Telecommunications accessibility guidelines for older persons and persons with disabilities Study Group 16
This Recommendation outlines minimum requirements for timing devices used as node clocks insynchronization networks. The requirements relate to fi-equency deviation; pull-in, hold-in and pullout range; noise generation, tolerance and transfer; transient
In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
Protection of Customer Premises from Overvoltages Study Group 5
This Recommendation provides bonding configurations and earthing for telecommunication equipment installed inside differentbuildings in the following cases: buildings with different earthing and power feeding conditions; buildings with the same earthing and power feeding conditions.
This Recommendation considers continuous electromagnetic phenomena from 9 - 150 kHz.Impulsive low frequency phenomena are considered in other K-series Recommendations.Continuous phenomena above 150 kHz are covered by Recommendation K.48 [1].Both the emissions and the immunity to induced signals at frequencies from 9 - 150 kHz are takeninto account in this Recommendation.This Recommendation defines test setup, measurement methods, emission limits and immunity testlevels for telecommunication network equipment.This Recommendation applies to all types of telecommunications network equipment. Due to thenature of the interference, the immunity test is applicable only to equipment having analogue voiceinterface that could be influenced by disturbing signals in the voice frequency range.
This Recommendation gives guidance on the protection of telecommunication centre equipment, such as switching, transmission, radio, and power, from damage and disruption due to a high altitude electromagnetic pulse (HEMP).
