Analyses and optimisation of ADSL lines using Ericsson CPM system

In this article we explain approach in using Copper Plant Manager System (CPM) for analyses of ADSL lines in production of broadband (BB) Operator. Results of monitoring and optimization are shown. In our case optimization is done by DAO subsystem. Operator wants maximize service availability with minimum decrease of service characteristics specially speed in downstream. CPM has purpose for monitoring of all performances of BB system as well as interdependency of lines. CPM monitoring and optimization of line parameters is based on changing of End User Profiles and using line testing mechanism integrated in DSLAM devices.
