Busy line interrupt
Busy line interrupt, also known as emergency breakthrough, is a function on land line telephones that allows a caller to interrupt a phone conversation of another caller, especially one who does not have call waiting. Much like long distance calling before the late 90s, busy line interrupt is a service provided, for instance, to allow people to contact a family member in the event of an emergency if the receiving party's line is busy and the news cannot wait.
