4. 7. 2. 3 FXO network interfaces
Fitting the corresponding interface cards means that FXO network 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 FXO network interfaces
One call charge module can be fitted to each FXO card if required (see "Fitting call
charge modules", page 92 ).
In a direct connection the RJ45 connector is connected directly to the trunk cable
using a crimp clip.
With an indirection connection you need to observe the cable requirements.
