Abstract: A communications system may be used for transmitting and/or receiving data over a network. The system needs to exchange capability information with other systems in the network, in order to determine which forms of communication can be mutually supported. The exchange of information includes logical expressions involving two or more parameters. This allows, for example, a system to indicate that a higher error rate will occur if the throughput is increased. In the preferred embodiment, each capability parameter is specified in terms of a range between a minimum and a maximum acceptable value.

Abstract: Office workers are equipped with a telephone and a desktop computer, the latter including an email system which allows telephony applets to be included in email messages. Thus the recipient of a message which includes an applet might typically be presented with a call back button. When this button is selected, it automatically provides the recipient with a telephone connection through to the sender of the message. This is accomplished by the applet using JTAPI to interact with the appropriate telephony equipment in order to form the desired connection.

Abstract: A communications system may be used for transmitting and/or receiving data over a network. The system needs to exchange capability information with other systems in the network, in order to determine which forms of communication can be mutually supported. The exchange of information includes logical expressions involving two or more inter-related quality of service parameters. This allows, for example, a system to indicate that a higher error rate will occur if the throughput is increased. In the preferred embodiment, each capability parameter is specified in terms of a range between a minimum and a maximum acceptable value. Application is to an ATM network with end terminals T1 and T2 communicating via switches S1-S4.
