es:
3.3 UPnP Settings
The Universal Plug-and-Play (UPnP) service included in
your FRITZ!Box provides status information about the
FRITZ!Box to all connected computers. Programs with
UPnP support on these computers can receive this infor-
mation and use them to display the status of the
FRITZ!Box (e.g., DSL synchronization, connection status,
data transmission). UPnP service thus allows you to moni-
tor your FRITZ!Box from a connected computer.
The FRITZ!DSL software receives status information from
the FRITZ!Box via UPnP.
