SP should do the calculation. But it is tempting to see the money
difference, so just that.
This 1.2% translates to about 11.616 Mbps, around 7.5 1.54Mbps DSL connections.
Assuming $50 per DSL it is around $377/PON/month. Assume one 32-port OLT
serving
1024 customers (assuming 1:32 ratio) it would be $12064/month.
Does this SP lost revenue breaks their neck, they would know?
Thanks,
