description An enhanced interworking function (E-IWF) supports a method of direct digital interworking between a radio telecommunications network and standard Internet Protocol (IP) routers. A general purpose interworking function performs speech transcoding and data interworking. A specific translation interworking function translates directly between mobile-specific voice encoding and Voice-over-IP protocols, and between mobile-specific fax encoding and Fax-on-IP protocols. The method provides interworking between cellular protocols in a time division multiple access (TDMA) cellular telecommunications network, and Internet protocols being utilized by an Internet End-System (ES) or fax gateway.
