Methods of measurement for equipment used in digital microwave radio transmission systems - Part 2: Measurements on terrestrial radio-relay systems - Section 9: Service channels

Deals with measurements pertaining to the service channels used in digital microwave radio-relay systems. Two basic methods are commonly used for the transmission of service channel signals (that is voice, supervisory and control signals).

Méthodes de mesure applicables au matériel utilisé pour les systèmes de transmission numérique en hyperfréquence - Partie 2: Mesures applicables aux faisceaux hertziens terrestres - Section 9: Voies de service

Il existe deux mesures se rapportant aux voies de service utilisées dans les faisceaux hertziens numériques. Il existe deux méthodes communément employées pour la transmission des signaux de voie de service (signaux vocaux, signaux de surveillance et de commande).
