| Perfectly Designed for FTTx Last Mile Applications PLANET XDL-2420R is a telecom-level, high-performance IP-DSLAM (Digital Subscriber Line Access Multiplexer) with 24-port VDSL2 / ADSL2+ and 2-port Gigabit TP / SFP combo interfaces, and AC plus DC Redundant Power System. The XDL-2420R is fully compliant with ITU-T G.993.2 VDSL2 standard bａnd plan up to profile 30a. It offers maximum download and upload line rate up to 100/100Mbps on the existing twisted pair lines. For ADSL connectivity, the XDL-2420R supports high interoperability and backward compatibility with ATU-R, and ADSL2 / ADSL2+ line mode. It is an ideal CO solution for FTTx last mile applications of broadbａnd access by ISPs and Telecoms. |

| Delivering High-demａnd Service Connectivity for ISP/Triple Play Devices The XDL-2420R provides excellent bandwidth to meet the requirement of the triple play devices for home entertainment and communications. With the capability of 100/100Mbps symmetric data transmission, the XDL-2420R enables many multi-media services to work on the Internet, such as VOD (Video on Demand), Voice over IP, Video phone, IPTV, Internet caching server, distance education, and so on. ADSL2+ Fallback For those ISPs that still provide ADSL broadbａnd service, the XDL-2420R supports transmission rates up to 24Mbps downstream and 3.5Mbps upstream with ADSL 2+ technology. 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. |
| High-speed Broadbａnd Communications for Home Triple Play Application Nowadays, higher speed home broadbａnd connections are in great demand, but most of the last mile solutions in the market are not easily to be deployed or cost very much. The XDL-2420R will be the perfect solution to the last mile deployment for ISP and Telecom service providers as it applies the EoVDSL (Ethernet over VDSL) to providing up to 100Mbps speed transmission capability with the current telephone wire (RJ11), and thus it does not cost too much for re-wiring and can make many multi-media services come true. The XDL-2420R not only gives the excellent bandwidth for the triple-play home entertainment and communications, but also supports ADSL2 / ADSL2+ technology for users to conveniently utilize the current ADSL / ADSL2+ device. |
 |
| VDSL2 in Hotel Deployment The XDL-2420R can support the ISP and Telecom service providers in long-distance network deployment. By Ethernet standard, the length of cable can only reach up to 100 meters, and thus, the Ethernet network cannot meet the requirement when the deployment needs a longer cable. To solve this issue, the XDL-2420R complies with the VDSL2 / ADSL2+ standard where up to 1.4km in cable length through existing phone wires can be supported. Thus, in the Hotel network, for example, the IPTV, Internet and wireless facilities can be installed in each room even though the central office or control room is over 100 meters away. |
