A communication system () includes a portal (), a subscriber (), a service processor (), and a communication network (-) for providing communication between the portal (), the subscriber () and the service processor (). The components (-) of the communication system () are programmed to transmit registration information from the subscriber () to the portal (), transmit from the portal () to the subscriber () a coupling application (), corresponding controllable content, and a ticket identifying a communication session between the subscriber and the portal, invoke the coupling application () in response to a content type of the controllable content selected at the subscriber (), transmit the ticket and the content type from the coupling application () to the service processor (), transmit the ticket and the content type from the service processor () to the portal (), transmit supplementary content corresponding to the content type from the portal () to the service processor (), and transmit synthesized content corresponding to the supplementary content from the service processor () to the subscriber ().

Effortless association between services in a communication system and methods thereof

A method of communicating with a remote user. The method can include receiving a plurality of server requests from the remote user via a communications network. The plurality of server requests can be processed in a single user session without re-authenticating the user, and can include at least one server request that includes voice data and at least one server request that includes non-audio data. A portlet can be provided to process the voice data and the non-audio data server requests. Responsive to the server requests, data can be provided to the remote user via the communications network.

Voice enabled network communications

A boundary scan system for a data processing system using serial scan techniques for diagnostics comprises gated circuitry for each adapter card slot for controlling the propagation of controller generated diagnostic signals throughout the data processing system and the components included on the system's planar and each adapter card present, adapted to serially scan all present adapter cards and to provide electrical conduit to the next serially connected component in the absence of a card at an adapter slot.

Data processing system with modified planar for boundary scan diagnostics

A system and method is provided for dequeuing connection requests in a data communications system comprising a calling subsystem and a called subsystem connected by a serial simplex switch. The connection requests are made by the calling subsystem to the called subsystem by sending a connect request message to the switch and queuing the connect request message in a buffer therein. The switch establishes a connection between the calling subsystem and the called subsystem by thereafter queuing the connect request message in a buffer in the called subsystem. Concurrently, the switch sends a connect request acknowledge message to the calling subsystem while the calling subsystem sends a connect request dequeue message to the switch. To prevent loss of synchronization between the calling subsystem and the switch, the connect request dequeue message received by the switch is interpreted as a disconnect request message and the connect request acknowledge message received by the calling subsystem is interpreted as a connect request dequeue acknowledge message. The connect request dequeue message and the disconnect request message are identically serially encoded, as are the connect request acknowledge message and the connect request dequeue acknowledge message, to enable such interpretation.

Method and system for dequeuing connection requests in a simplex switch

A sequencing scheme is provided for prioritizing bus operations occurring in simplex switches which interconnect subsystems in a data communications system, thereby yielding improved aggregate system data throughput. The sequencing scheme provides procedures which simultaneously accommodate (i) concurrently pending requests to a first control bus which processes only circuit switched operations and (ii) concurrently pending requests to a second control bus which processes only packet switched operations, in an order which optimizes link level control message throughput of the simplex switch. The control messages which are coordinated by the sequencing scheme include connect and disconnect requests, connect and disconnect request acknowledgments, and data acknowledgments. All connect request and disconnect requests are managed by a connection processing (CP) bus, which operates as a circuit switching bus, and all data acknowledgments and connect request acknowledgments from subsystems attached to a cascaded switch are made over an out-of-band (OB) bus, which operates as a packet switching bus. Because connect and disconnect operations over the CP bus can proceed independently of acknowledgment operations over the OB bus, the sequencing procedures for each of the control buses are permitted to operate independently and simultaneously.

Method of sequencing bus operations in a simplex switch

A serial simplex switch design is provided which includes I/O ports each of which is configurable specifically for attachment to a data communications subsystem or, alternatively, for cascaded connection to a similarly configured I/O port on another switch. The switch provides a packet routing function including input and output buffers for each of its I/O ports wherein packets of control messages sent by one subsystem are temporarily stored prior to being delivered to the appropriate destination subsystem. When configured to be directly attached to a subsystem, the I/O ports separate control messages from incoming integrated data and control message strings. In a cascade configuration, however, a mechanism is provided wherein data and control messages are separated into two physical paths to eliminate the delays associated with integrated data and control message flow through the cascaded I/O port. Each I/O port is configurable to either of these methods of operation by means of programmable latches associated with the I/O port.
