ADC’s HiGain® HDSL2 modules enable networks to operate even more efficiently and at lower temperatures than the current technology allows. Power consumption and heat dissipation is reduced by more than 30 percent, enabling service provider’s to avoid or defer capital expenditure additions to existing plants. By providing full-rate T1 access using just a single copper pair, HDSL2 enables service providers to quickly and cost-effectively meet the demand for more voice and data services – services that have become increasingly hard to deliver due to the shortage of copper cable | HiGain HDSL2 Modules ADC s HiGain HDSL2 modules enable networks to operate even more efficiently and at lower temperatures than the current technology allows. Power consumption and heat dissipation is reduced by more than 30 percent enabling service provider s to avoid or defer capital expenditure additions to existing plants. By providing full-rate T1 access using just a single copper pair HDSL2 enables service providers to quickly and cost-effectively meet the demand for more voice and data services - services that have become increasingly hard to deliver due to the shortage of copper cable. HiGain uses ADC s industry-first HDSL2 chipset ANSI compliant that is based on the standard that ADC helped define. More importantly HiGain takes full advantage of the open architecture inherent in HDSL2 delivering guaranteed interoperability allowing you to simply and economically accommodate network growth. Features 30 percent lower power consumption and heat dissipation reduces costs and increases network reliability Full-rate T1 over a single copper pair means that you can cost-effectively meet today s demand for voice data and video services Industry-standard interoperability results in cost-effective implementation and network expansion The capability to reach 12 000 ft on 24 AWG gives you the ability to provide service to more customers Specifications HDSL2 Transmission Line Code Mbps OPTIS Overlapped PAM Transmission with Interlocking Spectra Transmission full duplex Media one non-loaded metallic two-wire cable pair Output Signal CO side from 0-450kHz into 135 d RT side from 0-350kHz into 135 Impedance 135 d Max.
