{{main|Modified AMI code}}

For data channels, in order to avoid the need of always setting bit 8 to 1, as described above, other T1 encoding schemes ([[Modified AMI code]]s) ensure regular transitions regardless of the data being carried. In this way, data throughput of 64&nbsp;kbit/s per channel is achieved. [[B8ZS]] is a newer format for North America, where [[HDB3]] is the original line coding type used in Europe and Japan.

A very similar encoding scheme, with the logical positions reversed, is also used and is often referred to as '''pseudoternary encoding'''. This encoding is otherwise identical.
