General Information
Ambient survived as an independant name for only a few years, and this was their big success.

When Cirrus Logic spun the modem division off (and promptly sold it to intel) Ambient inherited a HaM (“Host Accelerated Modem”) modem in the 562x chipset-family. For whatever reason, they discontinued the latter & produced this Family of chipsets instead.

In contrast to Soft modems, these chipsets contain a DSP (Digital Signal Processer) chip but pass controller functions (AT-Commands, etc.) to the host-computer’s OS. This makes an enormous difference to low speed CPUs (such as the lowly Cyrix-233 that these words are being written on) but is not such an issue for the testosterone-filled speed-freaks that fill computer shops today.

The original modems with these chipsets were limited to V.90 on the Windows-platform, but intel now also supports Linux OSs. Generic V.92 drivers are available for both platforms from the intel website (not easy to find). The protocol is found from the driver version:

  • v4 - V.92/V.44
  • v3 - V.90/K56flex

Extra Info

Known Problems
Take care, as E-Tech provide 3 models of their PCI56AVP V.92 model, with different drivers for the 1st 2 models from the 3rd but identical PCI IDs for all 3. Practical differences boil down to the revision level of the DSP chip (no kidding), with the first two models having a MD5628D-L-A chip, whilst the third has a MD5628D-L-B chip. I have no idea whether this is typical for all modems with this chipset, but suspect it is. Get ready to get down on your knees... (The MD5628D-L-C, BTW, is a 536EP V.92 modem.)

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.
