FCC ID: CDG-ARTU
MAGNASTAR
EXHIBITC
C-2000 DIGITAL AIRBORNE TELEPHONE SYSTEM
~: The CAS provides ten switches to control call alerting devices (supplied by the installer) such as
bells, lights, cabin chime, etc. (Even in the relatively noise-quieted cabins of business jets, the ambient
noise can make it difficult to hear the electronic ringer of the standard handset. Increasing the volume of
the handset speaker could be annoying should the handset be close to a user's ear when it rang. A separate
alerter avoids this problem and allows for installation of the handsets in enclosed compartments.) Single or
multiple switches can be assigned to a handset and to multiple handsets; and the cadence of the "ring"
pattern can be controlled, giving a great deal of flexibility to customize uplink call notification. One CAS
is used per aircraft; it connects to a digital handset port of any of the CDBRs in the system. The CAS may
also be used to signal when Air-Ground, SA TCOM or HF services are available or when one or more
particular handsets are in use.
Miscellaneous: The MagnaStar system can interface to many other communications equipment. The
"-802" modification to the ARTU provides a CEPT -EI interface to connect directly to SA TCOM systems
or to cabin management equipment. The flexibility is built in to the system to accommodate customer-
unique requirements with minimum new development.

Installation Summary
The ARTU is installed in an ARINC style mounting tray using two type A hold downs. It is
designed for installation in pressurized or non-pressurized locations. The mounting tray provides an
air plenum and fan for cooling. The fan is quiet enough to allow cabin installation. The duplexer
can be mounted in any convenient location between the ARTU and the antenna. The antenna comes
with a standard six hole mounting flange. As an option, a four hole flange is available for direct
replacement of standard 450 MHz radio telephone antennas. The handsets are designed for
installation in any convenient area of the cabin. Custom mounting provisions can be readily
provided.
Installation information and equipment outline drawings are available in the Interface Control
Document (ICD) Appendix B.
