Abstract: A gatekeeper (109) including a compare unit (204) and a record unit (206). The compare unit (204) receives call requests and accesses a database which is a record of where a called party picked up the call, e.g., at home, at the office, via a mobile phone, or via an emergency number. The compare unit (204) performs an analysis such as a “closest neighbor” analysis to determine the location of the user at the time of day closest to that of the present call. The call is then routed to the user at that location. The record unit (206) then makes the appropriate notation in the database for the latest call.

Abstract: Methods for improving bus performance and bandwidth utilization in a Local Area Network (LAN) are disclosed along with methods fo adapting LANs for use with differing hardware interfaces. The LANs described are based on a parallel bus architecture. Performance superiority is gained by passing data between ports on parallel circuits that individually are relatively slow, but that, in the aggregate, provide bandwidth equivalent to or greater than serial LAN's of much higher frequency. The bandwidth advantage of the parallel architecture is extended by the logical advantage which permits efficient utilization of up to 99% of this bandwidth. This logical advantage rests in the capability of establishing glare and collision avoidance schemes that result in very little wasted bandwidth. The LANs described are adapted for use with differing hardware interfaces when provided with a plurality of bus ports, where each port has associated therewith a configurable hardware interface.

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 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: 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 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.
