CX28985

Preliminary Information This document contains information on a new product. The parametric information, although not fully characterized, is the result of testing initial devices. CX28985 Octal ZipWireMulti G.shdsl Transceiver with Embedded Microprocessor Multi-Mode Operation: G.shdsl+, HDSL2, SDSL, HDSL, and IDSL Distinguishing Features Multimode operation including: The ZipWireMulti DSL solution goes beyond simple compliance with the ITU G.shdsl – ITU G.shdsl including EPAP standard by supporting the optional Enhanced Performance Asymmetrical PSD (EPAP) modes (ITU G.991.2) modes of operation. In addition, it is compliant with the ANSI HDSL2 standard (ANSI – ITU G.handshake (ITU G.994.1) T1.418) and provides interoperability with Conexant’s market-leading ZipWire – HDSL2 (ANSI T1.418) transceivers through operation in 2B1Q multi-rate mode. The 2B1Q mode includes – SDSL/2B1Q (AutoBaud) support of AutoBaud for SDSL interoperability, rate optimization, fast connect times, – HDSL (ITU G.991.1, ETS 101 135 and ANSI TR-28) and standards-based HDSL operation. Furthermore, it operates in IDSL mode for – IDSL (ANSI T1.601) interoperability with Basic Rate ISDN repeaters. The ZipWireMulti also supports – Proprietary/Extended Reach Conexant’s own proprietary modes, such as 32-PAM, 64 kbps, and 3.088 Mbps (ANSI spectrum management for operation, which provide enhanced spectral compatibility, extended subscriber line loop transmission systems) reach, and high-speed operation.
