8. The method of claim 1, wherein:

said transmitting, with said packet data signal tester via said packet data signal communication channel, one or more test packet data signals comprises transmitting a plurality of test packet data signals; and

receiving, with said packet data signal tester from said packet data signal transceiver via said packet data signal communication channel, one or more response packet data signals responsive to said one or more test packet data signals comprises receiving a plurality of response packet data signals responsive to said plurality of test packet data signals.

9. The method of claim 1, wherein:

said transmitting, with said packet data signal tester via said packet data signal communication channel, one or more test packet data signals comprises transmitting said one or more test packet data signals via a first one or more signal frequencies; and

receiving, with said packet data signal tester from said packet data signal transceiver via said packet data signal communication channel, one or more response packet data signals responsive to said one or more test packet data signals comprises receiving said one or more response packet data signals via a second one or more signal frequencies.

10. The method of claim 1, further comprising storing, in said packet data signal transceiver, a plurality of data indicative of each one of said one or more response packet data signals to be transmitted, with said packet data signal transceiver via said packet data signal communication channel, responsive to a corresponding one or more of said one or more test packet data signals.

11. The method of claim 1, further comprising storing, in said packet data signal transceiver, a plurality of data as a plurality of indices in a lookup table indicative of each one of said one or more response packet data signals to be transmitted, with said packet data signal transceiver via said packet data signal communication channel, responsive to a corresponding one or more of said one or more test packet data signals.
