Abstract: A method and system are provided for connecting and billing a first user on an Integrated Services Digital Network to a second user on a voice-band network for packet data and circuit switched data connections. A network access device is used to extract the first user's billing information and the called party's phone number from the data packets received in the case of data packet transmission and call set-up messages received on an ISDN interface in the case of circuit switched digital connections. A voice-band call to the second user is transmitted over the voice-band network. The billing identification sent by the first user is used to bill the first user for the voice-band call established from the network access device over the public switched telephone network to the second user.

Abstract: The present invention enables multi-windowing agent computer terminals, that answer a variety of, e.g., telemarketing calls, to (i) receive call-related information from a communication system at an agent terminal for automatic display in a "telephony" window, and (ii) automatically send such information to a host computer system application software and retrieve caller desired information based on the calling or called number for display in a "host application" window without requiring a caller to provide verbal information. The present invention also enables an agent terminal to automatically transfer caller-related information from one window to another window via programmable function key commands which can be programmed by a user/system administrator regarding what information is to be copied and where and when to copy it.

Abstract: There is disclosed a processor controlled digital communication device which accepts message commands from a communication system as part of a communication protocol. These command messages are stripped from the protocol and combined within the communication device to control signaling thereat. Multi-bit time separated information (I) fields are used together with a single bit signaling (S) field. The S field bits are compiled over several frames to become the command messages.

Abstract: There is disclosed a digital telephone having dual voice and data handling capability over a single communication line. Time separated information channels are used to transport the voice and data information between the terminal and the main processor. A separate signaling channel is shared between the two information channels and information on the signaling channel is accumulated for distribution to either the voice device or the data device in accordance with address information contained within the accumulated signaling channel message.
