Realtek and Legerity Announce High-Definition Audio Solution for Phone-Ready PCs; Solution Provides Traditional Phone Connectivity for Next-Generation PC Motherboards.TAIPEI, Taiwan -- Realtek Semiconductor Corp. and Legerity, Inc., the "V" in VoIP(TM), today announced a turnkey Phone-Ready PC solution that combines a high-performance 7.1+2 channel High Definition Audio Codec (1) A hardware circuit that converts analog voice into PCM or ADPCM digital code and vice versa. The term may refer to only the A/D and D/A conversion, or it may include the compression technique for further reducing the signal (definition #2 below). See sampling and codec. with a high-voltage ringing SLIC SLIC Subscriber Line Interface Circuit SLIC Scottish Library and Information Council SLIC System Licensed Internal Code SLIC Subscriber Line Interface Card SLIC Session Layer Interface Card (Alacritech, Inc. for VoIP applications. The Phone-Ready PC provides a convenient and economic solution for user-friendly VoIP by supporting phone connectivity. The solution enables PC vendors to market new platforms that offer extended communications capabilities to consumers, as well as small to medium businesses (SMBs). New users simply plug their current phone into a pre-configured VoIP-enabled PC and begin using a VoIP service. A traditional phone can be connected to a PC through a high-voltage voice interface implemented using the Legerity Le9501 SLIC. The Realtek ALC (Assembly Language Coding) A generic term for IBM mainframe assembly languages. 1. ALC - Assembly Language Compiler. 2. ALC - Airline Line Control. 888 Telecom High Definition Audio codec, which can simultaneously support 7.1 sound playback and 2 independent channels of voice, and Windows(R) driver software provide a standard audio interface to the system and support extended calling features. "This is an effective incremental solution for the PC motherboard Please [improve the article] or discuss this issue on the talk page. ," said Brian Jaroszewski, product marketing manager at Legerity. "The addition of a SLIC interface extends the ability of the existing audio codec to support simplified and high-quality VoIP communications and enhanced collaboration in PC systems bundling VoIP applications." Realtek will be demonstrating the solution at the IDF (Intermediate Distribution Frame) A wiring rack located between the MDF (main distribution frame) and the intended end user devices (telephones, routers, PCs, etc.). Cables run from the outside world to the MDF and then to the IDFs. See MDF and wiring rack. Taipei using a Skype connection through a traditional analog phone The original telephone technology, which converts air vibrations into an analogous electrical frequency. Unless a key telephone system, digital PBX or voice over IP (VoIP) is used, most homes and small offices still use analog phones, and the local loop is mostly analog. . The Realtek ALC888 Telecom supports auto-switching from a Skype connection to the traditional PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. in the event of a power failure, and can continue to provide functions and services, e.g., emergency call (911) access. A user has the flexibility to designate a preferred connection at anytime and can conveniently access enhanced calling features, such as call waiting, caller ID A telephone company service that sends the caller's telephone number between the first and second ring of the call. If the calling number is not blocked, the calling number is displayed on the handset or base station of the called party. and conference calling. The Realtek ALC888 Telecom provides 10 DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming). The ALC888 Telecom integrates two stereo ADCs that feature Acoustic Echo Cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. (AEC AEC US Atomic Energy Commission Noun 1. AEC - a former executive agency (from 1946 to 1974) that was responsible for research into atomic energy and its peacetime uses in the United States Atomic Energy Commission ), Beam Forming (BF), and Noise Suppression (NS) technology for an enhanced VoIP experience. The ALC888 Telecom was recently awarded with "Technology Innovation Accelerated Award" for the "Digital Office" platform at IDF Spring 2006, San Francisco. The Legerity VE950 series was introduced in 2004 and is currently shipping into consumer VoIP gateway products such as cable modems and multimedia adaptors. The series consists of SLIC devices optimized for short loop, power sensitive applications and provides the complete set of line interface functionality needed to interface to a subscriber loop. The Le9501 device works directly from the standard power supply voltages available in a PC by leveraging a built-in boost switching power supply Switch´ing power supply n. 1. a device used as part of an electronic device, which transforms electrical current from an AC line circuit to DC for use in electronic devices, and which can use either 110 volt or 220 volt AC line curent. that tracks line voltage, thereby, minimizing power dissipation and reducing costs. The programmable SLIC supports five SLIC device states, including a low power standby state. The high-integration of the Le9501 device results in a dense voice interface design with minimal external components. The turnkey solution offers a high-performance and modular solution for motherboard vendors interested in participating in the Phone-Ready PC market. Ultimately, the new PC will come pre-configured with Voice over IP service allowing consumers to simply plug in their current phone into the new Phone-Ready PC and start using the VoIP service. For additional information, please contact a local Realtek sales contact. The Realtek and Legerity solution will be demonstrated in the Realtek booth #A32 at IDF Taipei starting April 10th in Taiwan. Legerity will be at booth #A30. About Legerity, Inc.
