    Abstract: A method and system of setting up a call over a circuit or packet switched network. Network elements exchange an automode sequence of signals to determine a modulation that both devices support and that will be used for the connection between them. The two elements may exchange the automode signals end-to-end, and then switch to a modulation scheme by negotiating an appropriate modulation or one supported by both endpoints. Alternately, each element can execute a split automode sequence with a separate network endpoint to determine the modulation to be used between the network elements. The network elements and network endpoints may negotiate a modulation scheme by exchanging integers that are indicative of the capabilities of the network elements to determine which supported modulation scheme is most desirable in the particular configuration of the elements.

    Abstract: A voice over Internet Protocol (VoIP) positioning center (VPC) is implemented in configuration with support from a text-to-voice module, emergency routing database, and VoIP switching points (VSPs) to allow a public safety access point (PSAP) or other emergency center to effectively communicate the nature of an emergency alert notification and the area of notification to the VoIP positioning center (VPC). The inventive VPC in turn determines which phones (including wireless and/or VoIP phones) are currently in the area for notification, and reliably and quickly issues the required warning to all affected wireless and VoIP phones.

    Abstract: A facsimile communication system is provided which is capable of sending out picture data from a gateway device on a receiver side to a facsimile device on the receiver side even in the development of delays in communications caused by fluctuations in a communication network and of avoiding a forced breakdown of the facsimile communication occurring based on a judgement by the facsimile communication system that a communication failure has occurred due to the delays in communications.In the facsimile communication system, the gateway device on the receiver side, after receiving a digital instruction (DCS) signal from the gateway device on a sender side, without waiting for the receipt of a receiving preparation confirmation (CFR) signal to be fed from a facsimile device on the receiver side, returns, for itself, the CFR signal to the gateway device on the sender side and then starts to receive picture data from the gateway device on the receiver side. The gateway device on the receiver side starts to send the picture data to the facsimile device on the receiver side when accumulated amounts of received picture data exceeds amounts of data required to prevent communication failures.
