i think the ISPs submitted their suggestion to TRAI related to FUP in response to TRAI's requirement for them to manage a certain level of quality when it comes to delivery of internet services. so basically ISP said that we cannot deliver the standards you want us to deliver unless we apply FUP to the connections. in other words, what ISPs have been promising to deliver, they have been lying all along. and when trai asked them to deliver what you promise, they said we cannot do that so we are going to use FUP excuse to fcuk the customer.
