Method and device for testing subscriber premises equipment

A method for testing customer premises equipment comprising a DSL modem coupled with a telecommunication line, the method comprising:

• determining, using a monitoring device, at least one value that depends on an attenuation of a signal transmitted over the telecommunication line to the DSL modem or received over the telecommunication line from the DSL modem;
• and
• detecting, depending on the at least one value, that the DSL modem is coupled with the telecommunication line via a DSL splitter in such a way that the DSL modem is connected to a different connector of the DSL splitter than a modem connector of the DSL splitter, in order to determine which modem connector is intended for being connected with the DSL modem;
• determining, using the monitoring device, a loop length value of the telecommunication line;
• and
• determining, using the monitoring device, at least two thresholds depending on the loop length value, the detecting being based on comparing the at least two thresholds with the value,
• wherein the at least one value corresponds to a received signal power of a signal including at least one activation tone, the at least one activation tone being sent by the DSL modem over the telecommunication line.

A device for testing subscriber premises equipment, the subscriber premises equipment comprising a DSL modem coupled with a telecommunication line, the device comprising a processor configured for:

• determining at least one value that depends on an attenuation of a signal transmitted over the telecommunication line to the DSL modem or received over the telecommunication line from the DSL modem;
• detecting, depending on the at least on value, that the DSL modem is coupled with the telecommunication line via a DSL splitter in such a way that the DSL modem is connected to a different connector of the DSL splitter than a modem connector of the DSL splitter, in order to determine which modem connector is intended for being connected with the DSL modem;
• determining a loop length value of the telecommunication line;
• and
• determining at least two thresholds depending on the loop length value, wherein the detecting being based on comparing the at least two thresholds with the at least one value.
