Abstract
This paper investigates practical aspects associated to the adoption

of dynamic spectrum management (DSM) in existing digital

subscriber lines (DSL) access networks. A standard-compliant

crosstalk estimation method is utilized in order to retrieve the

crosstalk channel information needed by, e.g., a DSM level 2 system.

A DSM application framework was developed to help testing

DSM in practice and investigate the foreseen gap between the

DSM results obtained with simulations and practical achievable

data rates. This framework is based on “off-the-shelf” DSL equipments

and is responsible for coordinating and monitoring the test

procedures via DSL... (More)

the discrepancies identified in laboratory experiments, associated

to different sources of mismatch between simulations and

practice. (Less)
