AXTRACT | QoE Monitoring

Monitoring And Management Of Customer QoE For Data And
VoIP Services

Telco & Service provider service offerings are extremly competitive and hotly contested. The leading SPs worldwide do understand that providing a robust and high quality service is key success factor #1. A high degree of service & support automation and consistent E2E QoE monitoring are the two building blocks for all those disciplines beyond - proactive service management, predictive network maintenance and zero-touch re-provisioning.

AXTRACT Product Line

AXTRACT | Carrier Grade QoE Monitoring


Quality Of Experience - Collect, Monitor, Diagnose And Analyze Your Customer´s Experience!

AXTRACT is a high-performing, fully transparent monitoring solution designed to gather high volume diagnostic load without the need to pass it through a productive 3rd party ACS.

As IP services become increasingly complex and pervasive, it is imperative for operators to be able to effectively measure and understand the Quality of Service and Quality of Experience associated with IP service delivery.

AXTRACT can significantly support troubleshooting processes by supplying a historical view and analysis of service quality, including changes of service-related parameters - ranging from user-selected device groups or categories to a single device.

AXTRACT additionally delivers near-real time information about service quality when other devices in the service delivery chain (e.g. RGW and STB) register an error.

AXTRACT DSL | DSL Quality Monitoring

The DSL bundle provides a pre-configured environment for monitoring and diagnostics of DSL gateway devices (ADSL and VDSL).

Single CPE backend features

  • Daily aggregation on common mobile network KPIs:

    • Various DSL line related errors (notably CRC errors and Link Retrain errors)

    • Downstream and Upstream Speed

    • Downstream and Upstream Noise Margin

    • Downstream and upstream Attenuation

  • Cumulative historical traffic statistics on a daily and monthly basis

  • Time series charts for collected KPIs

  • Daily aggregation on common DSL KPIs

Group based features

  • Grouping by Access Type and Bandwidth

  • Time- and event scheduled grouping

  • Average value of all latest KPI values, relevant for the current network technology over all CPEs in each group

  • Pie chart for latest access Type and Bandwidth distribution in percentage

  • Time series chart for historic Access Type and Bandwidth in absolute units

  • Time series chart for average Downstream Noise Margin and Attenuation by group

AXTRACT DOCSIS | DOCSIS QoE Monitoring

E2E DOCSIS QoE Monitoring. Programm, Collect, Monitor, Diagnose And Analyze your customer´s DOCSIS experience!

AXTRACT PNM | Proactive Network Maintenance

Proactive Network Management (PNM) enables cable operators to monitor and report conditions in the network. PNM detects, identifies, and quantifies impacts to the network, such as cable faults and ingress noise. It effectively and proactively identifies plant and subscriber home impairments and sweeps all layers of subscriber’s connection infrastructure, in search of events or problems that may be generating service degradation

  • Identify impairments before impairments impact the customer

  • Locate upstream and downstream impairments

  • Measure upstream frequency response

  • Use your cable modem as a powerful test probe and troubleshooting device


Data collection of PreEQ coefficients from Cable Modems, correlated with infrastructure data

Used to calculate:

  • MTC: Main tap compression

  • NMTER: Non-main tap to total energy ratio

  • PreMTTER: Pre-main tap to total energy ratio

  • PostMTTER: Post-main tap to total energy ratio

  • TDR: Time domain reflectometer

  • Return path

  • Frequency Domain

Full Band Capture (Downstream Spectrum Analysis)

  • Obtained from Modem’s Full Band Capture (FBC) functionality.

  • Allows to recognize and alarm field problems.

Upstream Spectrum Analysis

  • Obtained from CMTS

  • Continuous check over noise floor level in each interface to detect when the maximum threshold is being exceeded

AXTRACT LTE | LTE QoE Monitoring

The AXTRACT LTE bundle provides a pre-configured environment for monitoring and diagnostics of gateway devices with a mobile uplink (2G, 3G or 4G). There is specific support to detect if radio signal quality of such stationary devices suddenly falls.

Single CPE backend features

  • Daily aggregation on common mobile network KPIs

  • Average and worst values for current and previous day on:

    • RSSI

    • RSRP (4G)

    • RSRQ (4G)

    • SINR (4G)

    • RSCP (3G)

    • ECIO (3G)

  • Network change detection

  • Daily Single-CPE KPI baseline calculation with historical retention

  • Sample deterioration assessment based on configurable per-KPI standard deviation multipliers

  • Cumulative historical traffic statistics

  • Time series charts for collected KPIs

  • Network change history table and deterioration statistics histogram

Group based features

  • Grouping by network technology generation (2G, 3G, or 4G) and also by Cell ID

  • Time- and event scheduled grouping job

  • Average value of all latest KPI values relevant for the current network

  • Grouping by underlying network technology as pie and/or time series charts
