Chapter 10 Troubleshooting the Cisco BTS 10200 Softswitch
Components
Feature Server Architecture
The purpose of the FS is to provide access to features through a well-defined interface. The
Cisco BTS 10200 Softswitch architecture separates FS (which provides feature control) from CA (which
provides call control) with a clear interface, Feature Control Protocol (FCP), defined between them. The
independent architecture (FS separate from the CA) provides support for POTS, Centrex, AIN, 800
service, and other enhanced services from multiple FS. These FSs can be located internally, on the same
machine as the CA, as shown in Figure 10-4. CA-to-FS communication is through FCP. Alternatively,
the FS (for POTS, Centrex, and Tandem) can be located externally, on a separate machine from the CA.
In this case, the CA communicates with both the internal and external FS through FCP.

EMS Architecture
The management functions of the EMS are partitioned along the guidelines described by the
Telecommunications Management Network (TMN) standards. This facilitates future migration to these
standards with minimal impact to the existing architecture. These areas include:
• Billing management
• Traffic management
• Fault management
• Event management
• Queuing and audit management
• Configuration management (status and control)
• Security management
