Immunity of home network devices to electromagnetic disturbances
Abstract: The introduction of high-speed data services to customer premises that rapidly adopt new technologies allows the distribution of such data within customer premises. This is leading to a number of different wireless (e.g., ... -
Surge parameters of isolating transformers used in telecommunication devices and equipment
Abstract: Telecommunication devices and equipment can use non-linear limiting, linear attenuating, or both types of functions to mitigate surges occurring on services. Isolating transformers attenuate common-mode voltage surges on ... -
Safety criteria for telecommunication equipment
Abstract: Recommendation ITU-T K.51 provides guidance on safety criteria for telecommunication network infrastructure equipment. It specifies requirements intended to reduce risks of fire, electric shock or injury for specified ... -
Classification of interface for application of standards on resistibility and safety of telecommunication equipment
Abstract: Recommendation ITU-T K.75 provides guidance to manufacturers, network operators and test houses on the classification of the type of interface, i.e., external (subjected to a.c. surges or conducted lightning surges) or ... -
Protection measures for radio base stations sited on power line towers
Abstract: Locating radio base station antennas in power line towers is mainly of interest in rural areas, where there are no tall buildings, where antennas may be installed. At the same time, some precautions have to be taken in ... -
Safe working practices for outside equipment installed in particular environments
Abstract: Recommendation ITU-T K.64 describes working practices for service personnel to help them work safely in telecommunication installations in three specific environments. -
Guidance on complying with limits for human exposure to electromagnetic fields
Abstract: Recommendation ITU-T K.52 aims to help with compliance of telecommunication installations and mobile handsets or other radiating devices used against the head with safety limits for human exposure to electromagnetic fields ... -
Audio-based network navigation system for persons with vision impairment
Abstract: This Recommendation explains how audio-based network navigation systems can be designed to ensure that they are inclusive and meet the needs of persons with visual impairments. The Recommendation adopts a technology neutral ... -
Safe limits for operating voltages and currents of telecommunication systems powered over the network
Abstract: This Recommendation provides guidance on voltages and currents that may safely be used to power telecommunication systems that are part of the telecommunications service providers’ network. These systems use the paired-conductor ... -
Resistibility of telecommunication equipment installed in the access and trunk networks to overvoltages and overcurrents
Abstract: Recommendation ITU-T K.45 specifies resistibility requirements and test procedures for telecommunication equipment installed between telecommunication centres and between a telecommunication centre and the customer's premises. -
