  • Publication number: 20060153070
    Abstract: An access device includes a first port configured to communicatively couple to a network node via a communications link, with the communications link having a plurality of information flows. At least one of the flows is configured as a maintenance and control flow and at least one of the flows is configured to carry customer data. The access device has a second port configured to communicatively couple to one or more demarcation devices via another communications link, and the demarcation device(s) is communicatively coupled to one or more customer premise equipment (CPE). A processing unit is configured to respond to commands received in the maintenance and control flow and to transmit access device information on the maintenance and control flow.

  • Publication number: 20050220148
    Abstract: A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames. Time-division multiplexed (TDM) signals are transported as carrier-tagged flows between customer premise equipment that communicates using TDM signals and a service edge that communicates using TDM signals.

  • Publication number: 20050220014
    Abstract: A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames. In accordance with a preferred embodiment, a discard eligibility indication may be provided with the data frames.

  • Publication number: 20050220059
    Abstract: System and method for providing a layer 2 switch in the access network that switches based upon one or more carrier tags identifying customer traffic. Customer traffic conforming to any variety of different layer 1 or layer 2 protocols may be encapsulated and identified according to carrier tag values. The layer 2 switch may determine how to handle the traffic by interpreting and manipulating the carrier tag values. The layer 2 switch may be capable of switching TDM input traffic to either TDM or packet output traffic, and switching packetized input traffic to either TDM or packet output traffic.

  • Publication number: 20050220022
    Abstract: A system and method is provided for managing access communications between the service edge of a communications service provider and a customer. Access communications are carried in the form of carrier-tagged flows, the communications traffic being appended with carrier tags having significance to handling of the traffic through access network elements. A building aggregation system is provided which couples to customer premise equipment and interfaces customer flows to carrier-tagged flows used in the access network.

  • Patent number: 6414940
    Abstract: In a distributed restoration environment, a node, upon detecting an alarm indicating a failure, after a predetermined period of time, converts the received alarm signal into a modified alarm signal and transmits the thus converted signal to the node adjacent thereto that should have received the same alarm signal to thereby effectively force the failure to be bidirectional if the original failure were a unidirectional failure. The converted signal is sent only after a predetermined period of time has passed to ensure that the failure detected indeed is an actual failure.

  • Patent number: 6294991
    Abstract: To ensure that the distributed restoration process of a DRA provisioned network proceeds only in response to true failures, the present invention DRA network provisions to each of the ports of the nodes a timer mechanism for ascertaining whether an alarm is a genuine alarm. This is done by presetting the timer with an expiration period so that an alarm is validated as a failure only upon the expiration of the timer. When validated, the value of a counter is incremented. The value of the counter is reflective of the sum of validated alarms, and is compared against a preset threshold value. And it is only when the value of the summed validated alarms exceeds the preset threshold value would the DRA process be initiated. When a validated alarm ceases, the reverse process takes place. That is, the ending of the alarm has to be validated by another timer, which could be the same timer as used for validating an alarm.
