Fan-Out Panel Fop - Mitel Aastra 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 con-
nection in parallel to analogue terminals as a general bell. However the impedance
of the connected general bell (or total impedance in the case of several devices
connected in parallel) must not fall below 1 k. 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
fitted directly above or below the communication server.
