The '''inter-working function''' ('''IWF''') is a method for interfacing a [[wireless telecommunication]] network with the [[public switched telephone network]] (PSTN). The IWF converts the data transmitted over the air interface into a format suitable for the PSTN.<ref>{{cite web |title=IWF Interworking Function |url=https://www.mpirical.com/glossary/iwf-interworking-function |publisher=Mpirical |access-date=19 February 2023}}</ref>

IWF contains both the hardware and software elements that provide the rate adaptation and [[network protocol|protocol]] conversion between PSTN and the wireless network.

someSome systems require more IWF capability than others, depending on the network which is being connected. The IWF also incorporates a "[[modem]] bank", which may be used when, for example, the [[GSM]] [[Datadata Terminalterminal Equipmentequipment]] (DTE) exchanges data with a land DTE connected via analogue modem

The IWF provides the function to enable the GSM system to interface with the various
