The XDL-2420R supports PPPoE relay to establish connection with ISP, and it is switched over to VDSL2 after the network upgrade.Comprehensive and Advanced VDSL2/ADSL2+ Configuration For the bandwidth and distance of broadband access, the XDL-2420R IP-DSLAM supports multiple selective VDSL2 profiles (8a, 8b, 8c, 8d, 12a, 12b, 17a and 30a), 997/998 band plan and ADSL/ADSL2/ADSL2+ ITU-T G.993.1, ITU-T G.992.3, ITU-T G.992.5, Annex A/B/L/M transmit modes to each subscriber line. Furthermore, it can be configured on a per-link basis for transmission mode, rate limitation, INP (impulse noise protection) and SNR (signal-to-noise) margin. These advanced xDSL functionalities help service providers to adjust the line performance and build a stable and reliable IP-DSLAM solution.Extremely-reliable Design to Ensure Continuous Operation The XDL-2420R supports the SELT (Single-end Loop Testing) and dual power inputs system for continuous network operation. SELT simplifies the testing of a DSL loop from one end to the line to be completed easily from the central office (CO) without having to require a technician or any equipment to be employed at the subscriber site. SELT makes line maintenance easily and reduces device shutdown time. The XDL-2420R is also equipped with one 90~240V AC unit and one DC -48V power supply unit for power redundancy. The Redundant Power System offers more reliability and reduces the possibility of device shutdown. The -48V DC power supply implemented makes the XDL-2420R IP-DSLAM as a telecom level device that can be located at the electronic room. |
