Abstract
Abstract A new data circuit equipment (DCE) coupled to an IWF and a terminal adapter (TA) coupled to a mobile station provide interconnection within a RF communication system such that Class 2 service common to wireline network equipment can be beneficially employed in the wireless RF communication system. The new DCE and TA are transparent to external wireline systems while maintaining compatibility with, inter alia, the predetermined data service protocol layers of the RF communication system, the RF air-interface and/or radio link protocol (RLP) of the RF communication system.
