What is IWF (Interworking Function)?

The IWF changes over the information communicated over the air interface into a configuration appropriate for the PSTN. IWF has both the equipment and programming components that give the rate transformation and convention change among PSTN and the remote network. The IWF gives the function to empower the GSM framework to interface with the different types of public and private data networks currently accessible. An IWF guarantees that old and new organization components can coordinate and associate consistently with one another.
