This annex specifies the coding details at the handover interface HI for all data, which may be sent from the operator’s (NO/AN/SP) equipment to the LEMF, across HI.

At the HI2 and HI3 handover interface ports, the following data may be present:

– interface port HI2: IRI;

– interface port HI3: records containing CC.

The detailed coding specification for these types of information is contained in this annex, including sufficient details for a consistent implementation in the operator’s (NO/AN/SP) equipment and the LEMF.
