1. A method for alerting a passenger of a vehicle of an incoming telephone call, the method comprising:
- receiving the incoming telephone call;
transferring to a seat electronics unit telephone information associated with the incoming telephone call and a predetermined voltage substantially larger than used by the seat electronics unit regulating the predetermined voltage by a regulator at the seat electronics unit to control a flow of telephone information for multiple passengers;
transferring the predetermined voltage and the telephone information intended for the passenger from the seat electronics unit to a passenger control unit proximate to a passenger seat occupied by the passenger, the passenger control unit including a processor, a memory and a regulator;
regulating the predetermined voltage by the regulator to provide a selected level of power to the processor;
processing the telephone information to determine whether the telephone information includes a telephone call command indicating that the incoming telephone call is being directed to the passenger control unit; and
performing a call notification scheme to notify the passenger of the incoming telephone call.

Abstract
Implemented on a vehicle, a communication system used to notify a passenger of an incoming telephone call. The communication system includes a telephony system assigned to one or more passenger(s) of the vehicle. The telephony system includes a passenger control unit ("PCU") and a passenger control handset ("PCH") coupled to the PCH, both having processing capability. Either of these units may process telephone information transferred to the telephony system, and in response of detecting a telephone call command, perform a call notification scheme to indicate to the passenger(s) that an incoming telephone call has arrived.

7. A communication system adapted for use in a vehicle, the communication system comprising:
-
circuitry for receiving an incoming telephone call and transferring telephone information and audio; a plurality of communication lines coupled to the circuitry, the plurality of communication lines including a power line to provide a predetermined voltage, a ground line to provide a ground reference and a plurality of digital data lines to provide the telephone information from the circuitry and a passenger control unit coupled to the plurality of communication lines, the processor control unit includes a processor to receive and process the telephone information to determine whether the telephone information includes a telephone call command and to perform a call notification scheme to alert a passenger of the incoming telephone call if the telephone information includes the telephone call command, the processor control unit also includes a voltage regulator to regulate the predetermined voltage in order to produce a lesser voltage used by the processor of the passenger control unit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
