Abstract: A method and system provide user management of electronic message transmissions between servers and client devices, particularly transmissions of files attached to electronic messages. The method and system operate to transfer selected attached files to and from a client device. When accessing electronic messages with attached files stored at a server by a user, the attached files that satisfy a prescribed requirement are automatically downloaded from the server to the client device utilized by the user. The prescribed requirement may include maximum file size and download time, and approved list of file formats and senders. Preferably, the prescribed requirement is entered into the client device by the user. The prescribed requirement can vary depending upon the personal preference of the user. When forwarding received electronic messages with attached files, only the attached files that have been modified are uploaded from the client device to the server.

Abstract: A data communication system and method that reduces conversion distortion on data calls between locations that encode telephone signals according to different conversion standards is disclosed. The data communication system (40) includes a first switch (44) and a processor (50). The first switch (44) receives a telephone call carrying a first analog modulated data signal, and converts the first analog modulated data signal to a first digitized data signal according to a first conversion standard. Next, the processor (50) converts the first digitized data signal back to the first analog modulated data signal and then demodulates the first analog modulated data signal to recover the original data signal.

Abstract: A notification method for providing camp-on capability includes utilizing device-to-device signal exchanges via a data network. As a result, the camp-on capability may be enabled at a called communication device by means of a signal sent from a calling communication device. In the preferred embodiment, the data network is the global communications network referred to as the Internet, but this is not critical. As a response to the determination that the called communication device, such as the telephone, is in an unavailable condition, a first notification signal is transmitted from a calling communication device to the unavailable called device. The first notification signal may be an application program that is automatically executed at the called device. Alternatively, the first notification signal may be a special protocol element that triggers execution of a camp-on program stored at the called device. The first notification signal includes the network address of the calling device.

Abstract: An EOR (XR11, XR12) of outputs from a plurality of shift stages S1, S2, S4 of an M-series generator 31A is formed, thereby obtaining an M-series which has a desired delay, which in an example is a three bit delay with respect to the output code from the generator 31A. Similarly, outputs from a plurality of shift stages are combined and an EOR thereof is formed to provide another delayed M-series. An EOR of each output from the simultaneously delayed code generator 31 and an output from other M-series generator 32 is formed, thus simultaneously obtaining a plurality of Gold code series.

Abstract: The present invention relates to a system and method for multimedia messaging system collaboration. According to an embodiment of the present invention, the sender sends a message to multiple recipients. A recipient wishing to make a comment or insert changes to the message submits his comments to a moderator for approval. If the moderator approves of the changes, then the changes are automatically incorporated into the message. The original message is then automatically recalled from recipients who have not yet opened the message and a revised message is automatically sent to those whose messages were recalled. Additionally, according to an embodiment of the present invention, a message is automatically sent to those recipients who have already opened the original message to indicate the change to the original message and update those recipients.

Abstract: A data traffic network 200 in which excess cells, or cells whose transfer is expected to cause the user to exceed the QoS traffic contract bandwidth limit, are transferred to a destination node 300b via an alternate or secondary network 212. More particularly, traffic received at a first ATM node 300a (for example, an end user node) is or has been classified according to traffic type, such as voice, data, or video (with their corresponding characteristics). Prior to packetizing the data streams into the ATM fixed length packets, the ATM node 300a, 600a determines whether the QoS traffic contract bandwidth limit has been exceeded or is likely to be exceeded. If so, then the corresponding traffic is transmitted to the destination node 300b via an appropriate alternate network 212. For example, voice traffic is transferred to a PBX and, ultimately, to the public switched telephone network (PSTN).

Abstract: A telecommunications system (18) is provided that includes a first controller (20) and a second controller (22) coupled using a packet-switched network (32). The controllers provide a low cost means of coupling isochronous telecommunication devices. The first controller (20) receives one or more isochronous input channels from a common control shelf (24), such as a private branch exchange (PBX), over a circuit-switched network (27). The first controller (20) encapsulates an isochronous frames from the common control shelf (27) into a data frame that is transferrable over the packet-switched network (32). The second controller (22) is configured to receive the data frame and extract the isochronous frame, which is then transmitted to a peripheral shelf (26), such as a line trunk unit (LTU), using an isochronous circuit-switched network (38). The controllers contain identical functionality, permitting bi-directional transmission of data between the common control and peripheral shelves.

Abstract: The invention provides the user of a unified messaging mailbox with efficient, intelligent, media and device sensitive methods and apparatus to access and process (e.g., read, listen, forward, and search) messages. The invention introduces media conversion capabilities to selectively treat multimedia messages and message attachments so that they can be efficiently handled by mobile devices like PDAs (Personal Digital Assistants), pagers, or phone devices (with or without a text display feature). Furthermore, the invention introduces message content analysis capabilities that will recognize linguistic relationships between messages regardless of the media type. The invention also describes the ability to present these linguistic relationships along with the standard messaging relationships (Message arrival time, subject, sender, etc.). Still further, the invention introduces a message referencing option that allows simpler message selection from certain devices.

Abstract: An improved prompting system for accessing specified functions in an interactive voice response (IVR) system. The IVR system (101) presents a plurality of prompts to callers. The prompts are typically presented in a predetermined order. However, the IVR system (101) improves the presentation by adjusting the presentation order based on a caller pattern of prompt selection. By monitoring incoming calls to determine what prompts are most frequently selected, the IVR system (101) can tailor the presentation order to the needs of individual users. The IVR system (101) can monitor either the selections made by all users or those made by a particular individual user over a configurable time period to establish the pattern of prompt selection.

Abstract: In a multi-station transmission method and receiver using training signals, a forward signal is transformed in a signal transformation part to two pseudo-orthogonal transmission signal sequences, which are framed in base stations of two adjacent zones and augmented with orthogonal training signals, thereafter being transmitted over the same channels. A signal received by a receiver of a mobile station is separated, by a signal separation part using the training signals corresponding to the respective base stations, into signal sequences received from the respective base stations. The received signal sequences are subjected to an inverse transformation by inverse transformation circuits to obtain two transmitted signal sequences, and one of these signal sequences which has a larger metric is selectively outputted.

Abstract: A test apparatus (12) and method (110) are provided for inserting predetermined packet loss into a data flow between a plurality of hosts on a packet-switched network. The test apparatus (12) can include a first network interface (20), a second network interface (22) and a packet filter (24). The first network interface (20) receives a sequence of data packets from a source host (14) under test. Incoming data packets are passed to the packet filter (24), which selectively discards predetermined ones of the data packets to generate a reduced sequence of data packets. The second network interface (22) transfers the reduced sequence of data packets over the network (18) to the destination host (16). The test apparatus (12) can be used accurately to measure the effect of packet loss on media applications transmitting real-time data, such as voice and audio, over packet-switched networks.

Abstract: A receiver directs the center of the main beam of the antenna directivity response in a desired direction by passing signals received by n antenna elements 1a to 1d through a phase shifter 3. An output from the phase shifter 3 is passed through a receiving filter 5 and is then amplified by a low noise amplifier 6 to be delivered as an output. The phase shifter 3 is confined together with the receiving filter 5 and the amplifier 6 in a cryostat 8, and the phase shifter 3 as well as the receiving filter 5 and the amplifier 6 are cooled down by cooling means 9 through a cold stage 9a, whereby the thermal noises generated therein are reduced to a minimum.

Abstract: Techniques for enhancing the sound quality of computer telephony systems are provided. In general, digital signals including telephony sounds are converted from the time domain to the frequency domain. If noise is detected in the frequency domain conversion of the digital signals, the noise is removed utilizing a filter. The noise detection and filtering can be performed in software so that enhanced audio quality can be achieved at a relatively low cost and with flexibility for very diverse environments.
