clearly indicate that there is more than one popular frame synchronization technique |

If the transmission is temporarily interrupted, or a [[bit slip]] event occurs, the receiver must re-synchronize.▼
The transmitter and the receiver must agree ahead of time on which frame synchronization scheme they will use.
The most common frame synchronization schemes are:
=== framing bit ===
A common practice in [[telecommunication]]s, for example in [[T-carrier]], is to insert, in a dedicated [[time slot]] within the frame, a noninformation bit or '''framing bit''' that is used for the actual [[synchronization]] of the incoming data with the receiver. In a bit stream, framing bits are used in determining the beginning or end of a frame. They occur at specified positions in the frame, do not carry information, and are usually repetitive.
=== syncword framing ===
▲If the transmission is temporarily interrupted, or a [[bit slip]] event occurs, the receiver must re-synchronize.
Some systems use a special [[syncword]] at the beginning of every frame.
=== CRC-based framing ===
Some telecommunications hardware uses [[CRC-based framing]].
