There are other SCTP features that are used. The most essential is the SCTP multi stream feature, which allows multiple data channels using a single SCTP associations: each data channel is implemented using two unidirectional SCTP streams.

SCTP also provide different options when it comes to data transport reliability and ordering, and data channels can use different combinations.
