Extending Reach Beyond CSA Range for xDSL Services | HDSL4 DS-1 Service Modules Extending DS-1 reach while maintaining spectral compatibility with xDSL services poses challenges for service providers. Crosstalk interference between copper pairs in the same bundle limits deployment of popular ADSL services to the Carrier Service Area CSA range of 12kft. Still customers want more bandwidth and more service - while demanding increased reliability and performance. Add-in regulatory concerns in leasing unbundled copper and service providers clearly require a solution that transcends HDSL and HDSL2 technology. Soneplex HiGain HDSL4 from ADC offers both extended range and spectral compatibility with such services as ADSL. The result is cost savings and improved utilization of local loop bandwidth. Benefits Spectral compliance. HDSL4 is the only DS-ltransport technology that is spectrally compatible with ADSL when deployed beyond l2kft on 24 AWG. Extended range without repeaters. HDSL4 extends spectrally compatible DS-1 service beyond CSA range to 16kft on 24 AWG. Extended range with repeaters. With two repeaters HDSL4 extends spectrally compatible DS-1 service range to 46kft on 24 AWG. Cost savings. Fewer repeaters reduce equipment installation and maintenance costs. Improved customer satisfaction. Spectral compliance ensures improved circuit performance and reliability. DC HDSL4 DS-1 Service Modules Description Soneplex HiGain HDSL4 DSL4 DS-1 Service Modules Soneplex HiGain HDSL4 is the latest addition to ADC s industry-leading solutions for DS-1 deployment. Soneplex HiGain HDSL4 is designed for applications that require span lengths beyond Carrier Service Area CSA range of 12kft. Based upon the Spectrum Management SM standard Issue 2 Soneplex HIGain HDSL4 promotes interoperability and spectral compatibility with ADSL and other DSL technologies in the same cable bundle. HDSL4 expands the capabilities of traditional HDSL and HDSL2 deployment offerings. It is the latest high-bit-rate digital subscriber line technology
