Function
Interface modules (a send IM and a receive IM) are required if one or more expansion racks
(ER) are to be connected to a central rack (CR). This configuration is described in the
Installation manual .

Interface modules must always be used together. The send modules (send IMs) are inserted
in the CR, whilst the corresponding receive modules (receive IMs) are plugged into the series-
connected ER.
