Abstract

Claims (33)

1. A method for localizing a defect in an in-house access plant operable to carry broadband communication services, said method comprising:

establishing, by at least one communication device within a diagnostic system, an automated and interactive communication session with a user of said in-house access plant;

instructing said user through said communication session to manipulate in-house equipment;

determining, by the at least one analysis device within the diagnostic system, timing information for each manipulation that is carried out;

performing, by the at least one measuring device within the diagnostic system, remote quality measurements over said in-house access plant while said in-house equipment are being manipulated;

identifying, by the at least one analysis device, from said timing information a particular manipulation that is time-correlated with a substantial change in measured quality,

thereby identifying a particular piece of in-house equipment that has been manipulated and in the neighborhood of which said defect is located.

2. The method according to claim 1 , said method further comprising:

instructing said user through said communication session to take notice of times at which said in-house equipment are manipulated, thereby determining said timing information, wherein

said identification step is performed by said user.

3. The method according to claim 1 , said method further comprising:

receiving through said communication session an interactive signal for said each manipulation, such that said timing information is derived,

wherein said identification step is performed by an analysis tool.

4. The method according to claim 1 , wherein said communication session is a phone call guided by an intelligent voice responder.

5. The method according to claim 1 , wherein said communication session is based upon a web interface.

6. The method according to claim 1 , wherein said defect is at least one of a missing and defective splitter separating a broadband signal from a narrowband signal, and in that said user is instructed to unplug narrowband devices.

7. The method according to claim 1 , wherein said defect is bad quality in-house wiring, and said user is instructed to switch on or off in-house electro-equipment causing one of noise increase and decrease on said in-house access plant through radiations picked up by said bad quality in-house wiring.

8. An analysis tool adapted to send a control signal whereupon remote quality measurements are performed over a in-house access plant operable to carry broadband communication services,

characterized in that said analysis tool is operable to form part of a diagnostic system capable of localizing a defect in said in-house access plant, and in that said analysis tool is further adapted:

to synchronize said control signal with an automated and interactive communication session established with a user of said in-house access plant, though which said user is instructed to manipulate in-house equipment, and through which an interactive signal is received for each manipulation that is carried out,

to identify, from timing information derived from said interactive signal and related to said each manipulation, and from said remote quality measurements, a particular manipulation that is time-correlated with a substantial change in measured quality,

thereby allowing identification of a particular piece of in-house equipment that has been manipulated and in the neighborhood of which said defect is located.

9. A communication unit adapted to establish an automated and interactive communication session with a user of a in-house access plant operable to carry broadband communication services, characterized in that said communication unit is operable to form part of a diagnostic system capable of localizing a defect in said in-house access plant,

and in that said communication is further adapted:

to instruct said user through said communication session to manipulate in-house equipment,

to receive through said communication session an interactive signal for each manipulation that is carried out, whereby timing information related to said each manipulation are derived,

to send a synchronization signal whereupon remote quality measurements are performed over said in-house access plant, which remote quality measurements being performed while said in-house equipment are being manipulated,

thereby allowing identification, from said timing information and from said remote quality measurements, of a particular manipulation that is time-correlated with a substantial change in measured quality,

and further of a particular piece of in-house equipment that has been manipulated and in the neighborhood of which said defect is located.

10. A diagnostic system adapted to localize a defect in a in-house access plant operable to carry broadband communication services, said diagnostic system comprises:

a communication unit adapted to establish an automated and interactive communication session with a user of said in-house access plant, to instruct said user through said communication session to manipulate in-house equipment, and to receive through said communication session an interactive signal for each manipulation that is carried out,

a measurement unit adapted to perform remote quality measurements over said in-house access plant while said in-house equipment are being manipulated,

an analysis tool coupled to said timing unit and to said measurement unit, and adapted to identify, from timing information derived from said interactive signal and related to said each manipulation, and from said remote quality measurements, a particular manipulation that is time-correlated with a substantial change in measured quality, thereby identifying a particular piece of in-house equipment that has been manipulated and in the neighborhood of which said defect is located.
