Abstract: A method of operating a communication server in handling data from a plurality of channels, which includes receiving data of a plurality of channels, by the communication server, determining, for the channels, target times by which the channels should be handled in order to avoid starvation of the channel, estimating handling times required for processing sessions of the channel and repeatedly selecting, by a scheduler of the communication server, a channel whose data is to be handled responsive to the determined target times and the estimated handling times. In addition, a processor of the communication server is scheduled to perform, without interruption for handling of data of other channels, a processing session on the selected channel, in which the received data is prepared for transmission and placed in an output buffer and at least one driver of the communication server transmits the data prepared for transmission independently of the processor of the communication server.

Abstract: A method of scheduling the handling of communication channels by a processor assigned to handle a plurality of channels. The method includes determining for each channel, handled by the processor, a target time by which time it should receive processing, selecting one or more of the assigned channels whose data is to be handled next, based on the target times of the channels and when more than one channel is selected, choosing for handling before other channels, at least one of the selected channels based on a consideration directed at minimizing the average processing time of the channels.

Abstract: A method of transmitting signals between a source modem and a destination modem. The method includes transmitting the signals from the source modem, over a first switched network path, to a first interface, encapsulating the at least some of the signals received by the first interface into packets, transmitting the packets from the first interface over a packet-based network to a second interface, removing the encapsulation of the signals at the second interface; and transmitting the data signals from the second interface over a second switched network path to the destination modem.

Abstract: A method of handling video signals by a gateway. The method includes determining, by the gateway, that a circuit switched channel carries video signals, receiving, by the gateway, a signal stream from the circuit switched channel determined to carry video signals, placing the signals of the received signal stream in packets of a single packet connection and transmitting the packets of the single packet connection, by the gateway, on a packet based network.

Abstract: A repeater having first and second communication terminals that receives signals at either of the terminals and transmits signals responsive to the received signals at the other of the terminals, comprising: a first signal processor that receives V.90 analogue data signals from the first terminal and generates bit streams responsive thereto that accurately reproduce the data in the analogue signals; a second signal processor; and a communication channel linking the first and second signal processors wherein the second signal processor receives the bit streams generated by the first signal processor via the communication channel and transmits V.90 PCM octets responsive thereto via the second terminal.

Abstract: A method of scheduling a processor to handle a plurality of connections with respective processing cycles. The method includes estimating, for at least one of the connections, whether the connection will receive a processing session during its current respective processing cycle if each of the connections which did not yet receive a processing session during its current processing cycle receives, during its current processing cycle, an unlimited processing session and scheduling one or more of the connections that did not yet receive a processing session in their respective processing cycle, to perform a limited processing session, responsive to results of the estimation.

Abstract: A method of managing a DSL connection by a DSL server modem, including receiving signals from a DSL client modem at a first rate, determining, by the DSL server modem, a data content of the received signals, and initiating, by the DSL server modem, negotiation of a change in the rate of the DSL connection, responsive to the determination of the data content, so as to receive signals at a second rate different from the first rate.

Abstract: A method of forming a V.90 connection on an all digital connection. The method includes transmitting a request to connect from a digitally connected client modem (28) to a digitally connected server modem (24) and transmitting, by the client modem (28) to the server modem, a message requesting to form a V.90 connection, identifying the digitally connected client modem (28) as an analog connected modem.

Abstract: A method of scheduling the handling of data from a plurality of channels. The method includes accumulating data from a plurality of channels by a remote access server, scheduling a processor of the server to handle the accumulated data from at least one first one of the channels, once during a first cycle time, and scheduling the processor to handle the accumulated data from at least one second one of the channels, once during a second cycle time different from the first cycle time.

Abstract: A soft modem having a plurality of selectable operational modes. Each of the operational modes has a different nominal processor utilization level. The soft modem uses a method for changing its nominal processor utilization level while maintaining the logical connection between the local and remote data communication equipment. The method includes operating the soft modem in one of the plurality of operational modes and switching between any one of the plurality operational modes and any other operational mode of the plurality operational modes upon detecting a control signal selected from a group of predetermined control signals for changing the nominal processor utilization level of the soft modem.
