The format is as specified in TS 33.401 [52].

L.6.2 USIM-RN Files

L.6.2.1 eF_RNid (Relay Node identifier)

This EF contains the Relay Node identifier the USIM-RN is bound to, see TS 33.401 [52].

An USIM-RN shall contain this file. The content of this file is not intended to be read on UICC-RN interface. It serves as a storage location for the Relay Node identifier to which the UICC is bound. The file content is described for the purpose of Over-The-Air update.

L.6.2.2 EF_SCCmax (maximum value of Secure Channel Counter)

This EF contains the maximum number of transaction allowed with the same Connection SA, when a secure channel is established. When the counter value in TRANSACT DATA command reaches the maximum value, the terminal shall derive new key material using Manage Secure Channel APDU – establish SA – Connection SA, see ETSI TS 102.484 [66].

An USIM with an Application ID in the USIM-RN range shall contain this file.

Identifier: ‘6FEB’		Structure: transparent			Optional
File size: 8 bytes			Update activity: low
Access Conditions: READ ALW UPDATE ADM DEACTIVATE ADM ACTIVATE ADM
Bytes	Description			M/O		Length
8	Secure Channel counter			M		8 byte

NOTE: The value of the Secure channel counter is set at personalisation. It is not intended to be updated or modified as a result of establishing a new Connection SA.
