Abstract:
A craft interface device for maintaining and provisioning operations in a telecommunications network, comprising:a graphical user interface operatively connected to a monitor for displaying thereon structural components of the telecommunications network and lor indicating, on said monitor, operating relationships among said structural components;a port object located in memory and responsive to messages for writing characters for transmission over a data link of said network and for reading characters arriving from said network;a domain modeling framework operatively connected to said graphical user interface for supplying thereto descriptions of said structural components and operating relationships to be displayed; anda communications framework operatively connected to the domain modeling framework for generating and transmitting, in response to user commands detected by the graphical user interface, data requests over said data link and for reading data lines arriving from the network,said communications framework including a parser having an object-oriented state machine operatively coupled to the communications framework for parsing information from an incoming sequence of data lines or events, said parser being operatively connected, via said domain modeling framework, to said graphical user interface for providing information thereto for display, said state machine including a current state object taken from a group of different possible state objects each transformable into at least one of the other state objects in response to an incoming message of a given type.
