Abstract: An originating endpoint supports visual presence indications. The originating endpoint determines a destination endpoint with which to establish a desired communication session. A network communicates a notification message to the destination endpoint regarding the desired communication session. Prior to establishing the desired communication session and in response to the notification message, the originating endpoint receives image capture data representing the surroundings of the destination endpoint. The originating endpoint may then determine from the image capture data whether to continue or terminate the attempt to establish the communication session. Visual presence indications may increase productivity by reducing the time that would otherwise be spent on unsuccessful call attempts. Visual presence indications may also conserve network bandwidth and processing resources that would otherwise be spent on the unsuccessful call attempts.

Abstract: A system for modeling real time systems includes a plurality of modules for modeling components of a system. Each module represents a single component of the system or other systems that compete for system resources. In one embodiment, each module is XML-based. Each module can also include instructions to log appropriate transactions. The system creates the loads and delays which are then logged for later analysis.

Abstract: A telecommunications server includes a bio-print control server including one or more identification databases, a transmit/receive unit, a compare unit, and a routing control unit. Various network clients may include bio-print input units. In operation, according to certain embodiments, the user can input the bio-print using any of the selected network clients. The input is then transmitted to and received via the transmit/receive unit at the telecommunications server. The telecommunications server accesses the database(s) and compares the received bio-print input with its database to determine if there is a match. If so, then the user is given a predetermined level of access to the network client from which the bio-print has been received.
