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.
