  • Patent number: 8625246
    Abstract: The embodiments of the present application provide a DSL protection circuit, including: a DSL and POTS broadband and narrowband mixed signal port, a narrowband POTS port, and a splitter, where the DSL and POTS broadband and narrowband mixed signal port is connected to the narrowband POTS port through the splitter, and a line on which an input end or output end of the splitter is cascaded with a restorable current-limited component for limiting abnormal current; a line on which the splitter and the restorable current-limited component are cascaded is connected in parallel with a voltage-limited component for bypass conduction of the splitter; a line on which the DSL and POTS broadband and narrowband mixed signal port is or a line on which the narrowband POTS port is cascaded with an overcurrent fuse component.

  • Patent number: 7492764
    Abstract: An element management system enables a network management server to provide a variable value to a management information base of a managed device independent of whether the managed device is served by a network address translation firewall. The element management system comprises an SNMP message manager which receives periodic heart beat frames from the managed device and stored identification of a heart beat channel in association with identification of the managed device in a registration table. The heart beat channel comprises the source socket and destination socket of the heart beat frame. The SNMP message manager further uniquely associates an assigned UDP port number with the managed device and provides the unique association of the assigned UDP port and the managed device to the network management server.

  • Patent number: 7464267
    Abstract: A system and method for establishing a shared secret media key between each of a caller endpoint and a callee endpoint for securing a real time media channel comprises: i) establishing a caller authenticated signaling session with the caller endpoint using a caller shared secret authentication key and a symmetric encryption algorithm; and ii) establishing a callee authenticated signaling session with the callee endpoint using a callee shared secret authentication key and the symmetric encryption algorithm. A caller public value is received from the caller endpoint through the caller authenticated signaling session and sent to the callee endpoint through the callee authenticated signaling session. The caller public value is a public value of a pair of values generated by the caller endpoint and useful for calculating a shared secret media key.

  • Patent number: 7430664
    Abstract: A method for securely provisioning a device for operation within a service provider infrastructure over an open network comprises the device establishing physical and data link layer network connections for communication on at least a subnet of the open network and obtaining a network configuration data such as an IP address and a subnet mask from a provisioning server that responds to a network configuration broadcast request. A device establishes a secure hypertext transport protocol connection to a first provisioning server that corresponds to one of: i) and IP address and port number; and ii) a fully qualified domain name stored in a non-volatile memory of the device. After mutual authentication, the first provisioning server provides at least one of: i) a configuration file; and ii) identification of a second provisioning server and a cipher key through the secure connection.

  • Patent number: 7290058
    Abstract: A video mail server comprises a video call signaling module coupled to an internet protocol network for establishing a first internet protocol channel with a caller remote internet video device to support a recording session over the internet protocol network and establishing a second internet protocol channel with a user remote internet video device to support a playback session over the internet protocol network. A media interface comprises a recording module for obtaining a recording sequence of compressed images representing motion video images from the caller remote internet video device and storing a video mail file representing the recording sequence of compressed images. Each compressed image frame is one of: i) an independent frame from which an image frame can be recovered utilizing only the independent frame; and ii) a dependent frame from which the image frame can only be recovered utilizing both the dependent frame and an independent frame preceding the dependent frame in the sequence.

  • Publication number: 20060274899
    Abstract: A system for securing communications between a client and an application server comprises a session key management server and the application server. The system enables network address translation firewall traversal. The session key management server comprises a key management application, a session key database, and a notification services application. The key management application receives a first transport layer security connection request from the client and negotiates a device session master key with the client as part of the transport layer security exchange. The session key database is coupled to the key management application for storing the device session master key in conjunction with an identification of the client. The notification services application coupled to the session key database and provides a notification message to subscribing application servers. The notification message comprises the device session master key in conjunction with an identification of the client.
