- 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. IWF contains both the hardware and software elements that provide the rate adaptation and protocol conversion between 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 variousforms of public and private data networks currently available.The basic features of the IWF are:
* Data rate adaption
* Protocol conversion
* v
* t
* e (en)
- 互通功能（Inter-working Function、簡稱：IWF），全名為以太网多业务互通（Ethernet multi-service interworking）。是指在公共交换电话网中，通过MPLS PW链接不同介质AC（Attachment Circuit）链路（二层）的功能。例如，用MPLS PW链接ATM AC和Ethernet AC。 在MPLS论坛(IP/MPLS Forum)2006年输出的《Multi-Service Interworking》文档（论坛文档号MFAForum12.0.0）中有对该功能的定义和各类场景的详细描述。 大致场景包括以下三类： 1.
* ATM or FR or PPP to Ethernet 2.
* ATM to FR 3.
* ATM or FR to PPP 在不同的应用场景下，PW两侧的PE要做的报文封装工作（除PW/MPLS封装以外）及对应的标准（RFC文档）各有不同，现列举如下： AC-1 PE-1 PE-2 AC-2 1 Ethernet N/A RFC 2684-B ATM 2 Ethernet N/A RFC 2427-B FR 3 Ethernet N/A RFC 2878 PPP/HDLC 4 FR RFC 2427-B RFC 2684-B ATM 5 FR RFC 2427-B RFC 2878 PPP/HDLC 6 ATM RFC 2684-B RFC 2878 PPP/HDLC (zh)
