CHAPTER 5: CONVENTIONAL FIXED STATION INTERFACE
INTRODUCTION
The Conventional Fixed Station Interface (CFSI) is the interface between a conventional fi xed station
(base station), and either the RF Subsystem (RFSS) or a Console Subsystem. The RFSS and/or
Console Subsystem are referred to as the host. The fi xed station is connected to a host via either an
Analog Fixed Station Interface (AFSI) or a Digital Fixed Station Interface (DFSI). A host can support
multiple analog and digital fi xed station interfaces. The Console Subsystem is comprised of any type
of console from the telephone-type to software based computer consoles.
Currently, the CFSI is used for voice messages only. The data transfer capability is under
development.
