Tech Featuressecurity guarantee, winning praisesfrom officials and experts.As there is an increasing needto deliver high-speed symmetricalbroadband for advanced IPTV services,ZTE 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 ZTE NG DSLAMprovides telecom operators withan image transmission monitoringsolution, and the key customer segmentwith a high-speed access solution.The ZTE VDSL2 has the followingfeatures:● High-speed transmissionThe ZTE VDSL2 can provide100Mbit/s transmission (both up anddown) over a short distance when aspectrum of 30MHz is used.● Remote transmissionThe ZTE 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 ZTE 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 ZTE 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, theZTE 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 NGNZTE 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 ZTE FSAP 9800 meetsall these challenges with the best ofbreed of features, allowing operatorsto successfully evolve into a nextgeneration network .14ZTE TECHNOLOGIES
