4. 6 Connecting the communication server
There are two possibilities for connection to the telephone network and the termi-
nal-side cabling:
• Direct connection
• Indirect cabling via (main) distribution frame and any universal building cable
installation (UBC) (see also Fig. 31 and Fig. 32).
Fig. 28 Direct cabling (left) and indirect cabling (right)
On the front panel all the connections are made using RJ45 connectors.
4. 6. 1 Direct connection
Standard commercial cables are used to connect directly to the telephone net-
work. Details can be found in the Chapter "Network Interfaces", page 121.
On terminal cards with 16 or more interfaces some or all of the RJ45 sockets are
multiply assigned. They can be split into individual RJ45 sockets using patch cables
and the fan-out-panel (see "Fan-out panel FOP", page 156).
