Lucent doesn't build modems, they only build modem chipsets. And v92 is not a model number, it's only a generic term that can apply to literally dozens of modems.
you need to provide answers to the following:
1: Brand and model of the modem?
2: The Lucent chipset number?
3: FCC id #?
4: Did it come preinstalled in your computer at the time of purchase?
5: If #4 is yes, the computer brand and model?
6: Is it used in a desktop or laptop computer?
7: Did it come from the factory with Windows XP installed?
