Access Service Assure

Monitors DOCSIS® networks, reports on faults and performance, and uniquely provides expert recommendations on preventative maintenance actions.

A key application in the ServAssure Advanced solution family, Access Service Assure monitors millions of broadband devices down to the individual device level to ensure maximum performance and availability. By combining comprehensive network data collection and correlation capabilities, Access Service Assure isolates and prioritizes problems before providing quick and efficient recommendations to resolve the issues.

Customer Experience Measurement

Access Service Assure correlates and analyzes all traffic and connectivity measurements to create a unique measure of subscriber experience represented on a single screen via network health summaries. These patent-pending summaries measure network health based on simulated Mean Opinion Scoring (MOS) to determine availability in terms of Degraded Modem Hours (DMH) or Severely Degraded Modem Hours (SDMH), and identify network issues that are causing either QoS-sensitive applications or all applications to fail.

Access Service Assure Network health summaries enable you to:

• Identify the most severe problems on the network
  
• View a list of CMTSs sorted for traffic- or connectivity-related issues
  
• Get detailed recommendations in order of least cost or operational impact
  
• Compare relative performance of markets and hubs
  

Customizable Network Reports

More than 60 customizable reports offer in-depth trending, analysis, and modeling of DOCSIS networking information for informed decision-making. You can configure these reports by topology, time, threshold, number of devices, or priority to provide analysis on:

• Upstream and downstream and NSI utilization
  
• Carrier-to-noise ratios
  
• Correctable and uncorrectable codeword errors
  
• Receiving and transmitting of power
  
• Path loss
  
• CM and CMTS resets

Timely Events

Recognizing the importance of immediate notification of network problems, Access Service Assure comes with a flexible, real-time mechanism for delivering critical network events. You can subscribe to up to 30 different events, which are delivered to your Access Service Assure inbox or multiple e-mail addresses. These events cover key indicators of network problems, such as high and extremely high:

• Upstream or downstream CER
  
• CM resets
  
• High utilization
  
• High path loss
  
• CMTS resets or unavailability
  
• CM flapping

Key Benefits:

• Provides complete view of network health based on proven analysis
  
• Detects degraded performance, outages, and other network problems
  
• Identifies most severe issues that impact subscribers
  
• Offers prioritized problem resolution based on cost and operational impact
  
• Features personalized views to address specific user needs
  
• Includes configurable reports for in-depth trending, analysis, and modeling of network information
  
• Delivers time-sensitive network events via email
  
• Provides historical view to enable quick diagnosis of difficult subscriber issues
  
• Comes with SDK that works with standards-based interfaces and shares Service Assure data with existing operations and business support systems
  

Experience Unmatched Performance with Proactive Network Management

Access Service Assure provides you with the first software solution for monitoring broadband cable networks down to the device level. It combines comprehensive network data collection and correlation capabilities to isolate current or emerging problems, a robust reporting system, intelligent events, expert analysis to prioritize the problems, and recommendations to resolve the problems quickly and efficiently.

Now, you can proactively ensure that you have the available network resources to effectively deliver advanced IP services with optimal service and performance levels. Access Service Assure features health summaries and network reports that will keep your network performing optimally.

X-ray Service Analyzer

Isolates and resolves issues by providing real-time and historical data about cable modems, supporting interfaces, and CMTS.

A key application in the ServAssure Advanced Solution Suite, X-ray Service Analyzer provides detailed views of the location, configuration, settings, and performance of any cable modem on the network. X-ray Service Analyzer is the only software offering with real-time and historical data for the CM, as well as the interface and CMTS supporting that device. This provides a comprehensive view and speeds the diagnostic process, while reducing subscriber outage time and MTTR.

With X-ray Service Analyzer, you can finally obtain instant access to real-time and historical information about an individual cable modem on a single screen, rather than piecing together the same data from individual tools that are proprietary or only provide bits of information.

Data Collection and Analysis

The ServAssure Advanced software data collection engine periodically polls all elements in the broadband cable network. All data collected from the network is checked for integrity and persisted for further processing and analysis. X-ray Service Analyzer also analyzes this data and collects real-time data to:

• Pinpoint specific cable modems in the network topology
  
• Perform configuration and statistics
  
• Provide historical and real-time reports

Real-Time Viewing

With real-time viewing, X-ray Service Analyzer provides an instant snapshot of the current status of a specific cable modem, the supporting interfaces, and the CMTS. With this complete view of all the key elements providing services to a particular subscriber, you now have all the information needed to make sound analysis, including:

• Topology
  
• Settings
  
• Performance
  
• Customer LAN
  
• CMTS data
  
• HFC channel
  

Historical Viewing

With historical viewing, X-ray Service Analyzer offers guidance in resolving specific network issues by providing the historical status and performance of the network and cable modem equipment. X-ray Service Analyzer includes historical reports that enable detailed analysis of individual cable modems over time based on user-configurable variables, including hour, day, week, month, quarter, and year. Displayed in a single browser window for at-a-glance comparison and correlation, these reports include:

• Upstream RX and TX
  
• Upstream path loss
  
• Upstream CER and CNR
  
• Downstream CER, SNR, and RX
  
• Utilizations
  
• Active CMs on upstream
  
• Total consumption for CM siblings
  

Key Benefits:

• Identifies location of all individual cable modems
  
• Polls all elements in the broadband cable network and leverages existing information
  
• Provides an instant snapshot of the current status of individual cable modems
  
• Features reports for detailed analysis of individual cable modems over time
  
• Enables clear data presentation for comparison and correlation
  
• Allows ad-hoc SNMP access to cable modems
  
• Reduce Mean Time to Repair with a Total View of Individual Cable Modems, Supporting Interfaces and CMTSs - both Real-time and Historical.
  

X-ray Service Analyzer provides you with detailed views of the location, configuration, settings, and network performance of any cable modem on your network. It is the only software offering to provide real-time and historical data for the CM as well as the supporting interface and CMTS.

With X-ray Service Analyzer, you can finally obtain instant access to real-time and historical information about an individual cable modem in a single application, rather than piecing together the same data from individual tools that only provide bits of information-all on one screen. With its streamlined interface, X-ray Service Analyzer provides faster problem resolution and simplified management, improving workflow processes.
