It describes the benefits of the new feature, supported platforms, configuration, related documents, and provides command reference information. Figure 1 shows how CAPI connects applications, drivers, and controllers. One application can use one or more controllers.
Several applications can share one or more controllers.
Standardized Network Access CAPI supplies a selection mechanism that supports applications that use protocols at different levels and standardized network access. An abstraction from different protocol variables is performed to provide this support. All connection-related data, such as connection state and display messages, is available to the applications at any time. The Cisco 800 series routers support the following channel protocols. Each B channel can be configured separately to work in either HDLC mode or bit transparent mode.
