Explanation
T1 is a dedicated leased-line WAN technology that provides synchronous (equal) upload and download speeds of exactly 1.544 Mbps in both directions. Because it is a dedicated point-to-point circuit, it does not share bandwidth and guarantees symmetrical throughput. ADSL (Asymmetric DSL) is explicitly named 'asymmetric' because download speeds are much higher than upload speeds. Satellite internet is also asymmetric and additionally suffers from high latency. Cable broadband typically provides higher download speeds than upload speeds and is therefore also asymmetric. Symmetrical speeds are critical for businesses that need equal bandwidth for sending and receiving data.
