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).

† Key
Mfc: the company no longer makes/supplies modems and/or their chipsets, or has been taken over, or otherwise fallen into commercial Tophet.
Modem: it is no longer in production.
Chip, Chipset, Family or Family-Type: it is no longer produced at the Foundry.
In short, the item marked with a † has shuffled off this mortal coil, it has gone to meet it’s maker, to sing with the choir invisible; it is, not to put too fine a point upon it, an ex-modem (-Mfc, -Chip, -Chipset, -Family or -Type).
Site Info, History & Page Stats
These pages are a LAMP-development of the original Modem-Help, UK site (most of the old HTML pages still exist, but havn’t been updated for quite some time). That site, in it’s turn, was a transfer from the first html site on free-pages at Freeserve (sadly, now gone). The current format allows superb search facilities, customisation by Registered members, plus is quick ‘n’ easy to update.
Diligently put together in the UK by Alex Kemp. All efforts have been taken to ensure the veracity of what is written - if you know of any errors or omissions then please let us know.
