技术文摘：TI公布高度灵敏UR8小区网关架构，撑持所有VDSL2和家庭联网科技

On October 13, heart state apparatus (TI) is announced roll out 5 to use gateway of village of Yu Xinyi acting UR8 (the XDSL solution of RG) . The biggest characteristic of UR8 framework is tall function and high flexibility, the multimedia gateway processor that it includes taller function, but processor of process designing DSL PHY, special VoIP and rich interface, the join that can achieve all ADSL and VDSL2 level supports a variety of domestic network science and technology. Through using UR8, manufacturer can design the RG product of a variety of functions neatly, still be in in order to satisfy domestic network science and technology and service the demand of ceaseless gradual progress. Luo Zhenyuan: VDSL2 market just can take off to 2009 Luo Zhenyuan of manager of sale of network of broadband of ministry of career of semiconductor of TI Asia area says, with the gateway of odd chip village of make a great coup of the generation on TI platform AR7 photograph is compared, UR8 has 5 big change. It is the multimedia gateway processor that UR8 used taller MIPS, can support the tall broadband such as IPTV to apply, and the product that has different rate supplies client choice, realize different design; 2 be UR8 but process designing DSL PHY can support ADSL/2/2+ and VDSL2 level, and AR7 can support ADSL2+ only; 3 it is UR8 framework in added special VoIP processor newly, realized outstanding speech function not only, return the wired or wireless speech that can support 4 passageways at the same time; 4 it is UR8 framework offerred richer port, can offer a broadband to serve for whole family through a variety of domestic network science and technology, include aether net, WiFi and family to insert alliance of multimedia of electric alliance, coaxial cable among them (MoCA) and alliance of domestic line network (the standard that HomePNA) establishs. And the 5th big change is, what differ with AR7 is, UR8 framework does not have front of compositive ADSL imitate. Looked at 5 o'clock from above, UR8 framework stresses tall function and high flexibility, and did not surround WLAN substandard chip compositive come in, still came out schism of ADSL imitate front even. The explanation says Luo Zhenyuan, because the broadband receives science and technology and broadband service and science and technology of domestic couplet net to be in ceaseless gradual progress,this basically is, the client needs a very agile platform, in order to build a product that wants from personal place. After prospective market is mature, TI also will roll out the height that is aimed at special application compositive UR8 product. ADSL and VDSL receive the market to forecast his citing to say, VDSL2 still is in early days phase at present, price is higher, and return existence each other epicene problem, to VDSL2 market just can take off after 2009. In fact, ADSL science and technology also experienced this process. 2000 - 2002, ADSL basically solves each other epicene problem, ever since the market rises quickly, 2003 - 2005, ADSL2+ solved each other epicene problem, growing quickly at present. To satisfy the market demand of this kind of interim, UR8 framework can support ADSL/2/2+ and VDSL2 level, the client can choose different imitate front, the design gives different product. In fact, although UR8 framework just supports XDSL to receive science and technology at present, but the flexibility as a result of UR8 framework, it is used possibly also at Cable, fiber-optic wait for other to receive science and technology. Luo Zhenyuan points out, village gateway of future will be to support a variety of enter receiving science and technology of a variety of science and technology, domestic couplet net and a variety of services (data of broadband speech, broadband, IPTV and high-definition game) wait for general platform, UR8 framework catered to this kind of market to expand demand. The characteristic of UR8 framework is the characteristic that the speech subsystem that tall function and high flexibility are core with VoIP processor also is UR8 platform. Luo Zhenyuan says, of tall function but subsystem of process designing speech makes manufacturer can make full use of the speech with rich TI makes up decoder library and VoIP software Telogy Software, include broadband belt to make up among them decoder, wired with wireless make up bag of decoder and fax and modem relay, data to lose the smallest change and fall the high-quality character such as algorithm of a confusion of voices to ensure outstanding user experiences, every kinds of parts of an apparatus of TI UR8 range of products all supports IP quality to govern a function, be like the PIQUA system of TR-069 and TI. UR8 is the product of gateway of the 8th acting village of TI, before this, the volume of shipment of port of village gateway product of TI exceeded 120 million, the each other that has lead operates sexual expression. Luo Zhenyuan emphasizes saying, UR8 platform developed the AR7 range of products with reliable TI adequately to operate the advantage of sexual level field in patulous each other, use existing product investment in order to help manufacturer, research and development gives each other to operate the new generation with good sex solution of gateway of tall function village.

10月13日，德州仪器(TI)公布推出五款用于新一代UR8小区网关(RG)的xDSL解决方案。UR8架构的最大特点是高性能和高度灵敏性，它包括更高性能的多媒体网关措置器、可编程DSL PHY、专门VoIP措置器以及丰硕的接口，可实现所有ADSL与VDSL2尺度的连贯并撑持多种家庭收集科技。经由过程采用UR8，制造商能够灵敏设计出多种性能的RG产物，以满足家庭收集科技和办事仍在不竭演进的需求。

罗振源：VDSL2市场到2009年才会起飞

TI亚洲区半导体事业部宽带收集营销司理罗振源介绍说，与TI上一代大获顺利的单芯片小区网关平台AR7比拟，UR8有五大转变。一是UR8采用了更高MIPS的多媒体网关措置器，能够撑持IPTV等高宽带应用，而且有分歧速度的产物供给客户选择，实现分歧的设计；二是UR8的可编程DSL PHY能够撑持ADSL/2/2+与VDSL2尺度，而AR7只能够撑持到ADSL2+；三是UR8架构中新增了专门的VoIP措置器，不仅实现了出色的语音性能，还可同时撑持四个通道的有线或无线语音；四是UR8架构供给了更丰硕的接口，可经由过程多种家庭收集科技为整个家庭供给宽带办事，其中包括以太网、WiFi以及家庭插电联盟、同轴电缆多媒体联盟(MoCA)以及家庭电话线收集联盟(HomePNA)拟定的尺度。而第五大转变是，与AR7分歧的是，UR8架构没有集成ADSL模拟前端。

从以上五点看来，UR8架构强调高性能和高度灵敏性，而并没有将WLAN等外围芯片集成进来，甚至还将ADSL模拟前端分立出来了。罗振源诠释说，这主如果因为宽带接入科技和宽带办事以及家庭联网科技都在不竭演进中，客户需要一个很是灵敏的平台，以搭建出本身所需的产物。未来市场成熟后，TI也将推出针对专门应用的高度集成UR8产物。

ADSL和VDSL接入市场猜测

他举例说，VDSL2今朝还处于前期阶段，价位比较高，而且还存在互通性问题，到2009年今后VDSL2市场才会起飞。事实上，ADSL科技也履历了这个过程。2000年-2002年，ADSL首要解决互通性问题，厥后市场敏捷增添，2003年-2005年，ADSL2+解决了互通性问题，今朝正敏捷增添。为了满足这种过渡时代的市场需求，UR8架构能够撑持ADSL/2/2+和VDSL2尺度，客户能够选择分歧的模拟前端，设计出分歧的产物。

事实上，尽管UR8架构今朝只是撑持xDSL接入科技，但因为UR8架构的灵敏性，它也可能用于Cable、光纤等其它接入科技。罗振源指出，未来的小区网关将是撑持多种接入科技、多种家庭联网科技以及多种办事(宽带语音、宽带数据、IPTV和高清游戏)等通用平台，UR8架构迎合了这种市场成长需求。

UR8架构的特点是高性能和高度灵敏性

以VoIP措置器为核心的语音子系统也是UR8平台的特色。罗振源介绍说，高性能的可编程语音子系统使制造商能够充分操纵TI丰硕的语音编解码器库与VoIP软件Telogy Software，其中包括宽频带编解码器、有线与无线编解码器以及传真与调制解调器中继、数据包遗失最小化以及降噪算法等高级特征为了确保出色的用户体验，TI UR8产物系列的每种器件均撑持IP品质治理性能，如TR-069与TI的PIQUA系统。

UR8是TI的第八代小区网关产物，此前，TI的小区网关产物端口出货量超过了1.2亿个，领有超前的互操作性表示。罗振源强调说，UR8平台充分阐扬了TI靠得住的AR7产物系列在扩展互操作性程度方面的劣势，以帮助制造商操纵现有产物投资，研发出互操作性好的新一代高性能小区网关解决方案。
