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 system and a method for managing incoming calls within a call queue include a network bandwidth monitor for monitoring network bandwidth availability on a call center and a queue call rate monitor for determining a total of all call charge rates associated with the calls. A queue manager determines the order of advancement of the calls within the queue. If the network bandwidth monitor determines that network bandwidth availability is below a predetermined threshold, high network bandwidth calls are preferentially advanced to free up additional network bandwidth. Calls with high charge rates are preferentially advanced if the total call charge rate in the queue exceeds a predetermined maximum threshold. If the maximum total call charge rate threshold is exceeded and the network bandwidth availability level is below the minimum threshold, a relative priority for maintaining network bandwidth availability and reducing total call charge rates will determine the order of call advancement.

Abstract: Asymmetric Digital Subscriber Line (ADSL) data service and Plain Old Telephone Service (POTS) are provided over a subscriber loop by an ADSL transceiver and a control processor located in a local communication center, and a subscriber ADSL modem at the subscriber location. The control processor is responsive to a detection of an origination of a POTS call for generating a first control signal that causes the ADSL transceiver to load ADSL data into tone bins which are only in a frequency band above a predetermined frequency band used for a POTS call for data transmissions over the subscriber loop. The control processor is also responsive to a detection of a termination of a POTS call for generating a second control signal that causes the ADSL transceiver to load ADSL data into tone bins which are in both the predetermined frequency band used for a POTS call and the frequency band thereabove for ADSL data transmissions over the subscriber loop.

Abstract: A CDMA communications system that can shorten a delay time until the establishment of traffic, and prevent excessive transmission power. Although transmission request signals RQ1, RQ2, RQ3, . . . sent from mobile stations through a common channel undergo only open loop power transmission control, and hence have large fluctuations in their received levels, their interference amount to message signals can be kept low because their received power is averagely about 1/a of that of the message signals MSG1, MSG2, MSG3, . . . The message signals are sent from the mobile stations in accordance with the power transmission control bits contained in a forward link signal ACK sent from the base station, followed by closed loop power transmission control. This enables the received level fluctuations at the base station to be kept low.

Abstract: Control of a packet communications network in a fixed network used by a mobile communications network is performed. (1) A communication hold mode is set for a user when the traffic volume of the user's transmission or reception of a packet per fixed time period is less than a predetermined value. The communication hold mode is defined as “although the network resources are released once, a mobile station and a gateway center at an interface with an external network behave to the user side and the external side as though the communication hold mode were maintained”. (2) When the user in the communication hold mode restarts the transmission of a packet, the mobile station automatically carries out a recall processing without the intervention of the user, and re-establishes the communication up to the gateway carrier.

Abstract: A method and apparatus for preventing network rerouting when the overhead associated with the reroute operation could result in system resources being overwhelmed.

A comparator determines whether the amount of congestion and CPU utilization is beyond an acceptable predetermined threshold. A reroute control unit prevents rerouting if the amount of link congestion and CPU utilization exceeds the predetermined threshold.

Abstract: Apparatus, and an accompanying method, for transmitting a frame synchronization signal and a data signal simultaneously through a serial transmission medium (170). Specifically within a data transmitter (105), a frame synchronization signal, a clock signal and a data signal, are encoded to form a single bi-phase mark signal having the frame synchronization signal incorporated into the bi-phase mark signal as a phase-shift. The bi-phase mark signal is then transmitted through a suitable serial transmission medium. A receiver (175), connected to the transmission medium, receives and amplifies an incoming bi-phase mark signal appearing on the medium, and, in turn, synthesizes the clock, frame synchronization, and data signals from this bi-phase mark signal.

Abstract: A system and method for silent Automatic Call Distributor (ACD) call monitoring in a telephony-over-LAN environment includes an ACD agent terminal for handling incoming calls from customers. A first call between the agent terminal and a customer terminal includes agent voice data and customer voice data. After the agent terminal has set up the first call with the customer terminal, the agent terminal receives a monitoring call setup request from a supervisor terminal. In response to the call setup request, the agent terminal cooperates with the supervisor terminal to establish a monitoring call over which the agent terminal transmits the agent voice data and the customer voice data to the supervisor terminal. The agent terminal monitors the first call for simultaneously transmitted agent voice data and customer voice data.

Abstract: An apparatus and method for coordinating multiple user responses solicited from a user during a session with a call processing application includes receiving a first transmission from a user via a communication network, the transmission causing a voice channel control unit of an IVR unit to open a voice-form voice file. A first request is transmitted to the user, soliciting a first user response, the request being stored in a voice file database of the IVR unit. After receiving the first response, the first response is recorded into the voice-form voice file. A second request is transmitted to the user requesting a second user response. The second user response is appended to the voice-form voice file after it is received. A termination message is transmitted to the user informing the user that the current interaction with the IVR unit is complete. A system administrator configures the call processing application stored in an application database of the IVR unit.

Abstract: An interface unit for a telephone receives data from an external source, such as an ISDN switch. Some of the data from the external source can be displayed on a display of the telephone. The interface unit also receives user inputs from various keys on the telephone, including a set of dialog keys. The interface unit includes a user interface that generates menu messages for displaying and operating a set of menus on the telephone display. A user of the telephone can use the dialog keys to navigate through the menus and perform a variety of actions, including executing telephone functions and changing the configuration of the telephone. A display data selector within the interface unit receives the data from the external source and from the interface unit and selects particular data items to be displayed on the telephone display. The selection of data to be displayed is based in part on the operational state of the telephone. The telephone has an active state, a configuration state and an idle state.

Abstract: A synchronization equipment performs correlation processing between a first known pattern included in a received signal and a second known pattern, and detects reception timing of the received signal. A correlation value computing portion computes a correlation value between the first known pattern and the second known pattern at every reception time. A reception timing detection portion compares the computed related value with a predetermined threshold value, determines the reception time when the correlation value becomes larger than the threshold value to be the reception timing of a received signal, and, after this determination, suspends the comparison between the correlation value and the threshold value, and holds the reception time determined to be the reception timing.
