1. In a first modem capable of communicating in analog mode, a method for initiating verification of transmit power levels in a signal point limited transmission system, wherein said first modem is configured to communicate over a communication channel with a second modem capable of communicating in a digital mode, said method comprising the steps of:

  • receiving a transmit power limit;

    selecting at least one signal point constellation having a first computed transmit power less than or equal to said transmit power limit, said first computed transmit power being calculated in accordance with a predetermined power calculation formula; and

    transmitting said at least one signal point constellation to said second modem to initiate verification of the transmit power level of said at least one signal point constellation.
