ITU-T G.9701建议书规定了一种千兆宽带接入技术,它利用了现有的线对基础设施,最初是为普通老式电话业务(POTS)服务而部署的。实现本建议书的设备可以从离客户房屋很近的地方(光纤至分发点,FTTdp)或建筑物内(光纤至建筑物,FTTB)开始部署。本建议书支持非对称的和对称的传输,使用高至106 MHz的频谱,在双绞线上,其总的净数据率可高达1 Gbit/s,并规定了所有必要的功能,以支持取消多个线对之间的远端串扰(FEXT),以及促进低功率运行。ITU-T G.9701(2019)建议书集成了ITU-T G.9701(2014)及其所有勘误和修正,并增加了对以下新功能的支持:LPM类、检测序列长度的可选扩展、短CLR/CL消息、附件R – 重新配置显示时间和附录IV – 带有有源ITU-T G.9701支持线路的定向广义矢量化。
它还添加了一些说明,并更正了各种错误和不一致之处,包括ANDEFTR支持、SRA触发和PMS-TC参数要求以及rtx-uc异常的条件。勘误1(2019)包括对第13.2.1.3款的澄清,RPA程序。第1修正案(2019)包括对DTA功能的增强。勘误2(2020)对建议书中的各种错误进行了澄清和更正,特别是在关于协调动态时间分配(cDTA)的附件D中。第2修正案(2020年)包括一个新附件,其内容是涉及不活跃的G.9701辅助线路(TGVN)的目标通用矢量,间隙时间Tg1’范围的可选扩展,cDTA的Mds范围可选扩展,以及RMC载波掩模和用于配置首选净数据速率参数的新附录。第3修正案(2020年)包括支持使用cDTA将Mds的最小值降至5。
