ABSTRACT:
The present invention provides a client station and method for controlling a telecommunications system, the telecommunications system including a central station and a server station. The server station is arranged to maintain an object model thereon representing the central station, and is connectable to the central station to send control signals to the central station in accordance with the object model. The client station comprises a communications manager for establishing first and second interfaces with the server station to enable communication between the client station and the server station, thereby to manage the object model maintained on the server. The client station has a memory for storing a portion of the object model, and a processor for processing commands received by the client station via the first interface from a queue maintained on the server station. Further, there is provided a retrieval means, responsive to a command requiring an operation to be performed on an object not currently in the portion of the object model stored in the memory, for retrieving from the server station via the second interface said object for inclusion in the portion of the object model stored in the memory, during which time no further commands are processed by the processor.
