摘要： A system and method for fax transmission over a fax relay network that includes at least a wideband portion and a narrowband portion, includes a first fax relay gateway communicatively connecting a sending fax machine on the wideband portion of the network to the narrowband portion of the network, the first fax relay gateway receiving image data from the sending fax machine and outputting digitized image data in accordance with a data rate of the narrowband portion of the fax relay network. A second fax relay gateway, communicatively connects a receiving fax machine to the narrowband portion of the network. At least one of the first fax relay gateway or the second fax relay gateway includes a control process that determines whether an amount of data stored in a buffer in the fax relay gateway is greater or less than a particular threshold or determines that the amount of jitter in the narrow band network exceeds a particular threshold, and if so, initiates a retrain procedure to adjust the fax data rate.

摘要： A method and apparatus for maintaining a fax transmission over a relay network that includes at least first and second portions and a relay portion that couples the first and second portions to each other. At a second gateway connecting the second portion to the relay portion, data frames received over the relay portion are processed to determine if they are corrupted, and signals are sent back to a first gateway to resend any data frames that are corrupted. The first gateway connects the first portion to the relay portion.

摘要： A technique for detection and bypass of unnecessary modulation/demodulation and compression/decompression of Group 3 fax, in a telecommunication network having more than one pair, or “tandem,” Group 3 fax relay gateways. Detection and the effective removal of a Group 3 fax tandem reduces end-to-end processing delays of the facsimile signal, and improves performance of the Group 3 fax communication. The invention uses frequencies normally used for voice information (such as V.21 channel 1 frequencies) to detect tandem fax relay gateways and effectively remove unnecessary relay gateways.

摘要： A method for altering an operating frequency of a processor. The method includes monitoring a real-time performance indicator of a system, and determining a desired frequency in response to the indicator. The indicator may be an amount of idle time of a processor of the system. The method also includes selectively altering an operating frequency of the processor in response to a comparison of the desired frequency and the operating frequency, including increasing the operating frequency in response to the desired frequency being greater than the operating frequency, and decreasing the operating frequency only in response to the desired frequency being less than the operating frequency by more than a predetermined value.

摘要： A base station of a cordless telephone includes a transceiver, a control module, a connection handler, and a media handler. The transceiver wirelessly communicates with a handset. While the handset is operating in a standby mode, the transceiver transmits a signal to instruct the handset to exit the standby mode. The control module establishes a permanent virtual circuit with the handset that includes a predetermined user datagram protocol (UDP) port or a negotiated UDP port. The control module negotiates, with the handset to determine a feature subset of the handset and transmits packets to the handset via the permanent virtual circuit. The packets are selected based on the feature subset of the handset. The connection handler is configured to establish a switched virtual circuit with an endpoint device via a communications channel. The media handler is configured to convert media packets into first and second digital audio compression formats.

摘要： A system and method to establish an end-to-end error correcting protocol between two voice band data modems over a network including voice band data relay gateways, where part of the end-to-end connection is via low data rate narrowband network. Using a partial implementation of V.42 LAPM protocol within the data relay gateways, the system allows the independent selection of modulation schemes at each gateway as well as increased user data throughput by removing non-informational data. Flow control of the user data to match the channel rate of the narrowband network may also be provided.
