#### Details

A controlled slip second is a one-second interval containing one or more controlled slips.

A controlled slip is the replication or deletion of the payload bits of a DS1 frame. A controlled slip can occur when there is a difference between the timing of a synchronous receiving terminal and the received signal. A controlled slip does not cause an out-of-frame error.
