Programming model overview

NMS TCAP consists of a set of function calls that provide access to the TCAP layer operations, and a set of events that notify the application of incoming messages, network status, and message delivery errors. NMS TCAP also performs the byte ordering translation, where necessary, between application processor (little endian) byte order and network (or big endian) byte order.

NMS TCAP is implemented as a Natural Access service. Natural Access is a development environment for telephony and signaling applications that provides a standard application programming interface for services, such as signaling protocol stacks, independent of the underlying hardware. Understanding the basic Natural Access programming concepts such as services, queues, contexts, and asynchronous events is critical to developing applications that use the TCAP service. Refer to the Natural Access Developer's Reference Manual for more information.
