  • Operations and maintenace architecture for multiprotocol distributed system
    Patent number: 7313626
    Abstract: The present disclosure is directed to an open access Network Management System (NMS) that provides multiple tenants in an open access wireless distribution system with an appropriate level of access and control over the system elements that carry their signaling. For example, in addition to forwarding messages from tenant-controlled NMSs to the open access system elements, the open access NMS preferably acts as a caching firewall to ensure that the tenant NMS are permitted privileges to access only those system elements to which they are a properly assigned. A database function included with the open access NMS may be used to build and maintain a database of operations and maintenance information from autonomously initiated poll and status functions. This then permits queries from tenant NMSs to be answered without the need to duplicate open system network traffic.

  • Method and apparatus for multi-directional fiber optic connection
    Publication number: 20070286558
    Abstract: A method and apparatus are disclosed that permit multi-directional fiber optic connections to a device. The multi-directional aspect of the fiber optic connections permit the connections to be aligned closely with the direction of travel of the fiber optic cables that interface with the device. Closely aligning the fiber optic connections on the device with the fiber optic cables' direction of travel maximizes the bend radius of the fiber optic cable near the point of connection or eliminates the bend altogether and reduces the likelihood of a broken fiber or signal attenuation.
