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
On cards with 16 interfaces RJ45 sockets 9 to 16 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
cables (see e.g. "Prefabricated system cable 4 x RJ45", page
Tips
– Multiply assigned RJ45 sockets are colour-coded in blue.
– To be able to make emergency calls even in the event of a mains
power failure, you have the possibility of running up to 8 analogue
FXO exchange lines via the EFOP emergency fan-out panel. In the
event of a power failure the EFOP switches exchange lines automati-
cally and directly over to up to 8 analogue phones (see
fan-out-panel (EFOP)", page
One call charge module can be fitted to each FXO card if required (see
charge modules", page
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.
Notes
– Inadmissibly high temperatures can occur on the FXO card when con-
necting to local exchanges generating a very high loop current (up to
90mA). If so, the PCB temperature monitoring deactivates the FXO
