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. 43 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 156) or with 8-fold assigned connecting
cables (see e.g. "Prefabricated system cable 4 x RJ45", page 115).
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 "Emergency
fan-out-panel (EFOP)", page 160).
One call charge module can be fitted to each FXO card if required (see "Fitting call
charge modules", page 112).
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
– Inadmissible 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
