Conexant SmartSCM-56 56k Controller DFT

Flash-Upgradeable V.90/K56flex PLL-Controller Serial Chipsets

Usage: To find other modems with the same chipset.

All drivers, downloads & info on this site are found via the modem.
Each Modem Manufacturers’ page also has external web-links, where available.

General Information

Modems with this chipset are designed to work with a ‘Smart-DAA’, hence the name.

The standard device ID was changed for this chipset in the ACF series (see below) to--as exampled by the DFS chipset--“RSS0303”. Manufacturers then commonly changed the chipset, but kept the same modem name + device ID.

This series of modems--which can be identified by the presence of a “PLL” in the ati6 response, typically with 2 MB of Flash-ROM, allowing either V.90 or K56flex connection--looks like this (new to old):

• SC56D - 06827-xx
• SmartACF - P9373-xx
• SmartSCM - P2106-xx (embedded)
• Rockwell -> Conexant
• RC56D2 - R6764-6x

The “D” in the name indicates that the modem downloads Firmware controller- & datapump-modules into the chip whilst in operation. This method of operation provides flexibility to the manufacturer in customisation of the modem. In addition, if Flash-EEPROM is provided, the modem Firmware can be upgraded by the customer. (The difference between this & the HCF-modems--which use a very similar method of operation & even share module-code--is that these modems contain a Controller in silicon, whereas the H-ost C-ontrolled M-odems use the computer for controller functions).
