SECTION II. PRINCIPLES OF OPERATION
1.8.
GENERAL OVERVIEW OF SYSTEM OPERATION
Each version of the AN/VIC-3(V), Vehicular Intercommunication System (VIS) is
made up of members of a family of common boxes interconnected by highway
cables in either a ring or two-branch configuration as shown in figure 1-1.
Specific configuration details depend upon the type of vehicle into which the
system is installed. Each system contains one Master Control Station (MCS), up
to six Full Function Crew Stations (FFCS) and one Loudspeaker (LS). Up to four
Monitor Only Stations (MOS) and/or up to two Radio Interface Terminals (RIT)
(if one to four additional radios are being utilized) may also be added. Each
system also contains headsets for each FFCS and MOS in the configuration,
which vary in type depending upon the specific vehicle configuration
requirements. (For specific characteristics of the individual components for the
VIS refer to Section III , Chapter 1) Neither the ring or two-branch configuration
relies on individual units (boxes) to re-transmit data. If any unit within the system
becomes inoperable it does not necessarily interfere with the operation of the
rest of the system. The ring configuration provides additional survivability by an
automatic reconnect feature that changes from the ring configuration to the
two-branch configuration if a highway cable is broken or disconnected.
