tailieunhanh - Fast, Economical T1 Deployment

HiGain® line units (HLUs) offer the industry’s fastest HDSL deployment by automatically synchronizing the incoming DSX-1 stream and the HiGain remote unit. HiGain also provides extensive diagnostics, including a 4-character real-time display. A typical HiGain system consists of CO components, management components, span equipment and remote side components. The CO side uses an HLU that can be installed on existing CO shelves, ADC’s HiGain managed shelves or HiGain CO shelves. | Fast Economical T1 Deployment HiGain line units HLUs offer the industry s fastest HDSL deployment by automatically synchronizing the incoming DSX-1 stream and the HiGain remote unit.
