Abstract
The device is a subscriber apparatus with one or more modules interconnected by a bi-directional bus which communicates both digital and analog signals. The module perform different telecommunication functions, such as telephone, telefax, etc. Each module includes storage with a module-specific control program. The control unit may control the whole subscriber apparatus. When a new module is connected to the bus, an identification is assigned thereto which further determines the start address for the module-specific control program.
