(Main)Conducted transmission networks -- Part 2: Coaxial cables (CaTV-based)
Conducted transmission networks -- Part 2: Coaxial cables (CaTV-based)
This EMC standard specifies limits and methods of measurement for emissions originating from within traditional telecommunication networks and the immunity of those networks, including their in-premises extensions by references to harmonised product standards in combination with good engineering practice, when installed and operated as intended. This standard covers the frequency range 9 kHz to 400 GHz. To date, it specifies limits and methods of measurement for conducted and radiated disturbances from telecommunication networks in the frequency range 150 kHz to 6 GHz. The assessment of a network needs to be performed only in the frequency ranges where limits are defined. The emission limits set in this standard do not apply to the wanted emissions from embedded radio links within the network. The requirements have been selected so as to ensure that electromagnetic disturbances generated by a network, or parts thereof, operating normally do not exceed a level that could prevent other equipment from operating as intended. Fault conditions of the network are not taken into account.
EMV-Norm für Übertragungsnetze - Teil 2: Leitungsgebundene Übertragungsnetze, die Koaxialkabel nutzen
Norme CEM pour les réseaux de télécommunications - Partie 2: Réseaux de télécommunications filaires utilisant des câbles coaxiaux
La présente norme CEM spécifie les exigences pour les émissions émanant de l'intérieur des réseaux de télécommunications filaires utilisant des câbles coaxiaux et l'immunité de ces réseaux, y compris leurs extensions dans les locaux par des références à des normes de produits CEM harmonisées et à d'autres normes comportant des exigences CEM en combinaison avec les règles de l'art, lorsqu'ils sont installés et mis en fonctionnement comme prévu. La présente norme couvre la bande de fréquences comprises entre 9 kHz et 400 GHz. Il n'est nécessaire d'évaluer un réseau que dans les bandes de fréquences où les limites sont définies. Les limites d'émission fixées dans la présente norme ne s'appliquent pas aux émissions désirées provenant de liaisons radio intégrées au sein du réseau. Les exigences ont été sélectionnées de manière à assurer que les perturbations électromagnétiques engendrées par un réseau, ou des parties de celui-ci, fonctionnant normalement n'excéderont pas un niveau au-dessus duquel des appareils de radiocommunications ou de télécommunications ou autres appareils ne pourront pas fonctionner comme prévu. Les états de pannes du réseau ne sont pas pris en compte.
Prenosna omrežja z vodniki - 2. del: Koaksialni kabli (izhodišče: kabelska TV)
Ta standard o elektromagnetni združljivosti določa mejne vrednosti in metode merjenja za emisije, ki izvirajo iz tradicionalnih telekomunikacijskih omrežij, in odpornost teh omrežij, vključno z njihovimi priključki v prostoru, s sklicevanjem na usklajene standarde o proizvodih v kombinaciji z dobro inženirsko prakso, kadar so nameščena in delujejo, kot je predvideno. Ta standard zajema frekvenčni razpon od 9 kHz do 400 GHz. Trenutno določa mejne vrednosti in metode merjenja za vodene in oddajane motnje iz telekomunikacijskih omrežij v frekvenčnem razponu od 150 kHz do 6 GHz. Ocenjevanje omrežja mora biti izvedeno samo v frekvenčnih razponih, kjer so opredeljene omejitve. Mejne vrednosti emisij, postavljene v tem standardu, ne veljajo za želene emisije iz vdelanih radijskih povezav v omrežju. Zahteve so bile izbrane tako, da zagotovijo, da elektromagnetne motnje, ki jih ustvarja omrežje ali njegovi deli ob običajnem delovanju, ne presežejo stopnje, nad katero druga oprema ne more delovati, kot je predvideno. Okoliščine okvare omrežja niso upoštevane.

Introduction
This part of the multi-part EMC standard specifies limits and methods of measurement for emissions
emanating from wire-line telecommunication networks and immunity of those networks by means of
references to harmonised product standards in combination with good engineering practice. This
standard specifically refers to networks using coaxial cables.

1 Scope
This EMC standard specifies requirements for emissions originating from within wire-line
telecommunication networks using coaxial cables and the immunity of those networks, including their in-
premises extensions by references to harmonised EMC product standards and other standards with EMC
requirements in combination with good engineering practice, when installed and operated as intended.
This standard covers the frequency range 9 kHz to 400 GHz. The assessment of a network needs to be
performed only in the frequency ranges where limits are defined.
The emission limits set in this standard do not apply to the wanted emissions from embedded radio links
within the network.
The requirements have been selected so as to ensure that electromagnetic disturbances generated by a
network, or parts thereof, operating normally do not exceed a level above which radio and
telecommunications apparatus or other apparatus cannot operate as intended. Fault conditions of the
network are not taken into account.
