This is why large operators have a "ready for service" protocol. The customer is never billed until it is officially RFS, and to make it RFS requires more than an operational network, it also requires the customer to agree in writing that they have a fully functional connection. This is another way of hiding human error, because now the up-down-up is just part of the provisioning process. There is a record of the RFS date-time so if the customer complains about an outage BEFORE that point, they can be politely reminded that when RFS happened and that charging does not start until AFTER that point. --Michael Dillon
