With the fault mask, it is possible to monitor the port states using the signaling contact. In
addition to interconnecting the switches, it is also possible to connect one or more end
devices to every IE Switch X-400.

3.2.2 Star/tree structure
Functional description
Star/tree structures can be created with IE Switches X-400. The cascading depth and total
span of a network are limited only by the signal propagation times of the communication
connections.
Properties of a star structure
Each IE Switch X-400 communicates over a TP or FO cable with a central switch with which
all other switches are also connected within a star structure. Communication is possible over
the optical or the electrical ports.
