Fig. 30 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
page 260).
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.
