Quizplus · Accepted Answer

T3 lines have a higher bandwidth compared to T1 lines, which makes them more suitable for connecting regional ISPs to the backbone. They provide a speed of 45 Mbps compared to 1.5 Mbps provided by T1 lines. LAN lines are used within a local area network, while NAPs (network access points) are points where multiple networks interconnect, but they are not used for the primary connection between regional ISPs and the backbone.
