Globalstar MCM-4e OPERATION
1
Operation
Your Multi Channel Modem System is easy to use, versatile, and dependable. When configured properly, all
4 channels can be combined to provide an aggregate Internet connection equivalent to a 28 Kbps modem.
If two units are available and configured for cascaded operations you can achieve an aggregate Internet
connection equivalent to a 56 Kbps modem. Internet access is available in all Globalstar™ network data
services coverage areas except those for China and Nicaragua.
WARNING - The transmitted RF field intensity at the surface of the transmitting antenna is
fairly high. Do not use when someone is within 29 inches (0.74 meters) of the antenna.
Basic Satellite Information
Globalstar satellites operate in an inclined orbit of 52 degrees. They come up over a point on the
western horizon, move across the sky, and then drop behind the eastern horizon. The average user
cannot predict the path of the satellites. Each satellite will pass from horizon to horizon in about 10-15
minutes. When the MCM-4e is located in moderate latitudes (22-52 degrees) it will communicate with
at least TWO satellites passing over your geographic location.
This system uses high frequency microwave signals. Unlike television and AM or FM radio signals, or
even cellular phone signals, microwave radio signals do not bend and are strictly line of sight. This
means that these signals do not go through, or around, dense objects including the platform’s own
superstructure, wings or masts. It can not go through, or around, other objects adjacent to the
platform either (trees, buildings, overhangs, cranes, tall hills or mountains). If something gets between
the satellite and the antenna the data connection won’t work until another satellite (which is not
blocked) is received or the platform moves to a location where your antenna will no longer be blocked
by the object. If the antenna is no longer pointed up toward the overhead location of the satellites, the
data connection won’t work until the antenna has a clear view of the sky above again.
If the MCM-4e antenna’s view of the sky above 10oelevation is restricted, the unit will suffer temporary
data rate reductions. If the antenna is completely blocked, the signal to/from the satellite will be lost
until the signal path is unobstructed.
Key Points About Your Equipment
The MCM-4e provides you with data access over the Globalstar satellite network. In some geographic
areas setup, configuration and usage may be slightly different. Subject to certain constraints, the
MCM-4e is capable of dial up packet or asynchronous operation in any Globalstar service area. These
constraints, and the service limitations, are described in Section 2.
The MCM-4e provides the ability to establish up to four concurrent satellite connections each
providing 7.2 Kbps of raw symmetrical bandwidth. The MCM-4e provides the combined bandwidth to
the user via a single standard Ethernet connection. The MCM-4e is a full duplex device and can be
configured to allow other data terminals to initiate a data communications connection. For this
purpose, any of the four SDMs may be configured to receive an incoming asynchronous data call from
a PSTN modem. The MCM-4e unit can be connected to a second MCM-4e unit to provide the
combined bandwidth of up to eight concurrent satellite connections.
The MCM-4e is comprised of two modules: the Antenna and the Multi Channel Modem (MCM-4e).
The Antenna is mounted on an external surface. The MCM-4e contains an ML-IP ePipe 2188 and four

QUALCOMM GSP-1620 Satellite Data Modems (SDM). The MCM-4e also includes a Ethernet 10
Base-T port, power supplies, converters, and management functions.
The 10/100 BaseT Ethernet port can be connected to multiple remote client terminals through a
suitable hub or switch. It provides the path through the Globalstar network for your remote client
terminal(s) to communicate. Your connection may be to a public server site or you may be connected
to a private site such as a Virtual Private Network (VPN).
In normal operation the MCM-4e provides you with a PATH to and from the Internet, which allows
your mobile platform to be connected without having wires attached to it. You operate the remote
client terminal exactly the same way you would if it were connected to any other Ethernet LAN. When
the MCM-4e is operating normally, it provides the path to and from the Internet and will be
transparent to you. Refer to figure 2-1 for an overview of the satellite connection.

Using Internet Data Services
To set up the PC computer for data service use, refer to section 4.
1. To use the Internet Data services for Internet browsing, email and file transfers, open your
Internet browser, email or other data program and proceed by operating that program as you
normally would to browse, email or efax. Please refer to the accompanying Software and User
Documentation for instructions on how to operate the ePipe and to turn the tunnel on.
Additional documentation on the ePipe can be found on the ML-IP.com web site
(http://ml-ip.com/).
When finished
Close your Internet browser, email or other data program.
Receiving Incoming Data Calls
The MCM-4e can receive incoming asynchronous data calls from a PSTN modem.
For simple connectivity (in either the ‘stand-alone’ mode or ‘VPN tunnel’ mode) the establishment of
the incoming asynchronous data call to the MCM-4e can be used to convey the application data
between the originating terminal within the customer’s private data network and the remote terminal
attached to the MCM-4e.
When used in conjunction with the VPN mode, the asynchronous data call to the MCM-4e can
be used to force the MCM-4e to initiate the VPN tunnel back to the customer’s private
TCP/IP data network. In this way, the full bandwidth of the VPN tunnel may be used to
transfer large data files more quickly. Once the VPN tunnel has been opened and the data
transfer commenced the PSTN data call can be released.

Provisioning the Single Antenna MCM-4e
Service provisioning
Each of the four SDMs requires a Globalstar subscription. Note: The Globalstar subscription for each
SDM includes the provision of a telephone number that also allows each SDM to receive incoming
asynchronous data calls.
Roaming Outside of the ‘Home’ Service Area
Prior to delivery, the MCM-4e will have been configured to operate within the Globalstar service area
designated to be you’re the ‘home’ service area.
In addition to being able to operate anywhere within the designated ‘home’ service area, the MCM-4e is
capable of operating within any Globalstar service area with which your Globalstar service provides
roaming capabilities.
Although the MCM-4e has the inherent capability of operating within any Globalstar gateway, it may
require some minor user configuration changes if it is subsequently required to operate within another
Globalstar service area. Some Globalstar gateways support both ‘packet data’ calls and ‘asynchronous
data’ calls while other Globalstar service areas support only ‘asynchronous data’ calls. The MCM-4e
was designed to operate in ‘Packet Data’ mode. The MCM-4e can operate in a Globalstar service area
that only supports the ‘asynchronous data’ mode, but at a lower data rate
Notes: For current details of Globalstar’s ‘packet data’ and ‘asynchronous data’ service areas,
refer to Globalstar’s web site at http://www.globalstar.com/pages/coverage.html
A call is disconnected when the subscriber leaves the service area of the Globalstar gateway controlling
the call. Although ‘in-call hand-overs’ between neighboring service areas are not supported on the
Globalstar system, the MCM-4e has the ability to maintain any VPN tunnels having more than one
Internet connection as the MCM-4e enters the neighboring service area. SDMs will disconnect and be
automatically reconnected by the MCM-4e to the Globalstar gateway controlling the neighboring
service area at different times. Thus, the VPN tunnel is likely to remain established (albeit with reduced
bandwidth through the transition period as each satellite modem connection is re-connected via the
Globalstar gateway serving the new service area).
Because certain Globalstar gateways have implemented Network Address Port Translation (1-N
NAPT) while others have implemented 1-1 Network address translation, the user of the MCM-4e
should ensure that the VPN tunnel does not use the IP(in IP) transport but instead uses TCP transport
within Globalstar areas where Network address port translation (1-N NAPT) is performed.

Planning Where to Position the Components
Determine where to position the components, how the cables will be routed and that the furnished
cable lengths will be adequate.
Site Selection
Choosing the best mounting location on smaller platforms, where there are fewer possible locations
to choose from, is frequently a compromise. The “best“ location for the antenna is the one that has
no blockage and is not in close proximity to other electronics or antennas that may interfere with the
MCM-4e or that the MCM-4e will interfere with.
Sometimes there are situations that you just can’t get around. In that case, do the best you can. At
moderate latitudes (between latitude 22 degrees and 52 degrees) there will always be two satellites
visible at any location. If an object blocking the antenna’s view of the sky is small (that is, blocks
only a small part of the sky), it should not cause an outage.
Single Piece Antenna
Determine the optimum mounting location, on top of the platform for the Antenna. Certain types
of antennae used with Global Positioning Satellite (GPS) receivers do not have the appropriate
band-pass filter (14.75MHz – 16.75MHz) fitted before the pre-amplifier stage. Use of this type of
antennae may cause a GPS receiver to be susceptible to interference from the MCM-4e. Where it is
found that a GPS receiver is experiencing interference from the MCM-4e, the distance between the
GPS antenna and the MCM-4e should be increased (by relocating one or both). If no suitable
alternative location can be found for either the GPS antenna or the MCM-4e, the GPS antenna
should be replaced with one that includes the appropriate band-pass filter. The MCM-4e should be
installed where:
•The antenna has a clear line-of-sight view to as much of the sky above the antenna as is
practical, down to an elevation of 10 degrees above the horizon. Choose a location where
masts or other structures do not block the satellite signal from the antenna as the platform
turns.
•The antenna is at least 5 feet away from other transmitting antennas (HF, VHF, GPS and
radar) that may generate signals which interfere with the Antenna, or that the Antenna may
interfere with. Although radio and radar interference is not common, the further away the
Antenna is from these other antennas, the less impact their operation could have on it.
•The Antenna assembly should be rigidly mounted to the platform. If necessary, reinforce the
mounting area to assure that it does not flex due to platform motion or vibration
