The active star couplers form the branching points on a 10 Mbps network using the
CSMA/CD access protocol complying with IEEE 802.3. The modular concept
allows a flexible network structure with various transmission media such as triaxial
cable (727-0 bus cable), Industrial Twisted Pair cable, fiber-optic cable (FO) or
drop cables (727-1).
The star coupler has the following properties and functions:
S Strong construction with die-cast aluminum housing
S Can be used as a desktop unit or in a 19” cabinet
S Interface cards available for various transmission media and
applications
S Easy servicing by replacing interface cards during operation
S Monitoring with HSSM 2 signaling card
S SNMP management capability with MIKE management card
S Also available as 24 V version
S Redundancy concepts possible with ring topology using fiber-optic cable
