Question: What type of interfaces are described by the attribute defining the connection between a terminal equipment and the terminating network in a Public Land Mobile Network (PLMN)?
Option 1: Only digital interfaces (e.g., Ethernet, SDH)
Option 2: A mix including V-series (DTE/DCE), X-series, analogue 2/4 wire, and S interface (D+B+B)
Option 3: Exclusively wireless interfaces (e.g., RF, Microwave)
Option 4: Solely packet-switched network interfaces (e.g., IP, MPLS)
Explanation: The correct answer reflects the variety of interface types supported for connection between terminal equipment and the terminating network in a PLMN. These include both analogue and digital interfaces, catering to different terminal equipment capabilities. This mix ensures flexibility and compatibility with various devices, highlighting the PLMN's adaptability in telecom networks.
