V.92 Soft Modems
PCl /AC-LlNK/USB
V.92 - The New Standard
V.92 is the new dial-up modem specification from the ITU (International Telecommunications Union) which incorporates exciting new features: * Quick connect * Modem-on-hold * V.44 compression * PCM (high-speed transmission) upstream
TM * NetWaiting.
V.44 compression is a new compression algorithm for faster download of popular HTML content from the Internet achieving downloads about 30% faster for a more pleasant end user experience.
The SmartDAA Architecture
Conexant's proprietary SmartDAA technology eliminates the need for costly relay and opto-isolators typically used in discrete DAA implementations. The SmartDAA provides all of the interface circuitry, off-hook relay, loop current holding, impedance matching and ring detection. It is designed to meet both USA and international line interface requirements, with enough flexibility to meet all worldwide regulatory requirements. The PC Host system-powered (via the PCI and AC-LINK bus) SmartDAA operates reliably without drawing power from the telephone line. Line-powered DAAs operate poorly when the line current is insufficient because of long lines or poor line conditions. SmartDAA delivers a host of features, including: * Call-waiting detection * Extension pickup detection * Line-in-use detection * Remote hang-up detection * European Handset Exclusion SmartDAA technology consists of three components. A system side device (System PCI or AC-LINK interface), a Digital Isolation Barrier (discrete components, high-voltage barrier) and a Line Side Device (CODEC, hybrid, line protection and DC loop).
Quick connect shortens the time to make a connection by remembering ("training") the phone line characteristics and storing them for future use. Typically, the modem "handshake" to make a connection takes from 25 to 27 seconds. Quick connect will cut the handshake time by 50%, averaging 13 seconds for most calls.
Many households use the same phone line for voice and Internet. When a user is browsing the Internet and incoming call either cannot get through or it interrupts the user's connection. Modem-on-hold allows users to receive an incoming call and stay connected to the Internet. Conversely, users can initiate a voice call and still keep their modem connection.
NetWaiting is bundled with the V.92 modem chipset and driver. It offers a host of customizable features that brings full functionality to the modem-on-hold feature.
PCM upstream boosts the data rates between the user and the Internet to reduce upload times for large files and email attachments. A maximum of 48 Kbps upstream rate, a 40% improvement achieved. PCM upstream works particularly well with new equipment such as Internet-connected digital cameras, which primarily upload rather than download information.
The SmartDAA Advantage
As a worldwide modem leader, Conexant has been in a position to investigate many of the most common user problems. The SmartDAA was designed to help solve these problems.
Long Telephone Loops Suffering from Low-Voltage Signals
Modems which draw power from the telephone line often suffer from reduced performance on long telephone loops. The SmartDAA Solution
ModemXpert -- Solving Problems from the Start
Running in the background as a real-time system tray application, ModemXpert automatically detects communication problems and alerts the user. This Windows-based diagnostic program comes as an option with Conexant products and easily guides the user to a quick resolution. Technical support calls are reduced and in many cases avoided altogether. Customer returns are also significantly reduced. ModemXpert enhances the value of the modem by increasing customer satisfaction. Fewer technical support calls and customer returns add dollars to OEM profits.
SmartDAA uses system-wide power, guaranteeing operation on any loop. Thus, low-voltage signals are not negatively impacted by the power needs of the modem.
Power Line and Common Mode Noise
The SmartDAA Solution The use of differential digital interface acts to cancel such noises.
Unwanted Hum Noise on the Telephone Line
Incessant humming plagues the telephone line when the modem is plugged in but not being used. The SmartDAA Solution SmartDAA minimizes the capacitance across the isolation barrier to eliminate hum noise.

Lightning Surges
The modem system is disrupted or damaged due to lightning surges. The SmartDAA Solution SmartDAA designs have been shown to pass with 5KV surge pulses ranging from 2x10 uS to 10x1000 uS, along with added protection from longitudinal surges. Such problems have rarely been an issue for our
