Title: Telecommunication switch with layer-specific processor capable of attaching atomic function message buffer to internal representation of ppl event indication message upon occurrence of predetermined event

Abstract: The present invention is a standardized host-to-switch application program interface (API) for performing call control processing, capable of being customized to meet telecommunications application and network signalling protocol requirements. The universal API comprises one or more generic messages having programmable fields for transmitting commands, status, and data between the host application and the switch. The present invention further comprises a programmable telecommunication switch that provides a user with the ability to define a desired API protocol, either "standard" or custom in nature, for performing any desired switching functions. The present invention includes a protocol development environment which enables a user to define a separate finite state machine for each port provided by the switch. Each finite state machine may be independently defined by combining a series of elementary processing steps, called atomic functions, into primitives, which are in turn combined with states and events to define the desired state machine. Such state machines may include atomic functions configured to generate predetermined messages under predetermined conditions and containing predetermined information. Such state machines may further include the ability to respond to state events that include the receipt of generic API messages configured to provide the state machine with information from the host application.
