Refers to a physical or logical telecommunication connection, such as a telephone line, internet circuit, or data link.
The telephone lines are busy.
I signed up for a new fiber-optic line.
No matter how many times I call, the line won't connect.
Right after the earthquake, the phone lines were congested.
Please cut the line once the call is finished.
After switching to fiber optic, the line got much faster.
