4. 6. 2 Indirect cabling
There are two possibilities for connecting the communication server indirectly to
the telephone network and terminal-side cabling:
• Connection via main distribution board
• Connection to a universal building cable installation (UBC)
4. 6. 2. 1 Connection via main distribution board
Fig. 29 Connection via main distribution board
The interface sockets on the front panel and on the fan-out-panel (FOP) where ap-
plicable are connected with the (main) distribution frame or the patch panels using
either patch cables or prefabricated system cables (see "Equipment Overview",
page 279).
Prefabricated system cable 4 x RJ45
With terminal cards with 16 or more interfaces some or all of the RJ45 sockets are
assigned four-fold on the front panel of the Aastra 470. With this cable they can be
connected without the use of a fan-out-panel (FOP). The cable is 6 m long and at
one extremity has four RJ45 connectors on which all the pins are wired.
