Abstract

In a telephone system serving premises having a plurality of terminals offering subscriber selectable features, an arrangement is described for changing the active features of the terminals according to whether the associated subscribers are on or off the premises. The arrangement comprises a device for generating signals identifying the subscribers and indicating an "in" or "out" status therefor, a memory for storing data indicating the features required by the respective subscribers in their "in" and "out" status, and a device responsive to the signals and the data stored in the memory to select the appropriate features in the telephone system as the subscribers enter and leave the premises.

Claims

1. In a telephone system serving premises having a plurality of terminals each offering subscriber selectable features, and each terminal being associated with a particular subscriber, an arrangement for changing the active features of the terminals according to whether the respective associated subscribers are on or off the premises, comprising input means remote from said terminals and responsive to input from any of said subscribers to generate signals identifying the inputting subscriber and indicating an "in" or "out" status therefor, a central memory for storing a first set of data indicating the features pre-selected by the respective subscribers for their associated terminals in the "in" status and a second set of data indicating the features pre-selected by the respective subscribers for their associated terminals in the "out" status, and processor means responsive to said signals and said first and second data stored in said memory to activate the appropriate features corresponding to the "in" or "out" status in the terminal associated with the inputting subscriber as that subscriber enters and leaves the premises, said input means being connected to said processor means over a communications link.

2. A telephone system as claimed in claim 1, wherein said input means comprise portable personal identification devices to be carried by the subscribers, and a reader for reading said devices as the subscribers enter and leave the premises.

3. A telephone system as claimed in claim 2, wherein said portable personnel identification devices comprise cards with identification data stored thereon.

4. A telephone system as claimed in claim 3, wherein said identification data stored is stored in a magnetic strip.

5. A telephone system as claimed in claim 3, wherein said identification data stored is stored in a bar code.

6. A telephone system as claimed in claim 2, wherein said communications link comprises a local area network.

7. A telephone system as claimed in claim 1, wherein said memory incorporates a look-up table containing the terminal number and preferences for the "in" and "out" status for each subscriber.

8. A telephone system as claimed in claim 1, wherein said memory is included in said telephone system.
