M28945

( DataSheet : www.DataSheet4U.com ) ™ A CONEXANT BUSINESS ZipWirePlus™ G.shdsl Transceiver with Embedded Microprocessor M28945 Complete G.shdsl/HDSL2/SDSL Multi-Rate DSL Solution Multimode Operation The ZipWirePlus single-port multimode DSL solution not only complies with the ITU G.shdsl standard; it also supports the optional enhanced performance asymmetrical PSD (EPAP) modes of operation. In addition, it complies with the ANSI HDSL2 standard (ANSI T1.418) and delivers interoperability with Mindspeed Technologies’™ marketleading ZipWire™ transceivers through operation in 2B1Q multi-rate mode. The 2B1Q mode supports AutoBaud™ for SDSL interoperability, rate optimization and fast connect times. The ZipWirePlus also supports Mindspeed’s proprietary modes (such as 32-PAM, 4.6 Mbps operation) which provides high-speed operation. All of these modes are supported by a single hardware circuit (i.e., one transformer, crystal and hybrid for all modes) and can be configured in real time via software control. timeslots. The UTOPIA level 2 interface provides ATM TClayer processing. The framer automatically extracts and inserts DSL overhead (i.e., EOC, indicator and Z-bits, CRC, sync word, etc.) and passes it on to the embedded microprocessor. All G.shdsl,HDSL2, and SDSL frame formats and EOC messaging protocols are supported, as well as other non-standard SDSL frame formats, including framer bypass mode. > K E Y F E AT U R E S > Single-port CPE solution > Multimode operation > Low ...
