4 Data Link Layer Word‑p. 8

ATM shall be used in the transport network user plane and the transport network control plane according to ITU-T Recommendation I.361 [1]. The structure of the cell header used in the UTRAN Iu interface is the cell header format and encoding at NNI (see figure 3/I.361).

4.2 IP Transport Option |R5|

An RNC/CN-node supporting IP transport option on the Iu interface shall support PPP protocol with HDLC framing (IETF RFC 1661 [25], IETF RFC 1662 [26]).

An RNC/CN-node supporting IP transport option on the Iu interface and having interfaces connected via low bandwidth PPP links like E1/T1/J1 shall also support IP Header Compression (IETF RFC 2507 [27]) and the PPP extensions ML/MC-PPP (IETF RFC 1990 [28], IETF RFC 2686 [29]). In this case the negotiation of header compression (IETF RFC 2507 [27]) over PPP shall be performed via IETF RFC 2509 [30].
