broken-section-location from CPE to
SSG
Service-oriented diagnosis, supporting HIA service quality diagnosis within
access layer
Faults analysis & statistics
Providing statistics reports
Performance prediction DSLAM performance prediction Subscriber line performance prediction
Service capability pre-evaluation &
optimization
User profile configuration optimization
Faults Diagnosis - Connection
Main functions To locate the potential link-broken-
section from CPE to DSLAM
Technical principle
SELT/DELT test
Copper line performance data analysis
Historical data analysis
Alarm analysis
Integrated faults diagnosis
Diagnosis result Copper line fault DSL port fault DSLAM fault Upper network fault
Fault Diagnosis - HIA
Main functions To verify the PPP link from CPE to
SSG, the Internet bandwidth, and the
stability of DSL line
Technical principle
QoS configuration checking
Copper line performance data analysis
DSLAM performance data analysis
Bandwidth test
Diagnosis result PPP link fault Internet speed slow, to locate the
bottleneck

Fault Analysis and Statistics
Main functions To generate different faults data
reports to operators, mainly including
Fault oriented reports, Broadband user
oriented reports and Maintenance
efficiency oriented reports
Technical principle DSLAM performance data analysis
Result Showing the figures or reports Providing the analysis result, and help
operator prevent the faults

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

Service Profile Optimization
Main functions To optimize the users
profile, changing the
configuration until the
best profile is adopted
Technical principle DSM & DLM Line performance data
analysis
Result Users profile optimized Service quality improved More bandwidth and
service provided
