1 Scope p. 13

The present document provides the protocol details for connecting MCPTT systems to Land Mobile Radio (LMR) systems according to the architectural procedures specified in TS 23.283.

The functional entity that provides connection of MCPTT systems to LMR systems over the external interface is the IWF. The IWF is expected to behave as a peer MCPTT system, as further detailed in clause 5 of the present document. The internal function of the IWF is out of scope of 3GPP.

2 References p. 13
