− Need for large quantities of Bandwidth – both in DS and US directions
− Future bandwidth implementations should accommodate re-use of existing spectrum and infrastructure – no or minimal upgrades

• PHY chip is moved from CCAP to RPD (VCCAP)
• Centralised software with Satellite architecture
• Address Power Issues in the HUB
• Higher order Modulations
• Spectrum moves from HUB to NODE

Too many different element managers, probes etc.. for monitoring different aspects of Video Service.
NOC is working with multiple (Event Monitoring Solution)EMS consoles to look for problems.
Inability to pro-actively catch, track and monitor during outages situation
Lack of visibility into impact of outage on the service footprint (NYMA wide / Specific to channel / Source vs provider issue)
Fiber issues leading to truck rolls on to the fields
Upgrade/Firmware/OS Issues and tracking
Scenario
20
11/13/2017 CYIENT © 2017 CONFIDENTIAL11/13/2017
Lack of Correlations between EMS
Missing Console and Dashboards for Segregated Environments
Missing CMTS/uBR/CCAP outage impacts
DOCSIS 2/3 CMs
- Registered vs Unregistered
- US vs DS ports Utilized
- Correlation of SNR to Inbound/Outbound Errors
Main Problem
21
Siloed Issues and no grand scheme or direction of resolution
11/13/2017 CYIENT © 2017 CONFIDENTIAL11/13/2017
CMTS(Traps/KPIs) via EMS correlation into one MOM for report and capturing outages.
- 75% over Utilized vs CM count and availability for abusers and offenders
Review of outages and analysis transformed into actionable/clear-kill alarms only to Operational boards including CMTS/uBR Impact escalations
Daily & weekly outage reports distributed via Tivoli across executives and managers. Did SLAs get violated?

11/13/2017 CYIENT © 2017 CONFIDENTIAL25
Conclusion
• The processes of evolution in Cable/DOCSIS and continuous technological upgrades continue
• MSOs should handle tactical challenges in moving towards these upgrades (QoS), while enhancing user experience (QoE)
Need to adopt “Carpenter & Tailor’s rules” -
“Measure Twice, But Cut Once”
