Performance Prediction - DSLAM

Main functions To generate the composite index

according to the DSLAM performance

data (mainly including CPU, memory

and bandwidth, etc.), and then

calculate the trends of composite index

and generate the prediction level of

DSLAM

Technical principle DSLAM performance data analysis

Result Drawing the performance curve Generating the prediction level Providing the possible problems based

on the prediction level

Providing the solutions to relevant prediction level

Performance Prediction - Subscriber Line

Main functions To generate the composite index

according to the DSL port and copper

line performance data (mainly including

BER, noise, attenuation, traffic and

reachable bandwidth, etc.), and then

calculate the trends of composite index

and generate the prediction level of

subscriber line

Technical principle DSL port and copper line performance

data analysis

Result Drawing the performance curve Generating the prediction level Providing the possible problems based

on the prediction level

Providing the solutions to relevant prediction level
