The Intel

MD882X modem chipset delivers

simultaneous G.Lite and V.90 operation. Dual

functionality gives the user the ability to fully

utilize their ADSL G.Lite connection while

concurrently sending or receiving V.90 data,

fax, or voice over a POTS line. Modems

designed with the MD882X are easy for users

to install— no truck roll required.

Based on Intel’ Host Accelerated Modem

technology (HaM), the MD882X delivers added

savings by eliminating the controller chip. It

uses a portion of the host’ processor power to

implement G.Lite and V.90 operation.

The MD882X G.Lite chipset is ITU G.992.2

compliant and uses discrete multitone encoding

(DMT). It is capable of data transfer rates of

up to 1.536 Mbits/second downstream, and

512 Kbits/second upstream depending on line

conditions and distance from the central office.

This chipset consists of an accelerator/PCI chip

and two Sigma Delta Analog Front End (SAFE)

chips— one for ADSL and the other for V.90

operation. An optional AFE is available to

provide full-duplex speakerphone capability.

The MD882X also offers future software

upgradability for T1.413 compatibility, and

support for G.992.2 Annex B and C, and

G.992.1 Annex A, B, and C.

The MD882X includes a PCI (Rev 2.2) interface

and runs on Pentium®

III

processor (500MHz

and above) or equivalent. It is compatible with

Windows

98, ME, and 2000, and supports

legacy modems and fax standards to insure

interoperability with existing modems.

Intel has carried out extensive DSLAM

interoperability testing, and will continue to

do so. Entire end-to-end testing has also been

conducted using the LAN encapsulation mode.

The Intel MD882X G.Lite chipset is a high-

performance, cost effective PCI solution that

delivers concurrent G.Lite and V.90 operation.
