Hi James, Yes RO2 is just 2 diversely routed EADs, they are pure layer 2 (in fact direct fibre with media converters on the end).
Any failover has to be handled at layer 3. You pay £800 per annum per circuit for the privilege. Mostly we use RO2 with same B end and separate A-Ends thus improving the diversity by feeding the customer from separate pops, this also improves your chance of reducing ECCs as it's easy for BTOR to find a diverse route with different A-Ends. Often though even with R02 you have to accept a small pinch point near the end of the circuit. Regards...
