and RF Data, Mapping, Correlation groups and more.
Accessed from a Single User Interface
Automatically identifies downstream
spectrum issues. View historical spectrum.
Rescan CPE for current spectrum.
An optional feature that displays live and
historical return-path spectrum passing
through the CMTS.
4. Core PNM Software
Reads and analyzes pre-equalization data
Shows you where impairments are before
customers are impacted
Groups modems affected by the same
impairment
Shows devices likely being impacted in
ingress
5. What Does PEA Provide?
• Locate Upstream and Downstream Impairments
• Reduce Maintenance Costs and Outages
• Save Money, Time & Increase Customer
Satisfaction
• Harness the Power of Cable Modem Coefficients
• Know Your Upstream Frequency Response
• Determine if You Have Micro-Reflections &
Group Delay
• Know Where the Upstream Impairments
Are Located
6. Know Where to Find Impairments
PreEqualization Analyzer map with a strand map layer enabled
• DOCSIS Proactive Network Maintenance (PNM) is revolutionizing the cable industry, allowing
operators to quickly identify and locate upstream impairments in their cable plant—before
subscribers are affected.
• Results in lower maintenance costs for the cable operator and a better video, voice and data
experience for subscribers
8. Business Intelligence Dashboard
Add Widgets to the
Dashboard as they
become available.
Noise Patrol provides
details about the worst
modem on the worst
node.
16. Rank Channels to Tackle Problems
View your worst
channels and
map with one
click.
17. Cable Modem Installer/Birth Certificate
Cable modem Installer turns your smart
phone into an installation meter by using the
cable modem.
All downstream, upstream and Proactive
Network Maintenance metrics are tested at
installation.
A birth certificate is created at time of
installation associated with the tech, cable
modem and timestamp
18. Cable Modem Installer/Birth Certificate
The installer is given
PASS / FAIL values
based on the modem
KPI data. No modems
will pass if they don’t
meet your criteria!
19. Proactive Downstream Analysis
Automatic Detection of Downstream Impairments
• Suck-outs & Standing Waves
• Resonant Peaks & Adjacency
• Roll-off & Tilt
• Missing Channels
• FM Radio Ingress
View 30 days of Historical Spectrum
No Special Equipment or Probes Needed
23. Remote Downstream Spectrum
Slash capital expenditures for field test equipment
• No need for expensive meters
• Full spectrum capture for all channels (video & data)
Reduce truck-rolls and time spent in the field
• See common RF problems from any location
• See tilt, suck outs, RF notches, standing waves,
overdriven channels, resonant peaking and ingress
24. Viewing Live Spectrum Data
You can view spectrum
data from one CPE by
entering one IP
address, or you can
enter two addresses to
compare two modems
at once.
Data is color coded to the
corresponding IP address.
