  SMART HSF

The ConexantTM SmartHSF Host-Processed (SoftK56TM) V.90/K56flex Modem Device Family with SmartDAA technology supports analogue data up to 56 kbps, analogue fax to 14.4 kbps, telephone answering machine (TAM), voice/speakerphone (optional), and PCI Bus/MiniPCI/CardBus host interface operation. These modem devices meet the size and power requirements of the mobile environment.

The modem operates with PSTN telephone lines in the U.S./Japan/Canada and optionally world-wide, and with Japanese PDC (Personal Digital Cellular) phones. Modem and cellular data protocol software is provided.

Conexant's SmartDAA technology (patent pending) eliminates the need for a costly line transformer, relays, and opto-isolators typically used in discrete DAA (Data Access Arrangement) implementations. The SmartDAA architecture also simplifies product implementation by eliminating the need for country-specific board configurations enabling world-wide homologation of a single modem board design.

The SmartDAA system-powered DAA operates reliably without drawing power from the line, unlike line-powered DAAs which operate poorly when line current is insufficient due to long lines or poor line conditions. Enhanced features, such as monitoring of local extension status without going off-hook, are also supported.

Incorporating Conexant’s proprietary Digital Isolation Barrier (DIB) design (patent pending) and other innovative DAA features, such as Digital PBX line protection and reporting, the SmartDAA architecture simplifies application design, minimises layout area, and reduces component cost.

For over a decade, Conexant has assisted customers with DAA technology and homologation.

The SmartHSF device set, consisting of a Host Side Device (HSD) in a 100-pin TQFP and a Line Side Device (LSD) (SmartDAA device) in a 32-pin TQFP, supports data/fax/TAM operation with host software-based digital signal processing and cell phone/DAA/telephone line interface functions. The optional Voice Codec (VC), in a 32-pin TQFP, supports voice/full-duplex speakerphone (FDSP) operation with interfaces to a microphone, speaker, and telephone handset/headset.

  SmartMC™& AC-Link Modems

Conexant Offers a Family of AC-Link Modem and Audio/Modems to Support Mobile and Desktop Applications
Conexant’s SmartMCTM and SmartAMCTM system solutions provide the lowest system costs, improved time to market and enhanced features and performance. The product family includes all the necessary hardware and software (algorithms and drivers) required to support modem-only or audio/modem solutions. The Conexant AC-Link system solutions support a wide range of architectures including PCI card or Mini PCI designs, digital controllers or core logic solutions incorporating digital audio and modem support.

Motherboard designs include desktop solutions using the advanced communications riser (ACR), audio modem riser (AMR) or communications network riser (CNR) connectors, and notebook designs using the mobile daughter card (MDC) or Mini PCI connector, or custom form factors. Conexant played an important role in the definition of the AMR and MDC specifications and has helped define the majority of core logic solutions introduced on the market.

Motherboard configurations using the ACR, AMR, CNR, MDC or mini PCI architectures simplify the modem homologation process by allowing the card to be certified independent of the actual system motherboard design. These architectures also support the ability to remove all analogue circuitry from the motherboard, leading to higher-quality audio and reduced motherboard complexity.

The SmartMC and SmartAMC system solutions meet the PC 99 System Design Guide specifications, offering significant benefits such as better overall system performance and standards based power-management support.
These solutions provide all the features of Conexant’s industry-leading SoftK56TM software modem. The communications control code for the SmartMC and SmartAMC are also equivalent to other Conexant modem products. This common control code allows OEMs that have already tested the HSF modem with their standard applications to move quickly into production with the Smart MC and SmartAMC. In addition to standard modem features, both chipsets offer Caller ID, enabling users to identify the source of incoming calls. The chipsets also feature Wake-On-Ring functionality, allowing PCs in a low-power, suspended state to automatically turn back on after receiving a phone call. This unique feature enables PCs to receive incoming messages that they would otherwise miss. Conexant’s modem codec fully supports Intel’s AC 97 version 2.1 specification, designed to help PC manufacturers adopt new modem technologies more quickly and cost-effectively. Conexant collaborated with Intel to develop this specification, and contributed key modem technology.

Because the modems are software based, they can be upgraded for value-added features such as standards, simply by downloading the appropriate drivers.

SmartMC
SmartMC is Conexant’s first product to incorporate our patented SmartDAATM technology, which enables modems and other communications devices to be programmed for use on any public phone network worldwide. The SmartMC modem codec device set supports analogue data communications at up to 56 kbps, analogue fax at 14.4 kbps, and voice/remote telephone answering machine (TAM). SmartMC also supports AC-Link (AV 97) operation for ACR, AMR and CNR interface and MDC and Mini PCI applications. Enhanced features such as monitoring of local extension status without going off-hook are also supported. The device set consists of a host side device (HSD) in a 48-pin TQFP, and a line side device (LSD) in a 32-pin TQFP.

  ModemXpert

Today, most users buy computers primarily so they can connect to the Internet. More PCs feature internal modems, such as Conexant’s industry-leading controllerless and software modems, so that users can go online as soon as they take their systems out of the box.

Going online is usually a painless process, but can be difficult, especially for novice users. And finding the cause of a problem is a challenge in itself, since it may lie with the PC, the modem, the telephone line or the Internet service provider. Users having problems getting onto the Internet call their PC OEMs for support, which at £10 to £16 per call, directly subtracts from the OEM’s bottom line. (In fact, Internet connection problems will account for an increasing percentage of support calls - and the cost of those calls continues to rise.) Sufficiently frustrated users may even return their PCs, resulting in lost sales.
To help your end-users make the most of their Web experience, Conexant introduces ModemXpert, part of the V.Next family of modem features. This innovative application helps users troubleshoot any problems they experience connecting to the Internet with Conexant modems.

An Automatic Assistant
Diagnostic programs are usually designed by third-party companies. As a result, they are often generic, addressing only the most common modem features and issues. But ModemXpert was designed by Conexant. With more than 30 years of modem experience, we are able to anticipate the kinds of difficulties that your end-users may encounter. In fact, ModemXpert is the most powerful diagnostic program in the industry because it is actually part of the modem software driver design. As a result ModemXpert addresses such common problems and complaints as, No dial tone, Low throughput, No connects, Dropped connects.

It will also allow for accurate hardware tests prior to a false return (and the associated costs) of a functional modem. This Windows-based program is not only comprehensive; it is also easy to use. In fact, it’s automatic. When ModemXpert detects a connection problem, it pops up instantly to help users resolve the problem. Furthermore, the program is intuitive, so it helps even novice users establish or regain their Internet connections. Giving users the assistance they need when they need it.

Growing your Bottom Line
Because ModemXpert detects and solves Internet-connection problems automatically, it reduces the need for users to call you for technical support. And even if users do decide to call you, this valuable product can help them describe their problems more accurately to your support representatives, resulting in faster and more accurate service. In either case, ModemXpert increases customer satisfaction and helps you minimise your post-sale support costs. In addition, because satisfied users are more likely to keep the computers they buy, ModemXpert minimises returns - in particular, those due to falsely perceived modem malfunctions. This low-cost solution greatly enhances the value of the modem and, thus the PC. In the process, it increases customer satisfaction and builds your bottom line.
