LSI/Agere MDC Softmodems (Updated 3-Oct-07)
(Previously or also known as Agere/Lucent AMR / AC'97 / HD Audio Soft Modem)

LSI, (formerly Agere and before that Lucent Microelectronics) makes host-signal processor (HSP) chipsets that can be used to make MDC (modem daughter card) modems for desktops with AMR (audio-modem riser) socket, or notebooks with AC'97-compatible or HD-Audio interface (including HD Audio, AMR, CND and CNC) on the motherboard. The Soft Modem can also be made as a PCI, USB or mini-PCI card. The Soft Modem chipset is also known as Scorpio, LU97, CSP1037, SV92P, SV92P2, SV92PP, SV92PL, SV92A3, and SV92U2. PCI versions may use the Mercury (1034C) codec. AC97 modems may also be incorporated in multi-function mini PCI cards.

A single Windows driver (a .sys file) supports all softmodem designs in 32-bit Windows XP and Vista; there are also 64-bit drivers. Entries in .inf files are used to set appropriate options and have PCI ID information to support particular modems based upon the chipset. The actual driver - a .vxd file for Win9x/Me, and a .sys file for WinNT/2k/XP/Vista, is the same for all PCI IDs, so advanced users can install other vendor's updated drivers with edits to the .inf file. V.90 softmodem driver versions are numbered 3.1.x, and V.92 driver versions are numbered 2.1.x. (Note, while the core driver file - .sys - does not vary among AMR & SV92P modems, the .inf files are different and you can't use a PCI driver .inf for the AMR/AC'97/HD Audio or vice-versa.)

As of October 3, 2007, the latest V.92 driver version at Modemsite is 2.1.81, and a generic AC'97/HD Audio driver is available from Modemsite Downloads. These modems will support Modem-on-hold with the 1.78 Modem-on-hold applet available from Modemsite Downloads if you connect to a V.92 ISP that supports modem-on-hold, and you have call-waiting service on your phone line. The most recent drivers at Modemsite support Windows XP and Vista (older drivers will support older operating systems). The original retail version of Windows Vista shipped with a driver (2.1.69) that lacked call progress sounds - this can be fixed by updating the driver. The drivers available from Modemsite are designed to support the modem for data and fax. For voice support, you may need support from the source that supplied your voice modem.

The modem has been bundled with some ACER TRAVELMATE (350, 505 & 520), IBM ThinkPad (1200/1300,A-series & other) machines, Toshiba Tecra 8200, Satellite Pro 4600 and Satellite 2805-S402, HP/Compaq, and Sony Vaio machines. Some of the modems are made by Ambit - but the site does not have any drivers. V.92 drivers will work with older Agere Softmodems sold as V.90 with appropriate .inf files.)

In addition to V.92 drivers, Modemsite Downloads (Premium Access Subscription required) has old V.90 versions of the driver that may work with older versions of the modem chipset:

This modem is a software modem that lacks a digital signal processor: the modem signal processing is carried out by the system processor.

Driver versions for this modem are numbered 3.1.##
Acer's drivers are 3.1.35 and 3.1.41 (from www.acersupport.com), 3.1.48 (from www.acer.it), while IBM gives 3.1.60 for 95/98 and 3.1.66 for Me (for the ThinkPad 1200/1300 from www.pc.ibm.com).

The modem will be identified (ATi3) as Lucent Technologies Soft Modem AMR.

The Win98 driver is LTSM.VXD.
The Win2k & ME driver is LTSM.SYS.

*Note: The file name & size for Win2k & ME drivers from IBM are identical; however, a file compare reveals that the actual contents of the files differ!

Installation Trouble: Windows 2000 - Acer reports the audio driver must be installed before the modem can be detected. See this Acer Technical Article.

Simon in the UK reports using the IBM 3.1.66 driver with an OEM desktop running WinMe. The modem came with version 3.1.27, and increased from only a 14.4k connect to 48k with the upgrade.

Jeff in Starkville reports, and others have confirmed:

I have a TravelMate 507DX (505 series), and my driver (3.1.41) sucked royally.. I'd connect between 21.6k and 24kbps... Anyways, I downloaded the ThinkPad driver off of IBM's site and it did not work.. (it would not recognize the modem). However, with some very minor hacking, I was able to get it to work, and I now connect at 40kbps!!!

Here's the easy to do trick: Download version 3.1.97 from IBM website.. and unzip/install the files to directory of your choice. Next, go to that directory and edit 'LTSMvxd.inf'. Scroll down to the section [Lucent_Modems], and you'll see a line that reads:

%INTEL_AMR.Modem% = INTEL_AMR.Modem, PCIVEN_8086&DEV_7196&SUBSYS_01A21014

Change the end to read:
%INTEL_AMR.Modem% = INTEL_AMR.Modem, PCIVEN_8086&DEV_7196&SUBSYS_100B1025

..then run the modem install program, reboot, and it will install itself. Presto chango, now it makes crazy sounds when I connect, and I get MUCh faster connect speeds! :)

Voytec in Toronto reports - Toshiba drivers work on Acer 506/507 in Windows 2000.

Agere (formerly Lucent) specification sheet on the chipsets in .pdf format used to be available on the Agere site: CSP 1037 and SV92P.
The AT Command Set documentation was on the Agere site. Note the modem supports country selection with the AT%T19 command - using the same parameters as the LT Win chipset - see COUNTRY SELECTION section of this LT Win page.

The APL43 Host-based chipset, will support V.92. Specification sheet was on the Agere site.

Windows XP & AC97 (AMR Modem) with Intel 440MX chipset: See this MS KB Article 306580.

DISTINCTIVE RING: Agere softmodems support distinctive ring as specified in the ITU-T V.253 Recommendation. The modem reports DRON / DROF times, and expects the application software to take appropriate action. CATCH22: Microsoft does not support the V.253 Recommendation: Microsoft KB Q240996 states in part that your modem '...must support true Distinctive Ring, and not DRON/DROF'. This means standard Windows TAPI-compliant applications will not work with Agere's distinctive ring reporting. (Also see: Usenet thread on Lucent Distinctive Ring support.)

V.92 - See V.92 Commands and Modem-on-Hold.

LINUX - Agere does not make a Linux driver available to the public. Agere has made a Linux driver for some Linux distribution packages - the biggest problem appears to be the Free Software Foundation (FSF): a softmodem driver needs to contain proprietary code that would be in hardware (firmware) for a hardware modem. The FSF's license (GPL) requires anyone using any part of Linux code to make all derivative works available for free - Agere is concerned that making a Linux driver available without making the source freely available might result in FSF suing Agere. (FSF has sued a number of companies over such issues.)

However, Olive Essert from Belgium sends feedback to Modemsite indicating that the Linux driver from Smartlink's website (slmodem-2.9.9.tar.gz) works with the Lucent/Agere Scorpio modem that came in a Toshiba notebook. This is possible because the hardware in both Agere's AMR modem and Smartlink's - the silicon DAA - are the same component. (As the softmodem name implies, all modem functions except the physical interface to the computer and phone line are performed outside the modem itself by software running on the PC). And, Gennaro from Italy reports success using the Smartlink Linux driver on Linux Slackware 10.0 (2.4.26) on an Acer Travelmate 740.

If you have any additional information or experience with this modem, please let me know!

LSI/Agere SV92P Soft Modem (Updated 3-Oct-07)

LSI (formerly Agere and beofre that, Lucent Microelectronics) makes a soft modem chipset that enables modem manufacturers to make a PCI or USB software modem. (There is also a version for Notebook computers covered on this page.) The original chip in the series was the same size and format as Agere's 1648C DSP modem chip, and allowed modem manufacturers to build modems using either chip with everything else being exactly the same. The difference is in the drivers: the SV92P relies on your PC's CPU to do digital signal processing, whereas the 1648C does the processing. (Modems with the 1648C are generically referred to as LT Win Modems.) In 2006, a new version of the modem, called SV92PP, was introduced. The SV92PP is functionally the same, but uses a new codec (CSP1040 - nicknamed 'pinball'). Since then, additional versions and improvements have been made in both the hardware (chips) and software (drivers) to further increase reliability and performance and at the same time reducing cost.

The 2.1.81 drivers available from Modemsite Downloads supports most versions of the LSI/Agere/Lucent softmodem in 32-bit Windows XP and Vista, and 64-bit Windows Vista. Older versions of the drivers available at Modemsite may support older/other operating system versions. The original driver supplied with the first retail release of Windows Vista lacks modem-on-hold functionality, and has no call-progress sounds. An updated Vista driver may be available from Microsoft Windows Update that corrects the call progress sound; but, the Modem-on-Hold (MoH) applet (available from Modemsite Downloads) along with call-waiting service from your phone company and a V.92-ISP that supports MoH is required to place your Internet connection on hold while making or receiving another call.

SV92P modems support V.92 and V.44, as well as older V.90/V.42, V.34 and lower protocols.

The modem driver is a major factor in how well the modem will perform. Modemsite's Download Area offers the latest drivers and Modem-on-Hold applets for LSI/Agere/SV92P softmodems. As of 3-Oct-07, the latest generic driver is 2.1.81 for 32-bit Windows XP and Vista, and 64-bit Windows. Older version 2.1.73 supports Windows 2000, XP, and 64-bit XP only, and 2.1.47 for all earlier versions of Windows. The latest Modem-on-Hold applet is version 1.78. (The 2.1.81, 2.1.73 and 2.1.47 Vista/XP/2000 drivers from Modemsite are digitally signed.) The 2.1.47 XP driver is offered in 2 versions: 1 routes call-progress audio to the system audio and is suitable for modems that don't include an onboard speaker; the other version routes call progress audio to the on-board modem speaker.) At times, Microsoft's Windows Update may have a later driver available for Windows 2000 & XP - however, this driver may have V.92 disabled: using the driver from Windows Update will result in loss of all V.92-functionality including the ability to do Modem-on-hold. Unfortunately, this driver has been marked such that users who have Windows Automatic Updates turned on may receive this driver automatically and without notification. The drivers available from Modemsite Downloads do not have V.92 disabled. However, in some cases, without changing Automatic Updates to off, or to notify before installation, the V.92-disabled driver from Windows Update may be automatically re-installed. Users who experience loss of V.92/modem-on-hold functionality should either rollback to the prior driver, or download and install a driver from Modemsite. Then, ensure that the Modemsite driver will not be replaced by setting Automatic Updates (Start->Control Panel->System-> Automatic Updates tab: to Notify me but don't automatically download or install them. Examine each update you are notified about, and Cancel installation of any update for the Agere softmodem.

I've tried modems with the SV92P chipset in a number of machines, including an old 266mhz-PentiumII running Windows NT 4. The added load on the PC's CPU is negligible. I get reliable 50.6k connects to local ISP lines compared to 48-49.3k with USR's Courier and Sportster modems. (All phone line conditions aren't the same, and some lines are 'beyond help' - not 56k-compatible.) I think the Agere Softmodem may be the best softmodem design available today - the load placed on your system in any softmodem design depends largely on how efficient the driver is. The performance (speed) of any softmodem depends largely on how good the driver is as well.

Modems using the SV92P contain the SV92P-T00 or SV92PL-T00 or SV92P2 chip and a discrete codec. The P & PL versions are functionally identical - the PL is newer (lower cost design inside the chip) and is supported with driver versions 2.1.31 and later. The Agere 'Mercury' codec (1034C) uses a line transformer and electro-mechanical or solid-state relay. Agere's 'Levana' (1035A) is a line-powered, transformerless DAA codec. The modem operates with the same driver with all codecs. (In my opinion, modems using the electro-mechanical design are more reliable; however, the solid-state DAA design is less expensive, and providestype-1 caller id. Modems using the electro-mechanical DAA don't support type-1 caller id unless driver version 2.1.40 or higher is used, and the modem was manufactured with components for type-1 caller id. Both designs support type-2 caller id.

Modems based on this chipset are made by a number of manufacturers and sold under various names. The drivers and MoH applet for V.92 are developed by LSI/Agere and made available to the manufacturers. Modemsite's Who Made my Modem page may help you determine your modem manufacturer and locate a driver; or, you can download the latest driver from Modemsite. Driver updates may also be available from Microsoft's Windows Update. LATEST DRIVERS MAY BE NEEDED TO GET BEST PERFORMANCE FROM THIS MODEM! To see what drivers you're using, issue the ATi3 command in Hyperterminal, or, use the Query Modem button in the Diagnostics tab of modem properties (Query Modem available in later versions of Windows only).

AT COMMANDS:
The chipset supports
V.92 Commands
Speed Limit Commands

Protocol - +MS=(options) command.
AT +MS=? from Hyperterminal will display all valid protocol & speed limit option settings

Diagnostics - ATi11 - displays post-call diagnostic information:

Trouble: There were various reports from US & abroad of the modem with solid-state DAA reporting it is connected to a digital line when it really isn't - preventing the modem from going off-hook and dialing. The latest driver will almost always solve the problem. As a last resort, the detection of analog line can be disabled by editing the .inf file, then re-installing the modem. To disable, edit the .inf file (can be located from Modemlog) by removing the comment (semi-colon) from the line in [MONTBLANC_Modem.AddReg] section; save, then re-install modem:

;HKLM,SOFTWAREAgereSoftModem,CodecFlags,1,00,00,00,08

Standby Mode: If you have Quicken software installed, default settings may prevent you from entering standby mode with the PC complaining that the modem driver is preventing the system from entering standby. You'll need to change Quicken's settings to disable background Internet connection.

XP Service Pack 2 / Windows Update: Driver version 2.1.41.10 was added to Microsoft's Windows Update site as a critical update (Oct 04). 2.1.47, and then 2.1.51 were later added to Windows Update. Before the 2.1.47 driver was added, Automatic Updates may have automatically installed the .10 driver which is an HP/Compaq-customized version, and may not be 'the best' driver. Driver version 2.1.47 or 2.1.51 currently are the best/latest drivers and both versions - as well as older driver versions - are available from Modemsite Downloads. Generic OEM modems using the SV92P chipset often have the same PCI ID information as HP/Compaq SV92P modems which can cause HP/Compaq-customized drivers to be installed on other modems.

The SV92P is a good Softmodem: In October 2002, I evaluated a modem using this chipset, and was so impressed that I began selling it. In my opinion, this modem doesn't deserve the 'junk' label often associated with soft modems: in almost all cases, it installs easily, and performs as good as or better than any other 56k modem. (Caveat: modems with SV92P may be designed with an audio transformer and electro-mechanical relay (1034C codec) or with a solid-state line-powered DAA (1035A codec). My experience was that the solid-state design has a much higher chance of being DOA or failing in the field. Modemsite currently sells a modem with this chipset that includes the electro-mechanical relay.

AMR (AC'97) or HD Audio versions of the Agere softmodem are often bundled with notebook computers - and require a different driver package from the PCI modems covered here. The 2.1.81 driver for AC'97/HD Audio Agere Softmodems is available from Modemsite Downloads. Also see: LSI/Agere MDC (AC'97 / HD Audio) page.
