Connection possibilities for FXS terminal interfaces
Tip
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 FXS lines via
the EFOP emergency fan-out panel. In the event of a power failure the
EFOP switches the connected analogue phones automatically and
directly over to the analogue FXO exchange lines (see
"Emergency fan-
out-panel (EFOP)", page 131
).
