GB/T 2099的本部分规定了家用和类似用途的信息插座的标志、防触电保护、结构、电气性能、机械性能等技术要求。本部分适用于户内或户外使用的、家用和类似用途的、用于连接互联网和传输信息的固定式插座或移动式插座。信息插座适合在下述环境温度中使用:通常不超过+40 ℃,但在24 h期间内平均不超过+35 ℃,环境空气温度的下限值为-5 ℃。
本标准规定了有线电视系统射频同轴连接器(5MHz~1000MHz)的技术要求和测量方法。对于能够确保同样测量不确定度的任何等效方法也可以采用。有争议时应以本标准为准。 本标准适用于有线电视系统用射频同轴连接器(5MHz~1000MHz)的研发、生产、验收和应用。
This Annex B defines the radio-frequency interface specification for high-speed data-over-cable systems. There are differences in the cable spectrum planning practices adopted for different networks in theworld. Therefore two options for physical layer
The present Recommendation defines the radio-frequency interface specifications for highspeed data-over-cable systems.
This Recommendation defines the second generation ofradio-frequency interface specifications for high-speed data-over-cable systems.
The DOCSIS Rec. J.112 and [ITU-T J.122] define the requirements for the two fundamental components that comprise a high-speed data-over-cable system: the cable modem (CM) and thecable modem termination system (CMTS).
This Recommendation defines the physical layer requirements aspart of a series of Recommendations that define the third generation of high-speed data-over-cable system. Thisdocument defines physical layer requirements that support the channel bonding operations defined in J.222.2.
This standard gives guidance on writing the technical specification for the procurement of equipment for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide.
