SmartWare Software Configuration Guide 31 • CS context overview
Introduction
This chapter gives an overview of the circuit-switching (CS) context and associated components, and describes
the tasks involved in its configuration. It describes the steps needed configure voice connectivity, and refers to
other chapters where a configuration topic is explained in more detail. Before reviewing the content in this
chapter, read the configuration concepts as described in chapter 2, “Configuration concepts” on page 44.
The CS context is a high level conceptual entity that is responsible for all aspects of circuit signaling, switching,
and emulation. Besides the CS context itself, the CS entity consists of the following (indicated by the shaded
area enclosed by a dashed line in figure 47):
• The CS interfaces
• ISDN and FXS ports
• Tone-set profiles
• SIP and H.323 gateways
• VoIP profiles
The CS Context is enabled by default.
