“Essential facilities” are defined as “facilities of a public telecommunications transport network or service that are: (a) exclusively or predominantly provided by a single or limited number of suppliers; and (b) cannot feasibly be economically or technically substituted in order to provide a service.” “Anticompetitive practices” include in particular “anticompetitive cross-subsidization”, “using information obtained from competitors with anticompetitive results” and “not making available to other services suppliers on a timely basis technical information about essential facilities and commercially relevant information which are necessary for them to provide services”.
Las "prácticas anticompetitivas" comprenden en particular "realizar actividades anticompetitivas de subvención cruzada", "utilizar información obtenida de competidores con resultados anticompetitivos" y "no poner oportunamente a disposición de los demás proveedores de servicios la información técnica sobre las instalaciones esenciales y la información comercialmente pertinente que éstos necesiten para suministrar servicios".
