What's a Lucent Chipset DSP modem?

I'm in the process of bidding for  a very cheap modem for a computer I'm building--I intend this only as a stand by, but I can't make total sense out of the description, and I'd like to know what I'm getting (or whether the terms in the description are bogus).  So, what is:

New Lucent chipset 56K V.90 PCI
             Voice/Data/Fax Internal Modem.

       New "OEM" packaged (white-boxed). Plug-n-Play
       DSP modem installs quickly into a 32-bit PCI slot.
       These have been Highly reliable and problem-free
       modems - made with the Lucent Mars-2 chipset. .

       CD Includes Win95/98/NT Drivers and PhoneTools
          PC telephony softare. Phone cable included.

Specifically, what is the Lucent Mars-2 chipset, and what is a DSP modem?

Thanks!

Q. What is a DSP?
A. Digital signal processing is essentially the electronic processing of high-speed information, such as radio, sound, or video signals, and its manipulation for a variety of purposes. A digital signal processor (DSP) is a specialized semiconductor chip that performs high-speed mathematical computations with voice, data, and video signals and is used in wireless, modem, consumer electronics, and other communications devices.
Q. How does a DSP work?
A. Digital signal processing uses the power of digital computation, which processes information discontinuously as a discrete series of binary numbers, to manage and modify signals, such as sound and radio waves, which originate in analog (continuous) form. An analog-to-digital converter translates the continuous signals into a "bumpy" digital approximation, tracing the rise and fall of the signals comparable to a "connect-the-dots" drawing. The majority of the processing is then completed by the DSP, which essentially multiplies, sums, and converts every new piece of signal data received from the analog-to-digital converter using complex mathematical formulas. The DSP literally performs hundreds of millions of operations per second at lightning speed. Some functions the DSP can perform include filtering noise from a signal, encrypting information, removing unwanted interference, and amplifying or suppressing certain frequencies. In other words, DSPs can, for example, eliminate unwanted crackling noise from music recordings and scramble conversations on cellular phones to protect privacy. The digital information then may be turned back into an analog signal that is better than the original. DSPs can also manipulate information that is originally digital and does not require analog-to-digital conversion, such as computer graphics.
