Nope...

I’m going to guess you’re probably confusing what the “T-s” and the “R-s” are designating… You’ll see T, R, and R, R1 used to notate the pin-outs. Easy enough to confuse those for “transmit” and “receive” but those names signify Tip, Tip1, Ring, Ring1. A loop-back plug would connect Ring/Tip (the first pair) to Tip1/Ring1 (the second pair.)
