FOP", page 156) or with
8-fold assigned connecting cables (see e.g. Prefabricated system cable 4 x RJ45).
Tip
Multiply assigned RJ45 sockets are colour-coded in blue.
