Clearspan Architecture
Typically, Clearspan is centrally deployed and remotely managed. As such, the architecture is
ideal for premises-based, private network and hosted data centers. The following figure shows a
high-level architecture for Clearspan.
Figure 1. High-Level Clearspan Architecture.
A Clearspan ‘Core’ is an important term used to define a group of equipment and services that
provide call control, security, media resources and web-based management functions. A basic
deployment has two fully redundant cores that are typically deployed in geographically dispersed
data centers. Then one or more networks are used to provide access to users.
A Clearspan ‘Campus’ is the other important term used. A Campus may be co-located with the
cores (premises model) or remote (managed services or hosted model). Tremendous flexibility
allows mixing the models to match exact customer requirements. A Campus may be a large or
small population of users.
Cores and Campuses will be described in further detail later in this document.
