AN APPARATUS TO COLLECT CALLING NUMBER IDENTIFICATION DATA (CNID) INTO A PERSONAL COMPUTER WITHOUT THE NECESSITY OF MAINTAINING THE PC IN A POWERED STATE ABSTRACT An apparatus for collecting calling number identifi- cation data into a personal computer without the neces- sity of maintaining the PC in a powered state. The apparatus consists of a line interface that detects ring- ing, off-hook condition, and receives the information from the telephone line. If the computer is turned off, the information is temporarily stored in a local memory. A sequence of instructions is also stored in the memory. Connected to the memory and the line interface is a microprocessor. Under direction of the sequence of in- structions, the microprocessor receives the information from the line interface and stores it in the memory if the computer is in a powered down state. When the com- puter is in a powered up state, the information is transferred from the microprocessor to the computer through a computer interface. If any information was stored in the memory, the microprocessor retrieves that information from the memory before sending it to the computer. Power partitioning supplies independent power to the line interface, the memory and the microprocessor, thereby allowing them to operate while the computer is turned off. The computer interface receives its power from the computer.
