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]].

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.

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

The basic features of the IWF are:

* Data rate adaption

* Protocol conversion
