Abstract
The topology of a digital subscriber line loop can play an important role in provisioning service. For example, knowledge of certain topological features in a loop can enable telecommunications companies to make better decisions about the kinds of services that can be provisioned on that loop. Additionally, knowledge of those topological features can also assist field engineers in troubleshooting problems in the field. A topology recognition engine can provide key topological features such as the loop length, presence of single and multiple bridge taps and the length of single bridge taps on a loop.
Claims22
A method for extracting topological features about a digital subscriber line (DSL) loop from insertion loss (Hlog) measurements comprising:
- computing a deviation of the Hlog measurements from straight loop Hlog measurements;
- and
- determining whether a bridge tap is present based on whether the deviation exceeds a predetermined threshold.
A system for determining a topology for a DSL loop from Hlog measurements comprising:
- a processor;
- and
- a memory comprising instructions;
- said instructions causing the processor to:
- compute a deviation of the Hlog measurements from straight loop Hlog measurements;
- and
- determine whether a bridge tap is present based on whether the deviation exceeds a predetermined threshold.
A system for determining a topology for a DSL loop from Hlog measurements comprising:
- a means for computing a deviation of the Hlog measurements from straight loop Hlog measurements;
- and
- a means for determining whether a bridge tap is present based on whether the deviation exceeds a predetermined threshold.
The system of claim 24 further comprising a means for determining a length for the single bridge tap.
