Competent authorities shall, within one week of the request of an undertaking, issue standardised declarations confirming, where applicable, that the undertaking has submitted a notification under Article 12(3). Those declarations shall detail the circumstances under which any undertaking providing electronic communications networks or services under the general authorisation has the right to apply for rights to install facilities, negotiate interconnection, and obtain access or interconnection, in order to facilitate the exercise of those rights, for instance at other levels of government or in relation to other undertakings. Where appropriate, such declarations may also be issued as an automatic reply following the notification referred to in Article 12(3).
