DIGITAL COMMUNICATIONS SYSTEM FOR RESIDENTIAL AND CUSTODIAL-CARE ENVIRONMENTS, OFFICE AND THE LIKE
First Claim
1. Digital communications system for residential, custodial-care environments, office and the like destined to integrate different communications services within a single network, such as voice, video, alarm control, entryphone and Internet traffic, as well as heating and air-conditioning system control services and the activation of different electrical equipments, structured through a set of interconnected modules or terminals forming a network characterized in that the terminals (1), (1′
- ), . . . , (1n) are interconnected through data transmission cables, such as UTP cables (4) for differential transmission, with a read bus (2) and a write bus (3), wherein each module will have at least one PLD card (7) containing a programmable logic device for the management of a series of cards associated to the said card, materialising them in a main card (8) with two A/D, D/A audio converters (14), (15), as well as the corresponding circuits and connectors (5) for the interconnection of terminals or modules with the aforesaid physical means (UTP, telephone cable, optical fibre, wireless, electrical network), and a user interface card (9) that includes a display (19) and a keyboard (20), and a series of piezoelectric buzzers (21) that allow the user to configure the different system options, receiving information about each situation and condition, in addition optionally including one or various expansion cards (11-11′
) which can be associated to named PLD card (7) for the input or output of audio, video, Internet, telephone line or entryphone line signals, as well as a remote control and alarm card (10) used for the activation of external loads, alarms and to gather signals coming from sensors.

Abstract
The system is based on the arrangement of a plurality of terminals (1), (I′) . . . (In), which are interconnected with one another to form a digital network by means of two databuses, one write and one read, by means of differential transmission, with a hybrid connection topology based inter alia on UTP-type cables (4). Each terminal is constituted by a DLP-type card (7), which contains a programmable logic device for the management of a series of cards associated with the card (7), said cards being a main card (8) and a user-interface card (9), which enable the user to configure the various system options, it being possible, also, to incorporate one or more extension cards (H-H′) for the input and output of audio/video signals, the Internet, a telephone line or an automatic-door-entry line, and also a remote-control and alarm card (10) for activating external loads, activating alarms and receiving signals originating from sensors.
