Configuration Files
There are two system configuration files used by ROSS:
ROSS Configuration Files – A factory default configuration file and an active configuration
file holds the parameter values of the ROSS unit, which include parameters such as unit IP
address, ACU address, Modem address, VMS Multicast address and Network Identifier.
The default configure file only sets the factory unit IP address (192.168.254.3/24) leaving
all other parameters un-initialized, zero. Upon initial configuration the active configuration
file is generated and used during normal operations. If the restore factory defaults is
executed the active file is removed and regenerated with default configuration.
Note the password is stored directly to the system account utility (default "Comtech") and
is only configurable through the console Telnet/Serial interface. If the password is lost or
unknown, the password can be restored through the local serial console interface which
does not require a login user name or password. Also factory resetting will restore the
password to default.

Database Files
There are four database files used by the ROSS:
Service Areas (SA) File – This is the primary database that provides critical information
about each satellite with which the local remote will communicate, such as the satellite
orbital position, TX polarization, frequency, bandwidth and identifiable description. These
set of parameters are sent to the ACU upon detected handoff points. The service area is
directly associated to service boundary and modem configuration files, which in
combination construct the communication area.
Shoreline Database File – This file contains the coordinates that comprise the shoreline map.
The SOTM system ensures that satellite transmission is strictly coordinated within a
configurable shoreline threshold expressed in Kilometers. When it is necessary to override
the global shoreline threshold, an override value can be specified in a Coordinated Area.
Coordinated Areas Map (CAM) File – This global database file defines those areas that call
for special transmission requirements. These areas serve as overrides, either negative or
positive, for enabling/disabling the modem transmit function. See section describing the
Ross Configuration Editor for more information on editing coordinated areas.
Service Boundary (SB) File – This file defines the geometry of a service coverage area
within the satellite footprint for the remote. Typically, multiple service boundary files are
stored on the ROSS, each corresponding to either a specific satellite or central hub with a
common satellite coverage area. Handoffs occur between service areas when the boundary
of the current service area is crossed.
Modem Configuration File – This file contains all configuration parameters for the CDM-
570/570L & SLM-5650A base modem and IP Network Processor card. Typically, multiple
modem configuration files are stored on the ROSS, each corresponding to only one service
area location.
