Core Architecture
The Clearspan Cores provide all of the Unified Communication (UC) features and functions. The
following figure shows the conceptual view of the Clearspan Cores. At the center resides the
BroadWorks server complex
– a multi-tenant architecture deployed in the largest carriers in the
world. Wrapped around the BroadWorks server complex is a layer of advanced security and
interconnect. The outer layer adds all of the advanced UC applications.

The Core software is realized on off-the-shelf servers as shown in Figure 3. The software-only
solution runs on a combination of IBM BladeCenter chassis and discreet servers, using either AC
or DC power options.
