In plain words
For the ATM Transport Option in clause 4.1, the specification says "ATM shall be used in the transport network user plane and the transport network control plane according to ITU-T Recommendation I.361 [1]." TS 25.414 specifies user data transport protocols and related signalling protocols to establish user plane transport bearers over the UTRAN Iu interface.

How this page was made
The facts box and the tables come straight from the 3GPP specification archive and CR database as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
