Tech Featuressecurity guarantee, winning praisesfrom officials and experts.As there is an increasing needto deliver high-speed symmetricalbroadband for advanced IPTV services,<strong>ZTE</strong> took the lead in the introductiono f t h e l a t e s t D S L b r o a d b a n dtechnology, called VDSL2.With a support for very-high-bitratedigital subscriber line2 (VDSL2)technology, the <strong>ZTE</strong> NG DSLAMprovides telecom operators withan image transmission monitoringsolution, and the key customer segmentwith a high-speed access solution.The <strong>ZTE</strong> VDSL2 has the followingfeatures:● High-speed transmissionThe <strong>ZTE</strong> VDSL2 can provide100Mbit/s transmission (both up anddown) over a short distance when aspectrum of 30MHz is used.● Remote transmissionThe <strong>ZTE</strong> VDSL2 has a maximumdownlink transmit power of 20.5dBmand can reach a distance of over 2.5kmwhen using an upstream “0” band,echo suppression and time domainequalization techniques.● Various configuration profilesThe <strong>ZTE</strong> VDSL2 has differentprofiles and bandplans targetingdifferent deployment scenarios. Itoperates at a maximum bandwidth of30MHz. For frequency band between1MHZ to 12MHZ, it is based on theexisting 997 and 998 plans includedin ITU-T Recommendation G.993.1.For frequency band between 12MHzand 30MHz, it adopts one or moreupstream and downstream bands tosuit various applications.● Compatible with ADSL/ADSL2+The <strong>ZTE</strong> VDSL2 uses DiscreteMulti Tone (DMT) modulation, amulti-carrier communication system.It supports STM and Packet Modetransmission (PTM) based on theIEEE802.3ah 64/65 byte encapsulation,in addition to the ATM transport usedby ADSL and ADSL2+ networks.● Better support for video servicesTo offer optimal video services, the<strong>ZTE</strong> VDSL2 provides Impulse NoiseProtection (IMP) through the use ofinterleaving. The interleaving depthis dynamically adjusted accordingto varying error codes. Besides, itoffers a dual latency path for a mix oftraffic (especially the video service)that has different packet loss rates andlatencies.FSAP supports evolution to NGN<strong>ZTE</strong> has actively attended standardorganizations such as DSL Forumand established itself as one of the topthree global DSL equipment vendors.The company has a deep understandingof broadband access networks as wellas supporting technologies and futuredevelopment trends.O p e r a t o r s a r e u n d e r g o i n gtremendous business transformation.Critical to this transformation is theintroduction of NG DSLAM whichnot only keeps in line with the networkevolution trend but also sustains longtermdevelopment as it has a strongscalability.T h e Z T E F S A P 9 8 0 0 s e r ve sas a powerful platform to helpoperators build a service-rich accessnetwork. It is a perfect fit for newgeneration communication servicesdue to its advanced architecture andextensibility. Moreover, flexibilityand upgradeability are required forDSLAM as the access network hasa large coverage area and scale.However the <strong>ZTE</strong> FSAP 9800 meetsall these challenges with the best ofbreed of features, allowing operatorsto successfully evolve into a nextgeneration network .14<strong>ZTE</strong> TECHNOLOGIES
