770 results about "Concentrator" patented technology

In the evolution of modern telecommunications systems there was a requirement to connect large numbers of low-speed access devices with large telephone company 'central office' switches over common paths. During the first generations of digital networks, analog signals were digitized on line cards attached to the telephone exchange switches. In an effort to reduce local loop costs, it was decided to push this conversion closer to the customer premises by deploying small conversion devices in customer neighborhoods. These devices would combine multiple digital signals on a single link to a larger telephone switch, which would provide service to the customer. These devices were initially called remote concentrators or simply remotes.

DMA Controller Architecture for Receiving Requests from Non-host Devices

A chiplet hub for interconnecting a series of connected chiplets and internal resources. An HBM is mounted on top of the chiplet hub to provide multiple party access to the HBM and to save System in Package (SIP) area. The chiplet hub can form system instances to combine connected chiplets and internal resources, with the system instances being isolated. One type of system instance is a private memory system instance with private memory gathered from multiple different memory devices. The chiplet hubs can be interconnected to form a clustered chiplet hub to provide for a larger number of chiplet connections and more complex system. A DMA controller can receive DMA service requests from devices other than a system hosted, including in cases where the chiplet hub is non-hosted.

Secure provisioning and rotation of certificates for edge devices

A certificate management service (CMS) may securely provision and rotate certificates for edge devices. The CMS may pre-register a unique device ID of an edge device (e.g., provided by the device manufacturer). When the edge device is installed at the client's remote network, it is provisioned with a common bootstrap certificate that allows the edge device to initially establish a secure to connection to a local hub device and to request a client certificate. The CMS receives the request for the client certificate, which includes the unique device ID. Since the unique device ID was pre-registered at the CMS, the CMS authenticates the request for the client certificate. The CMS causes a signed client certificate to be delivered back to the edge device, which may be used by the edge device to establish subsequent secure connections.

Method for distinguishing input / output hub serial hard disk and electronic equipment

This application discloses a method and electronic device for distinguishing serial hard drives in an input / output hub, relating to the field of server storage technology. The method involves first acquiring the Peripheral Component Interconnect (PCI) device information of the serial hard drive to be identified (including manufacturer identifier, device identifier, and bus device function address indicating its physical location), and simultaneously acquiring the identifier of the input / output hub (IOH) controller (including manufacturer identifier, device identifier, and the address range of the IOH in the PCI topology). By comparing these two types of information, the control unit to which the hard drive belongs is determined. If the hard drive belongs to the IOH controller, it indicates that its interface is an IOH SATA type directly associated with the IOH. If it does not belong to the IOH controller, it can be excluded as an IOH SATA hard drive, pointing to an M.2 SATA interface type. This method bypasses the consistent SATA protocol of both, utilizing the difference in physical connection and control affiliation to achieve accurate differentiation of interface types.
