The filters improve broadband signal quality while preventing feedback of EMI noise from the existing building wiring to the network.

Abstract: A local area network of devices connected to a Communication Switching Module (CSM) carry both delay-sensitive information and non-delay sensitive user data in master Ethernet packets transmitted over the LAN at a constant rate. Signaling and control information from the devices initialize a permanent virtual connection (PVC) between devices and the CSM. The signaling and control information is contained in standard Ethernet packets which are encapsulated along with non-delay sensitive data in the master Ethernet packets and performs various control functions for the LAN devices and the CSM.

Abstract: A system and method for allocating bandwidth in an asynchronous transfer mode (ATM) system over-allocates bandwidth in virtual paths for virtual path groups between ATM devices. A bandwidth allocation platform manages the virtual paths in the ATM system to control allocation and to prevent congestion, while providing efficient utilization of the bandwidth within the ATM system. The bandwidth allocation system over-allocates virtual paths for virtual path groups that require additional bandwidth to make connections for calls. When a connection is selected on the over-allocated virtual path, the virtual path may use bandwidth from another virtual path in the virtual path group or from a virtual path in another virtual path group if needed. A communication device transports user communications and call signaling for a call. A signaling processor processes the call signaling to select a connection in one of the over-allocated virtual paths for the call over the virtual path group.

Abstract: A Web/Internet based toll-free network management tool that enables customers of telecommunications network providers to modify the configuration of their toll-free networks via a Web/Internet-based graphical user interface. The tool provides customers Web/Internet access to toll-free call routing plans and associated routing plan details via a secure Web/Internet-based connection, and additionally provides a customer with the ability to specify implementation of a specific call routing plan for a toll-free number at a predetermined time, and the ability to re-configure an existing call routing plan. Additionally, the tool enables a roll-back of a particular call-routing plan or call plan detail to a prior configuration at a user-specified time.

Abstract: A method for processing a SCSI bus fault in a SCSI system which has an initiator device and a target device interconnected via a SCSI bus. In response to a control command, the initiator device requests the target device to execute a specific SCSI command. Then, the initiator device processes a normal script phase in response to the SCSI command to transfer the SCSI command to the target device over the SCSI bus. If the fault occurs on the SCSI bus while the SCSI command is transferred to the target device, the initiator device retries the transfer of the SCSI command to the target device a predetermined number of times. Therefore, data damage in the target device due to the SCSI bus fault can be reduced to a minimum.

Abstract: A delay-line time-domain reflectometer includes a return detector configured to process a discharge pulse produced by discharge of a line capacitor, formed by the physical relationship of a pair of conductive wires forming a telephone line, from a predetermined DC voltage. The return detector includes a number of neural networks configured to process the discharge pulse under the control of a controller. The neural networks enable the controller to characterize the loop configuration of the telephone line, where the loop configuration includes the length of the telephone line, the position of any bridged tap connected to the telephone line and/or the length of any bridged tap connected to the telephone line.

Abstract: A store and forward receiver for a satellite communication system employs a multi-threaded command interpreter, and an associated reduced complexity audio control language (ACL) to define commands for controlling actions at different receiver sites, each of which is programmable for its own local programming purposes. Upon receipt of a relatively simple command from the headend, the interpreter accesses and executes an associated sequence of potentially locally unique, previously stored commands, causing performance of a sequence of actions, e.g., play back of potentially locally unique, previously stored information files, interleaved with portions of a headend-source commercial audio program being rebroadcast at the receiver site. This allows different affiliate stations to produce separate potentially locally unique complex sequences of actions from a single headend-sourced command for all receivers in a network grouping.

The MRMDS allows extensive modular flexibility in re-provisioning new services via changing or adding removable interfaces. Each WAN is individually connected to a distributor in the MRMDS. The MRMDS distributor interfaces the external WANs to a multiple of home/office Home Network Interfaces for distribution to a multiple of communication devices.

Abstract: A system and method for interfacing network elements using an isolated fabric interface module, which is facilitated through exploitation of standards otherwise not specified for the particular networking functions in which they are utilized. Fabric interface functionality is isolated and independent of line and switch fabric cards. Standards otherwise suitable for use in interfacing network elements are adapted for use in the isolated fabric interface configuration. The standard interfaces are adapted to extend beyond the specified length, signal traces are routed according to predetermined routing rules using matched impedance connectors, and signals are terminated to facilitate the length extension. Standard system controllers may also be used although the controlled line cards are not compliant with the standard.

Abstract: Systems and methods for using a voice-messaging system to place local and long distance telephone calls. In the invention a voice-messaging system receives a toll-free call placed by a user and verifies that the user is a valid user of the voice-messaging system by accepting a pass code. The voice-messaging system then accepts the user's request to place a telephone call and the number to be called. Finally, the system places a call to the third party and connects the telephone call to the third-party telephone line if the third-party telephone line is available.

Abstract: A method and device for frame sync detection using signal combining and correlation. The method comprises the steps of despreading PN coded signals to provide in-phase I1-In, and quadrature phase Q1-Qn signals, wherein each I1-In and each Q1-Qn signal contains at least one sync bit and n≧2. The at least one sync bit from each I1-In, and quadrature phase Q1-Qn signals are summed to form sums Is1 and Qs1, respectively. The next step provides a reference sync having at least one bit and compares each sum Is1 and Qs1 with the at least one reference bit. The results of each Is1 and Qs1 comparison are accumulated so as to form two accumulates, IA and QA, respectively. Each accumulate IA and QA, is squared to form IA2 and QA2 from which the sum IA2 and QA2 is formed. The sum IA2+QA2 is compared with a predetermined threshold and as a result of the comparison a determination of whether frame sync has been achieved is made.

Abstract: A technique for recognizing telephone numbers and other information embedded in voice messages stored in a telephone voice messaging system. A voice recognition system is coupled to the telephone voice messaging system. A voice message stored in the voice messaging system is transferred to the voice recognition system. The voice recognition system segments the voice message and then searches the segments for a predetermined speech reference model (grammar) which is expected to contain information of importance to the recipient of the message. In a preferred embodiment, the predetermined is a numeric grammar which specifies a sequence of numbers occurring in the voice message. In alternate embodiments, the grammar specifies a date, a time, an address, and so forth, and can specify more than one such type of information. The grammar can be modified or selected by the recipient of the voice message so that the voice recognition system searches for information of particular interest to the recipient.
