Symmetric digital subscriber line (SDSL) is a cost-effective alternative to traditional T1 and E1 data services for business applications. SDSL provides symmetric transmission at T1/E1 data rates over one pair of copper telephone wires. Our SDSL chip sets are designed to meet the International Telecommunications Union G.991.1 standard.
SDSL is available in different configurations including HDSL2 which provides symmetric transmission over one pair of copper telephone wires rather than two pairs, and MSDSL or Multi-rate symmetric digital subscriber line which is used to provide cost-effective symmetric transmission over one pair of copper telephone wires at data transmission rates ranging from 144 Kbps to 2.3 Mbps.
XDSL2
Dual Channel SHDSL Chip Set, G2237
The XDSL2 chip set offers unsurpassed functionality and density for SHDSL. GlobeSpan's XDSL2 chip set provides full G.991.2 (G.shdsl) compliance for both single and dual copper pair systems. In addition to powering SHDSL products, XDSL2 designs will benefit from full connectivity to legacy SDSL equipment. The XDSL2 chip sets deliver industry leading performance and interoperability as a result of the underlying architecture and transceiver firmware.DSL equipment suppliers will benefit from GlobeSpan's high density XDSL2 chip set. Leveraging GlobeSpan's experience in fully programmable DSP's and high performance AFE's, designs benefit from GlobeSpan's commitment to ongoing product improvements and functional integration through software changes only.
SHDSL offers superior performance to legacy ISDN and SDSL systems through advanced trellis-coding and spectral efficiency. The benefit of SHDSL's trellis coding is improved overall reach as well as substantially improved performance in the presence of noise. Higher performance translates into more customers reached, resulting in greater revenue potential for service providers. As well as improved performance, SHDSL eliminates the spectral compatibility issues associated with 2B1Q SDSL. SHDSL has been engineered to coexist with ADSL and HDSL2 in the public network binders!
GlobeSpan's XDSL2 SHDSL chip set provides value added features well beyond the scope of existing DSL market segments, enabling system vendors to enter new markets and significantly differentiate their offerings. Examples of such features include IDSL support, provision for rates up to 4.6 Mbps per channel for MTU/MDU applications, and SHDSL 4 wire support on the same hardware platform.
To accelerate OEM time-to-market, GlobeSpan provides fully documented, turnkey transceiver reference designs, development systems, and technical support.

Orion
Orion Dual Channel IDSL Chip Set G2237
The Orion chip set offers unsurpassed functionality and density for IDSL. GlobeSpan's Orion chip set provides ISDN functionality conforming to ANSI T1.601 for interoperability with existing DLC equipment. In addition to powering IDSL products, Orion designs will benefit from full connectivity to legacy SDSL equipment and support for ITU compliant G.SHDSL (G.991.2). The new Orion chip sets deliver industry leading performance and interoperability as a result of the underlying architecture and transceiver firmware.DSL equipment suppliers will benefit from the packaging of GlobeSpan's new high density Orion chip set which offers IDSL functionality in a package that significantly reduces board area and thus lowers system costs for the Central Office (CO) environment. Leveraging GlobeSpan's experience in fully programmable DSP's and high performance AFE's, designs benefit from GlobeSpan's commitment to ongoing product improvements and functional integration through software changes only.
GlobeSpan's IDSL Orion chip set provides value added features well beyond the scope of exist-ing ISDN markets. The consolidation of IDSL functionality with SDSL and SHDSL onto a single reference design allows equipment manufactures to merge designs and reduce manufacturing costs. The ability to provision a DSL service on a per port basis offers system vendors additional cost savings in the area of service turn up and management. Leveraging the Orion Chip set, system vendors will be able to significantly differentiate their offerings. To accelerate OEM time-to-market, GlobeSpan provides fully documented, turnkey transceiver reference designs, development systems, and technical support.
