Question 27C3

A LAN (Local Area Network) port on a Fleet Broadband terminal primarily provides connectivity based on the Internet Protocol (IP) over Ethernet. This means it's designed to carry packet-switched data traffic. ISDN (Integrated Services Digital Network), however, is a circuit-switched digital telephone network technology that uses different physical interfaces and signaling protocols than standard Ethernet/IP. Therefore, a standard LAN port cannot directly connect to or provide service for an ISDN telephone handset. In contrast, options B, C, and D describe typical functions of an IP-based LAN port on such a terminal. It provides the necessary IP connectivity for connecting a computer to configure and troubleshoot the terminal, allows computers to access the internet for browsing, and facilitates the connection of Voice Over IP (VoIP) telephone handsets, which rely on IP for voice communication.
