In the following, these analogue phones are referred to as emergency phones. In
normal operation emergency phones act like ordinary internal phones. Only
phones capable of operating without their own power supply are suitable as emer-
gency phones. Both DTMF and pulse dialling phones are supported. It is recom-
mended to identify emergency phones as such.
The fan-out panel EFOP takes up the space of one height unit in a rack and can be
fitted directly above or below the communication server.
Detailed Description
The block diagram below illustrates how the EFOP fan-out-panel operates. The
lines are switched over by relays. When relays are in a de-energised idle state, the
emergency phones are connected directly with the analogue exchange lines
(PSTN). For each port the relay switching status is indicated by an LED.
