Unlike FTTP, FTTN and FTTB, homes and businesses in NBN’s HFC network will not be provided a power resiliency policy to deal with power outages on NBN equipment
The company responsible for building the National Broadband Network, nbn, has revealed that it will not be providing a power resiliency policy to the NBN HFC network — expected to be launched in the second quarter of this year.
In its draft Wholesale Broadband Agreement, released to Access Seekers for HFC Business Readiness Testing (BRT) today, the company states that it has “made the decision that a general power resiliency policy […] will not be implemented for the NBN Co HFC Network” as the “NBN Co HFC Network architecture is different to that of the FTTB/N Networks”.
NBN’s FTTN and FTTB network benefit from having backup batteries installed within the node enclosures, enabling a certain degree of power backup for the active equipment located on the field. NBN’s Fibre to the Premises network is entirely passive in the field — meaning it is not impacted by on-field power outages.
The HFC network, which NBN will acquire from Telstra and Optus, will replace the majority of existing copper phone and ADSL/ADSL2+ services delivered over the copper network. This means that during a power disruption on NBN’s HFC equipment, homes and businesses could be disconnected any fixed-line phone or Internet connection until NBN and its power supplier resolves the issue.
This could be a significant concern for owners of security alarms, medical alarms and lift emergency phones which depend on a resilient phone connection — especially during emergencies.
I’ve written in some more detail in a previous post on the impact of power outages on nbn’s Multi-Technology Mix technologies. You can read more about it here.
