The '''Interinter-working Functionfunction''' ('''IWF''') is a method for interfacing a [[wireless telecommunication]] network with the [[Publicpublic Switchedswitched Telephonetelephone Network|PSTNnetwork]] (PSTN). The IWF converts the data transmitted over the air interface in tointo a format suitable for the [[PublicPSTN.<ref>{{cite Switchedweb Telephone|title=IWF Interworking Function Network|PSTN]]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 [[Public Switched Telephone Network|PSTN]] and the wireless network.

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 in to a format suitable for the [[Public Switched Telephone Network|PSTN]].

Some 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]] [[data terminal equipment]] (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

forms of public and private data networks currently available.

The basic features of the IWF are:

* Data rate adaption

* Protocol conversion
