context: isnât available on the HNB then an IPSEC Tunnel is not required for HMS connection and the following occurs: a. HNB requests DNS (Domain Name Server) for the address of the Factory Set Initial HMSâs URL, using the public DNS server. b. DNS responds with the IP-Addresses of the Initial HMS. 3. If Factory Set IPSec/SeGW information is available on the HNB then an IPSEC Tunnel is required for HMS connection and the following occurs: a. HNB requests DNS (Domain Name Server) for the address of the Factory Set Initial SeGwayâs URL, using the public DNS server. b. DNS responds with the IP-Addresses of the Initial Segway. c. Secure IPSEC Tunnel is established between the HNB and SeGway. d. HNB requests DNS (Domain Name Server) for the address of the Factory Set Initial HMS URL, using the DNS server IP address provided along with IPSec tunnel. e. DNS responses with the IP-Addresses of the Initial HMS. 4. The TR-069 CWMP Session is established towards the Initial HMS. An SSL Connection is
description: The Domain Name System (DNS) translates human-readable domain names into IP addresses, enabling internet communication. In HNB-GW discovery and HMS connection, DNS resolves the IP addresses of the Initial HMS and SeGway.
explanation: DNS is a Service because it provides the functionality of domain name resolution, which is essential for other network functions to operate correctly. The text emphasizes its role in facilitating communication between HNB, SeGway, and HMS by providing their IP addresses.
