Configurations
The DBS comes in three models, which provide from 40 to 96 ports. Up to
two systems can be combined to increase port capacity up to 192 ports (DBS
96 + DBS 96).
In addition to dedicated trunk and extension slots, each system includes one
expansion slot (labeled EC/TRK) that can be used for either trunks or
extensions. The following table shows port capacities for individual systems
and for different combinations of systems.
