The T1P1 J-STD-015 (TIA IS-665) is a 1.9 GHz wideband CDMA personal communications system which was standardized in the USA during 1995. At present, the W-CDMA maximum data rate is specified at 64 kbps which allows G4 facsimile transmission. The W-CDMA is a candidate for wireless local loop (WLL) applications. The WLL requires ISDN compatibility at the air interface. This paper describes an improvement to the W-CDMA data transmission system which provides full 2B+D ISDN (integrated services digital network) capability.
