• 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

Giga Broadband is just door-step away with RDP


DOCSIS FDX with Fiber Deep (FD)

Traditional HFC Fiber Deep Architecture

− A calculated step to eliminate amplifiers from the network

and focus on smaller SGs− Moves the optical node deeper into the network and closer

to the subscriber− N + 0 / N + 1 Architecture− HHP / Node : 50 - 130

A Case Study

Customer Introduction

19

• Device count breakdown

• 1.1 Mil Wi-FI hotspots

• 50,000+ Devices +11-14K

Wi-Fi Hotspots

• 600+ multicast RF

Gateways

• 400+ unicast RF

Gateways

• 300+ CMTS

• 38000 CMs and CPEs

• 2500+ Servers/VMs


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


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


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?

Solution Features & Benefits

24

Features

• EMS Correlation

• Consolidation of 15 EMS

• Cause & Effect and RCA

• Utilize CMDB to auto populate info

• Outage Impact and Escalations

• CMTS past % Utilization vs Past Active CMs

• Low utilization with Low Count of Active CMs gets a lower priority

• Wall Dashboards with maps provide visual outage information

• location to help with call centers based on CMTS and uBRfailures

Benefits

• Upgrade/migrate OS/Firmware

• Reduction in MTTR

• Reliable Truck Rollouts

• Future capabilities

• Plant Power/Refuelling

• Energy consumption & saving


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”
