The ability to transmit facsimilies of original docu- ments over the Public Switched Telephone Network (F'STN) has become widely available. Extending this capa- bility to mobile and portable applications via two-way radio is currently possible but not as widely available. A typical mobile facsimile system is shown in Figures 1 and 2. As shown in Figure 1, a land fax machine is connected to a radio station via a circuit in the PSTN. The radio station can then connect the land fax circuit to a mobile or portable fax machine via a radio frequency carrier. The mobile fax machine is commonly connected to the mobile radio tram- ceiver via an adapter box that acts as a Y connector behvem the transceiver and handset as shown in Figure 1.
