DSM performance on practical DSL systems based on estimated crosstalk channel information
Author
Summary, in English
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 standardized protocols. The work also discusses
the discrepancies identified in laboratory experiments, associated
to different sources of mismatch between simulations and
practice.
