Line 4: {{Uncategorized\|date=May 2007}} The '''Inter-working Function''' (IWF) is a method for interfacing a wireless telecommunication network with the [[PSTN\|Public Switched Telephone Network]]. The IWF converts the data transmitted over the air interface in to a format suitable for the [[PSTN\|Public Switched Telephone Network]]. IWF contains both the hardware and software elements that provide the rate adaptation and protocol conversion between a landline destination [[Public Switched Telephone Network]] (PSTN) and the network for both data and [[fax]] services. The IWF is required as a network element to support circuit switched data.
