摘要： A voice adaptation device (18) provides an interface between a narrowband local access network and a broadband asynchronous transfer mode (ATM) backbone network (16). The voice adaptation device (18) includes a T1/E1 network adaptor (50) that converts T1/E1 signals carrying narrowband voice traffic into an ATM cell format. The T1/E1 network adaptor (50) also performs echo cancelling, voice enhancement, digital voice protocol conversion, and compression/decompression on the narrowband voice traffic. The voice adaptation device (18) also includes a synchronous optical network formatter (52) that places ATM cells generated by the T1/E1 network adaptor (50) into synchronous optical network signals. The synchronous optical network signals are transmitted across the broadband ATM backbone network (16).

摘要： A packet telephone system which employs a packet network that provides virtual circuits. The packet telephone system employs short packets containing compressed speech. The use of the short packets makes possible compression and decompression times and bounded delays in the virtual circuits which are together short enough to permit toll-quality telephone service. The packet telephone system employs an intelligent network interface unit to interface between the packet network and standard telephone devices. The network interface unit does the speech compression and decompression and also responds to control packets from the packet network. Consequently, many telephone system features can be implemented in the network interface unit instead of in the switches. The network interface unit may also be used to provide data connections to devices attached to it. The combination of virtual circuits, with bounded delays, short packets, rapid compression and decompression, and intelligent network interface units makes it possible to build a telephone system with fewer and cheaper switches and fewer links for a given volume of traffic than heretofore possible and also permits substantial savings in provisioning and maintaining the system.

摘要： PROBLEM TO BE SOLVED: To obtain IP (Internet protocol) network communication equipment capable of surely eliminating echoes in a self-station side by enhancing the calculation accuracy of time delay of incoming and outgoing transmission paths.
SOLUTION: A control packet including a transmitting time is transmitted to the opposite station through an IP network 5, and when the control packet is returned from the opposite station through the IP network 5, the delay time of the incoming and outgoing transmission paths is calculated from a receiving time of the control packet and the transmitting time included in the control packet. This can accurately calculate the delay time of the incoming and outgoing transmission paths even if the transmitting side transmission path is different from the receiving side transmission path to consequently and surely be able to eliminate echoes in the self-station side.

摘要： A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data. A digital transmission protocol which is consistent with current packet standards is used to create an independent channel through use of a modified supervisory packet for negotiating communication parameters, including the speech compression algorithm, the speech compression ratio, the communication multiplex scheme, and other operations needed for control of remote hardware interfaces.

摘要： A Multiservice Access Concentrator (MAC) receives information comprising at least one data stream, at least one voice channel, at least one video stream, Local Area Network (LAN)-based traffic, and facsimile traffic. The received data stream is packetized, and the packetized data stream is multiplexed with the voice channel and the video stream to form an integrated transport stream. The voice channel comprises compressed and uncompressed voice information. The integrated transport stream is provided to at least one multi-service network using a software-configurable trunk. The multi-service network includes cell-based and packet-based networks comprising Asynchronous Transfer Mode (ATM), Frame Relay, High-level Data Link Control (HDLC), Internet Protocol (IP), and Time Division Multiplex (TDM) networks, as well as leased-line carrier services. The trunk is configured at a physical level and a protocol level using at least one trunk option.
