摘要:
A method and system for remotely managing a bridge device, such as a modem, are disclosed. Management traffic from a service provider can be communicated to a bridge device which lacks a public IP address by sending the management traffic through the bridge device to a router of a LAN. The router then sends the management traffic back to the bridge device. Thus, the service provider can perform management tasks such as troubleshooting, health monitoring, accounting, provisioning, security and firmware upgrades in a manner that is transparent to the user.

A method and system facilitates enhanced communication between a LAN and a WAN by determining which IP device of the LAN is a gateway and then restricting communication between the LAN and the WAN such that the communication is routed through the gateway. Determining which IP device of the LAN is a gateway can comprise using DHCP protocol to implement a provisioning and setup flow between a WAN bridge and gateway. By restricting communication between the LAN and the WAN such that it is routed through the gateway, features of the gateway such as a firewall and/or parental controls, can be advantageously utilized.

VoIP verification is initiated by subscriber-side test VoIP appliance, or VoIP proxy agent. Test VoIP appliance is coupled to test node over a communications internetwork by upstream and downstream datapaths. VoIP verification request is transmitted to test node. Responsively, test node transmits VoIP verification signal to test VoIP appliance. Perceivable indication of verification signal received by VoIP appliance is effected by visual display, audible indication, or both. Operational state verifier apparatus is disposed in a digital telephony device, a computer terminal, or with an ATA interface coupled to analog telephony device used in VoIP communications system.

A multi-use adapter configured to provide network connectivity for a serial bus client is provided. The adapter includes: a serial interface for coupling with the serial bus client; a network interface for interfacing the adapter with a network; and host control logic configured to interface a plurality of types of serial bus clients with a utilizing device over the network. The host control logic may be configured to detect a USB client coupled to the USB interface, to determine a corresponding driver for the detected USB client, and to retrieve the corresponding driver via the network interface.

Methods and systems for deterring spam on a communication medium are disclosed. Call traffic on the communication medium includes IP telephone calls, IM™ messages and other IP calls. The method includes detecting a call with a user device for accessing the communication medium, such as an IP telephone, a computer, etc. A signaling message associated with the call is accessed and compared with information relating to identities that correspond to originators of spam calls sent over said communication medium, which is stored in a repository associated with the communication medium, such as a dynamically updatable database. Where no match is found between the signaling message and the stored spam call identity information, the call is routed to the user. Where the signaling message matches any said spam call originator identity information however, the call is deterred from being routed to the user.

Systems and methods are provided for initiating functions on a network connectivity device, such as a router. A keypad sequence is input into the control device using a limited keypad. A command is transmitted to the router, and the router performs a function in response to the command. Accordingly, telephone handsets may be utilized to generate control commands to a router.

Client adapter and method simplify security deployment in an EPN, including the shared services electrical power lines of a premises. With direct coupling, piggybacked adapter receives network signals and electrical from EPN-connected first adapter through a shared medium port. An authenticating adapter exchanges security management services and information with supplicant adapter. Two or more adapters may be piggybacked. Piggybacked adapters exchange security management service information without rogue intrusion. Exchanged information, stored, is later used to communicate securely. Defined adjacency (neighborhood) information can be exchanged, and a neighborhood established on an EPN, where one authorized neighbors securely communicate.

A packet-based communications system is provided, including: a client communications module for transmitting digital audio signals to a user interface device over a local area network (LAN) and for receiving digital audio signals from the user interface device, a voice packet module, and a network protocol module for transmitting data packets between the voice packet module and an Internet Protocol (IP) network. The voice packet module is configured to: receive audio signals from the client communications module and encapsulate the audio signals into data packets; convert data packets into audio signals and transmit the audio signals to the client communications module. A communications device is provided, including: a microphone; a speaker; a user input device; a network interface for coupling the communications device to a local area network (LAN); an audio processing module comprising an analog-to-digital converter (ADC) for converting analog audio signals from the microphone into a digital audio signal and a digital-to-analog converter (DAC) for converting a digital audio signal into an analog audio signal, said analog signal being output by the speaker; and an endpoint communications module for connecting to a telephony adapter on the LAN via the network interface, said endpoint communications module communicating digital audio signals with the telephony adapter over the LAN.
