- The ‘Smart’ within the name refers to the Smart-DAA with which this chipset was designed to work from it’s inception on 7 June 1999.
A new combo datapump-controller chip--the CX81300--was introduced on 4 June 2002 (replacing the L2800-38 + P9373-11), together with a replacement SmartDAA2 chip--the CX20463-11. In addition, the ISA PnP plus on-board hardware support for DSVD options were dropped.
On 5 August 2003 the DAA was updated to a SmartDAA3 chip--the CX20493-21--and the Voice chip to a CX20442-11. The modem was now stated to fully support V.92 with MOH. In the middle of all of the above, the modem was re-positioned for use within embedded applications such as POS Terminals, Set-Top Boxes, Video Recorders, Metering, Security & Remote Site Management, although it has always had V.34 & V32bis chipset-options in addition to (the original) V.90 + K56flex.
Because of the above history, there are a vast number of different chips which can appear as part of this chipset. What follows below is a discussion of the chipset as part of a ‘traditional’ dial-up modem.
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.92, V.90 or K56flex connection--looks like this (new to old):
This & the SC56D chipset tend to share the same EEPROM ID, and manufacturers tend to leave that to be the same as the SmartSCM.
- SC56D - 06827-xx
- SmartACF - P9373-xx (later 81300-xx)
- SmartSCM - P2106-xx (embedded)
- Rockwell -> Conexant
- RC56D2 - R6764-6x
The “D” in the names above 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).

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.
