Abstract
An arrangement is provided for detecting a matching DSL data link layer protocol. A matching-protocol detection mechanism is triggered under certain condition. The matching-protocol detection mechanism, once triggered, detects a matching protocol from at least one initiating protocol. The matching protocol is supported by both a customer premise equipment and a digital subscriber line access module and is used by both to establish a DSL connection. When the matching protocol is successfully identified, it is activated. When the matching protocol is not found, a failure is reported.
Claims26
A system, comprising:
- a customer premise equipment configured to be an initiating device and storing an initiating protocol list for establishing a DSL connection using at least one protocol from said initiating protocol list and supported by said customer premise equipment;
- a digital subscriber line access module for establishing said DSL connection between said customer premise equipment and said digital subscriber line access module using a matching protocol, said matching protocol comprising said at least one protocol and supported by said digital subscriber line access module;
- and
- a matching protocol detection mechanism for detecting said matching protocol prior to establishing said DSL connection.
A system comprising:
- a digital subscriber line access module configured to be an initiating device and storing an initiating protocol list for establishing a DSL connection using at least one protocol from said initiating protocol list and supported by said digital subscriber line access module;
- a customer premise equipment for establishing said DSL connection between said customer premise equipment and said digital subscriber line access module using a matching protocol, said matching protocol comprising said at least one protocol and supported by said customer premise equipment;
- and
- a matching protocol detection mechanism for detecting said matching protocol prior to establishing said DSL connection.
A system comprising:
- a customer premise equipment for establishing a DSL connection using one of a first set of protocols supported by said customer premise equipment;
- a digital subscriber line access module for establishing said DSL connection between said customer premise equipment and said digital subscriber line access module using a matching protocol that is one of a second set of protocols supported by said digital subscriber line access module and that matches said one of the first set of protocols;
- and
- a matching protocol detection mechanism for detecting said matching protocol prior to establishing said DSL connection, said matching protocol detection mechanism to be initialized with an initiating protocol list that records an initiating protocol comprising one of said first set of protocols supported by said customer premise equipment or one of said second set of protocols supported by said digital subscriber line access module.
The system according to claim 6, wherein said matching protocol detection mechanism is a stand-alone mechanism connecting to both said customer premise equipment and said digital subscriber line access module and operating in an internally configurable operating mode.
A matching-protocol detection mechanism, comprising:
- a triggering mechanism for activating said matching-protocol detection mechanism according to a criterion;
- a matching mechanism, connecting to both a customer premise equipment and a digital subscriber line access module, for identifying a matching protocol supported by and used by both said customer premise equipment and said digital subscriber line access module to establish a DSL connection based on an initiating protocol list;
- a protocol activation mechanism for activating said matching protocol after it is identified by said matching mechanism;
- and
- a failure processing mechanism for reporting a failure when said matching mechanism fails to detect said matching protocol.
A method for detecting a matching DSL data link layer protocol, comprising:
- initializing an initiating protocol list to record at least one initiating protocol;
- triggering a matching-protocol detection mechanism based on at least one condition;
- detecting a matching protocol from said at least one initiating protocol, said matching protocol being supported and used by both a customer premise equipment and a digital subscriber line access module to establish a DSL connection;
- activating the matching protocol if the matching protocol is identified by said detecting;
- reporting a failure if the matching protocol is not found by said detecting.
A method for establishing a DSL connection using a matching protocol, comprising:
- initializing an initiating protocol list to record at least one initiating protocol;
- retrieving a record indicating a matching protocol from said initiating protocol list supported by both a customer premise equipment and a digital subscriber line access module;
- and
- establishing a DSL connection between the customer premise equipment and the digital subscriber line access module using the matching protocol.
A computer readable medium having program code recorded thereon, such that when the code is read and executed by a computer, the computer is caused to detect a matching DSL data link layer protocol by:
- initializing an initiating protocol list to record at least one initiating protocol;
- triggering a matching-protocol detection mechanism based on at least one condition;
- detecting a matching protocol from said at least one initiating protocol, said matching protocol being supported and used by both a customer premise equipment and a digital subscriber line access module to establish a DSL connection;
- activating the matching protocol if the matching protocol is identified by said detecting;
- reporting a failure if the matching protocol is not found by said detecting.
A computer readable medium having program code recorded thereon, such that when said code is read and executed by a computer, the computer is caused to establish a DSL connection using a matching protocol by:
- initializing an initiating protocol list to record at least one initiating protocol;
- retrieving a record indicating a matching protocol from said initiating protocol list supported by both a customer premise equipment and a digital subscriber line access module;
- and
- establishing a DSL connection between the customer premise equipment and the digital subscriber line access module using the matching protocol.
