Fan-Out Panel Fop - Mitel 470 System Manual

Installation
FXS mode: General bell
One FXS interface per communication server can be configured for the connection of a
general bell. It is possible to use commercial auxiliary bells designed for connection in
parallel to analogue terminals as a general bell. However the impedance of the con-
nected general bell (or total impedance in the case of several devices connected in
parallel) must not fall below 1 kΩ. The ringing voltage is 48 VAC. A 48 V relay must be
interposed when connecting a large number of auxiliary bells.

Fan-out panel FOP

All interface cards with 16 or more interfaces have four-fold assigned RJ45 sockets.
With the fan-out panel FOP a total of 10 four-fold assigned RJ45 sockets can be split to
individual RJ45 sockets.
The fan-out panel (FOP) takes up the space of one height unit in a rack and can be fit-
ted directly above or below the communication server.

Fan-out panels can also be offset, e.g. as floor distributors.
Connection
The diagram below shows the connection of an interface card 16DSI with terminals.
This card has 2 four-fold assigned RJ45 sockets. The 8 individually assigned RJ45
sockets are connected directly while the 2 four-fold assigned sockets are looped via
the front panel of the fan-out-panel connector (FOP) strip using 2 patch cables.
