Abstract: A time-division multiplexed (TDM) communication system has a dynamic bandwidth allocation (DBA) controller that is configured to reduce demand overestimation so that more optimal bandwidth allocation is achieved. Upon receiving load information from a transceiver, the DBA controller is configured to estimate an amount of change to the transceiver's reported load based on previous allocations of bandwidth to the transceiver for frames that occur during a reporting delay (e.g., the delay from the time that the load information is transmitted until it is received and processed). That is, the estimated load is reduced in an effort to account for transmissions made by the transceiver during the reporting delay, thereby preventing or reducing the amount of demand overestimation that would otherwise occur. Thus, the transceiver may be allocated less bandwidth according to a desired DBA algorithm so that more network bandwidth is available for other transceivers.

Abstract: Methods and systems for resilient network communication are provided. In one aspect, a network includes multiple edge network elements, core network elements, and off-network network elements. Each network element has multiple ports. Communication paths exist between edge network elements, traversing core network elements. A maintenance domain maintains communication resiliency in the network through maintenance domain entities that detect network communication faults. Maintenance domain entities are associated with ports of edge network elements. VLAN service provision to subscribers occurs over the network by mapping services to VLAN tags such that the service VLAN includes information about the resilient network. VLAN service assignment to maintenance domains is balanced.

Abstract: A memory system has a memory management unit (MMU) that is configured to receive data for storage into physical memory comprising a plurality of memory devices. The MMU receives a logical memory address and converts the logical memory address into at least one page address associated with data to be written to or read from physical memory. The MMU has an address translation circuit that is configured to translate each page address into a physical memory address. In translating the page address, the MMU employs an integer division operation that does not constrain the size of an arbitration map used to define the physical memory address. Thus, the operation of the memory can be better optimized using circuitry that has relatively low complexity and cost.

The worker modules notify the work administrator whether they can perform the work, along with load and capabilities. The work administrator a worker module to perform each work request. When a worker module completes the work, it notifies the work administrator. The work administration system may aggregate the results from one or more worker modules and provide a response via the API.

In some implementations, a server receives a query for network traffic playback data of network devices. The server extracts data from the query. The server obtains historical network traffic data. The server generates the network playback data by: (i) obtaining a plurality of historical network traffic elements from the historical network traffic data associated with a network device, (ii) obtaining state transitional data for each historical network traffic element of the plurality of historical network traffic elements, (iii) determining whether the state transitional data for each historical network traffic element comprises the prior state, and (iv) in response to determining the state transitional data comprises the prior state, the server appends the state transitional data to the network playback data. The server filters and provides the network playback data.

Abstract: A light pipe device may have a substantially U-shaped base with first and second leg portions. One or more light pipes may extend from one or both of the leg portions. The light pipe device may be mounted to a printed circuit board (PCB) by clipping the U-shaped based onto an edge of the PCB.

Abstract: A system for monitoring voice services has a service monitor that is configured to periodically assess the registration state of a voice service provided to a customer. If the service transitions to an unregistered state, the service monitor logs the state change and continues to monitor the service to determine approximately when the service transitions back to a registered state. Thus, over time, the service monitor tracks loss-of-registration (LOR) events and analyzes the history of such LOR events to determine when they are indicative of a network or service problem that warrants further analysis or attention by a user. Using these techniques, the service monitor may be able to detect and, in some cases, diagnose problems that are degrading voices services for one or more customers even before such customers realize that their services are degraded.

The output of the amplifier stages correspond to the output signals from the distribution amplifier. The transmission line has equally spaced connection points for the amplifier stages. The transmission line can be designed to have an impedance that results in the impedance of the transmission line with the connected amplifier stages having a final impedance that matches the input impedance to the transmission line.

Abstract: A time-division duplexing (TDD) system reduces crosstalk associated with signals communicated by coordinated dynamic time assignment (cDTA) transceivers. In some embodiments, the TDD system has both cDTA transceivers and legacy transceivers. Based on the dynamic allocation of downstream and upstream timeslots for the cDTA transceivers, timeslots for the legacy transceivers are selectively muted in an effort to limit the amount of near-end crosstalk (NEXT) that occurs in the TDD system. Thus, subscriber lines coupled to both cDTA transceivers and legacy transceivers may be bound within the same binder without significantly increasing crosstalk to unacceptable levels.

Abstract: A filter for performing access control list (ACL) filtering may be used in place of highly-complex and resource-intensive TCAMs for access control. In this regard, the filter may be configured to compare packet header information to action-priority pairs stored in ACL tables. Each action-priority pair indicates at least one action to be performed for implementing a desired rule and a priority for that action. An access control action from an action-priority pair matching the header information may be performed in order to implement a desired access control rule for the received packet. If multiple action-priority pairs from the same table match the header information, then the priorities of the matching action-priority pairs may be compared to resolve the conflict. The circuitry of the filter is arranged such that exact-match searching can be performed on the ACL tables to reduce the complexity and cost of the filter.

Abstract: The present disclosure generally relates to systems and methods for ensuring proper installation of telecommunication equipment. A system in some embodiments has a mobile device equipped with an image sensor that is used to acquire one or more images of a telecommunication equipment component that has been installed. The mobile device may then evaluate at least one such image to determine whether the component has been correctly installed. In addition, the evaluation performed by the mobile device may also be used to ensure that a captured image of the component meets certain predefined criteria for helping the user to capture a quality image of the component for the purpose of proving that it has been correctly installed. Thus, it is more likely that the image will be later useful for establishing that the component has been correctly installed, thereby possibly preventing the need for a truck roll.

Abstract: A system for detecting an optical network condition, such as a fiber bend, has an optical line terminal (OLT) that is configured to communicate control information with optical network terminals (ONTs) indicating the transmit power levels and the receive power levels of optical signals, such as optical data signals, that are communicated between the OLT and the ONTs. Based on such information, line losses at different wavelengths are determined and then compared in order to detect an optical network condition, such as a fiber bend. Since the measurements can be performed on optical data signals ordinarily communicated between the OLT and the ONTs, the testing may be performed during data communication. Further, as long as optical communication between the OLT and the ONTs is possible, a fiber bend or other network condition may be detected at any point along the optical path.

Based on the detected module type, the controller is configured to control the electrical characteristics of the OLT circuitry so that it is compatible with the electrical and operational requirements of the optical module. Thus, the OLT is compatible for use with any of a plurality of optical module types.

In one aspect, a system includes multiple artificial intelligence skill agents that have each been trained to perform different actions in a telecommunications system. The system also includes an orchestrator agent that interacts with each of the artificial intelligence skill agents and coordinates which of the artificial intelligence agents performs actions in response to user inputs.

The orchestrator agent transmits an instruction to an artificial intelligence skill agent to perform an action that provides a response to the intent. In response to receiving the instruction from the orchestrator agent, the artificial intelligence skill agent performs the action when the artificial intelligence skill agent is capable of carrying out the action.

Abstract: A coupling module can be used to communicate high speed signals between an optical transceiver and a processing module of an optical communication device, such as an optical line termination (OLT) or an optical network unit (ONU). The coupling module can adjust the common mode voltage level of a differential signal output by the optical transceiver to the common mode voltage level required by the processing module. In addition, the coupling module splits each of the differential output signals from the optical transceiver and passes the split signals to both a high-pass filter and a low-pass filter that are connected in parallel. An adapter module can be connected to the coupling module such that the coupling module can receive different differential signals from different optical transceivers.
