Multiple systems can be implemented, viewed, and managed as if they were one system.
This type of management is known as subtending. To subtend, connect and configure Avidia
systems in one of two ways: a star configuration or a daisy chain configuration.
In either implementation, multiple systems connect to one system that aggregates the
transmission of all the attached systems and provides one network uplink. The aggregating
system is known as the subtending or source system and each of the systems connected to it are
known as the subtended or destination systems.
See the figure below for a representation of both daisy chained and star configured systems. In
the figure, the subtending systems in each configuration aggregate the transmissions of the
subtended systems and provide a network uplink via OC3 to the ATM Switch.
