We are the ETSI competence centre on network technologies in current and future networks, with special focus on network interconnection. This includes maintaining and evolving the specifications of the architectures and protocols deployed in fixed networks or used in support of network interconnection, as well as monitoring relevant work on future networks technologies performed outside ETSI and provide guidelines on their applicability to ETSI compliant networks. The committee is also the ETSI’s technical contact point for CEPT/ECC WG NaN (Numbering and Networks).
