Installation
Multiply assigned RJ45 sockets are colour-coded in blue.
One call charge module can be fitted to each FXO card if required (see Fitting call charge modules).
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.
Note:
Circuit type as per EN/IEC 60950: TNV-3
Note:
• In admissibly high temperatures can occur on the FXO card when connecting to local exchanges
generating a very high loop current (up to 90mA). If so, the PCB temperature monitoring
deactivates the FXO ports in groups of 4 ports. If the temperature then drops, the FXO ports are
automatically reactivated group by group. This behaviour can occur particularly when the ambient
temperature is higher than normal and/or with a system with maximum configuration. Normally local
exchanges produce a loop current of approx. 25 mA, which does not cause any restrictions.
