摘要： A method for reducing Internet bandwidth used for data transfer between an originating modem and an answering modem over a VoIP connection is provided. Idle data received from the originating modem is detected by an Internet node. The Internet node does not forward the detected received idle data over the VoIP connection. To keep the modem connection between the originating modem and the answering modem alive, the Internet node regenerates idle data and transmits the regenerated idle data to the answering modem upon detecting no data received for forwarding to the answering modem.

摘要： Method and apparatus for synchronizing two de/compression modems, e.g. V.42bis modems, in a voice frame network, the modems each being connected with a corresponding gateway to form a corresponding segment, are described. The method includes terminating the physical layer at either end of the corresponding gateways; negotiating at either gateway a physical layer and error-correcting data link layer with the corresponding modem; sending from either gateway to an associated modem in response to any poll command therefrom a not-ready message; signaling the other gateway when physical layer and error-correcting data link layer negotiations have been completed; and when each gateway has signaled the other that negotiations have been completed, halting the not-ready message-sending and sending instead a ready message to a corresponding modem, whereby synchronized compressed and decompressed data transmissions between the modems commences on a reliable transport. Preferably, thereafter, and upon occurrence of a destructive break condition or receipt at either gateway from a corresponding modem of an initiate data transfer command, such condition or receipt is relayed from a segment where it is detected to the other segment, thereby maintaining synchronization between the modems. Preferably, the messages and commands are compliant with the ITU-T V.42 protocol.

摘要： The present invention is a two-pass method and apparatus for achieving maximal data compression for a voice frame modem relay channel between two endpoint modems. The method includes transitioning the channel from a voice mode to a modem relay mode of operation; negotiating maximal compression parameters for either of two endpoint segments; communicating the same from one segment to the other; and then negotiating maximal end-to-end data compression parameters based upon the negotiated endpoint segment compression parameters. The end-to-end negotiation preferably involves re-negotiating one of the endpoint segments. The apparatus includes a dual first-pass negotiation mechanism for independently determining the maximal data compression capability of each segment; an end-to-end data compression capability determination mechanism for determining the maximal end-to-end data compression capability based upon the independently determined capability of each segment; and a second-pass negotiation mechanism for establishing the determined maximal end-to-end data compression capability for the channel.

摘要： Method and apparatus are disclosed for a data communications system in which data packets are transmitted between two data terminal units wherein idle packets are transmitted whenever there is no data packet to send and such idle packets are utilized for detecting transmission errors in order to optimize data transmission efficiency by continually increasing, decreasing or leaving unchanged the size of data packets as a function of transmission errors.
