For additional system description and operation, refer to the applicable manufacture handbook.
SATCOM (IF INSTALLED)
The optional multi-channel Satellite Communications (SATCOM) System is provided for worldwide
voice and data communications over L− band frequencies.
The SATCOM system interfaces with a dedicated antenna sub-system to provide satellite
communications. A minimum of three satellite communications channels are required: two voice
channels and one data channel. One voice channel is dedicated to the flight compartment and
another voice channel is dedicated to the Office In The Sky (OITS) telephone. The data channel is
assigned for either the Airborne Flight Information System (AFIS) or the OITS facsimile or modem.
The factory option consists of a multi-channel SATCOM system and antenna. Components include:
• Satellite data unit (forward avionics bay).
• High power amplifier (vertical stabilizer).
• Radio frequency unit (forward avionics bay).
• High gain antenna (top of vertical stabilizer).
• Cabin communication system interface via handset.
• IRS.
• Airborne data link system.
• Maintenance system through CAIMS.
• PC data and FAX capability.
Satellite Data Unit (SDU)
Provides interface to all airplane avionics and contains the location of the applicable satellites and
rate/frequency translation for two voice communication.
Radio Frequency Unit (RFU)
The RFU provides three additional simultaneous voice communication channels when operated in
conjunction with the SDU.
High Power Amplifier (HPA)
The HPA provides rate/frequency power amplification on the L band signals generated by the
satellite data unit or radio frequency unit to a power level required for transmission to the satellite.

CABIN COMMUNICATION SYSTEM (IF INSTALLED)
The Cabin Communication System (CCS) option provides a private automatic branch exchange
switching network. This network routes voice and data communications to and from up to nine active
devices (handsets/FAXs/modems/data link etc.) in the airplane and provides two air-to-ground
channels. The systems includes connections of basic telephone/telecomputing equipment to UHF
antenna and SATCOM links. In the event a data link device is installed on the airplane, the CCS has
the capability to communicate with the data link device using an internal modem.
The digital radio components consist of: one UHF antenna, duplexer and one airborne radio
telecommunication unit. The CCS plus all customer supplied handsets/FAXs/Modems is known as
the Office-In-The-Sky (OITS).
GF0610_069
The digital handset is located in the flight compartment and has a backlit LCD display and telephone
style keypad used to dial calls and select various options. A credit card reader (for optional billing) is
built into the handset and a two-button increase/decrease volume control (side of handset) is also
installed.
Refer to the Magnastar C-2000 user guide CA1030 for description/function and operation of the
system.
