What is RAO2 Fibre?

RAO2 stands for Resiliency Access Option Two. RAO2 leased line circuits are the gold standard in Internet resilience, providing diversely routed fibre from the customer premises to the Internet Service Providers network. RAO2 is available as two different services RAO2 Standard and RAO2 Plus.

What is RAO2 standard?

RAO2 Standard provides two leased lines from a customer premises that connect to the same telephone exchange. Each fibre leased line uses a different route and duct from the customers premises to the same exchange protecting against fibre breaks at the customer premises however RAO2 standard does not protect against a telephone exchange failure.

What is Active Active Internet Resilience?

An Active Active Internet services utilises both Internet access circuits at the same time. If you had two 1Gbs Internet leased lines, then both circuits would be active providing up to 2Gbs of Internet access. Should one line fail service speed would be reduced but service would continue on the primary line.

What is Active Passive Internet Resilience?

In an Active Passive configuration one Internet circuit will be designated as the primary service and in the event the primary circuit failed traffic automatically fails over to the secondary service. Once the primary circuit has been restored, traffic reconverges to the primary leased line.
