Spacecraft Processor Emulations Sample Clauses

Spacecraft Processor Emulations. The real-time simulation computer will run a high fidelity emulation of the spacecraft flight processors and software. This includes the firmware elements related to the ADCS, orbits, the propulsion subsystem, the T&C subsystem and the power. The SCE processor emulations communicate with the dynamic spacecraft models via an emulation of the spacecraft 1553b data bus to the DCU’s. The 1750 emulation uses an SS/L developed technology called the Dynamic Binary Translator (DBT) which allows the DSS to use the actual flight software load module directly. This provides for the highest fidelity possible in an all software simulator. In addition, this technology allows flight software patches to be commanded and enabled just as they are on the actual spacecraft. In addition, the redundant SCE and processor will be modeled. Also included will be software models of the various interprocessor links that exist on the actual spacecraft. These links will model the actual spacecraft data traffic this will permit realistic processor fail-over scenarios to be simulated. Also modeled will be the CCL tray interfaces to provide redundancy simulation.

  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at a P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • Network Interface Device 2.7.1 The NID is defined as any means of interconnection of the customer’s premises wiring to BellSouth’s distribution plant, such as a cross-connect device used for that purpose. The NID is a single line termination device or that portion of a multiple line termination device required to terminate a single line or circuit at the premises. The NID features two (2) independent ▇▇▇▇▇▇▇▇ or divisions that separate the service provider’s network from the customer’s premises wiring. Each chamber or division contains the appropriate connection points or posts to which the service provider and the customer each make their connections. The NID provides a protective ground connection and is capable of terminating cables such as twisted pair cable. 2.7.2 BellSouth shall permit NewPhone to connect NewPhone’s Loop facilities to the customer’s premises wiring through the BellSouth NID or at any other technically feasible point.

  • Service Specification The Parties have agreed upon the scope and specification of the Services provided under this Service Agreement in the Service Specification.

  • Network Interconnection Methods 3.1 The Interconnection provided herein may not be used solely for the purpose of originating a Party’s own interexchange traffic.

  • Scope of Interconnection Service 1.3.1 The NYISO will provide Energy Resource Interconnection Service and Capacity Resource Interconnection Service to Interconnection Customer at the Point of Interconnection. 1.3.2 This Agreement does not constitute an agreement to purchase or deliver the Interconnection Customer’s power. The purchase or delivery of power and other services that the Interconnection Customer may require will be covered under separate agreements, if any, or applicable provisions of NYISO’s or Connecting Transmission Owner’s tariffs. The Interconnection Customer will be responsible for separately making all necessary arrangements (including scheduling) for delivery of electricity in accordance with the applicable provisions of the ISO OATT and Connecting Transmission Owner’s tariff. The execution of this Agreement does not constitute a request for, nor agreement to, provide Energy, any Ancillary Services or Installed Capacity under the NYISO Services Tariff or any Connecting Transmission Owner’s tariff. If Interconnection Customer wishes to supply or purchase Energy, Installed Capacity or Ancillary Services, then Interconnection Customer will make application to do so in accordance with the NYISO Services Tariff or Connecting Transmission Owner’s tariff.
