2. Configuring Terminals
This section provides basic information on how to configure HSD-440 Mark 2 Terminals for
operation with user devices.
A. Setting up Airborne Networks
For information about setting up airborne networks that use Swift 64 and SBB services,
refer to the HSD Terminal Developer’s Guide, MN-1252-13005.
B. Mapping User Devices for ISDN Services
HSD-440 Mark 2 Terminals support connection to a multitude of user devices, allowing
the user to customize their system. The HSD Terminal Developer’s Guide,
MN-1252-13005, provides more information about ISDN devices and services.
C. IMNs
IMNs are unique routing numbers that act similarly to telephone numbers. IMNs are
assigned by Inmarsat to each service type (64 kbps Speech, 3.1 kHz Audio, 56 kbps
data, and 64 kbps data).
When registering your system, request IMNs for each service-type device attached to
the HSD-440 Mark 2 Terminal on the Service Activation form. Although the service
provider may support an unlimited number of IMNs assigned to a particular system, the
number of physical connections available on a system defines the number of IMNs
supported.
NOTE: To get assigned extra or multiple IMNs per service type, you must request them
from your service provider when filling out your service registration and
application form.
The HSD Terminal Developer’s Guide, MN-1252-13005, provides more information
about IMNs.
D. MSNs
MSNs act as identification and routing codes for user devices attached to the HSD-440
Mark 2 Terminal ISDN bus. MSNs identify the device on the system so that incoming
calls route to the appropriate device. Each device must be assigned an appropriate MSN
to identify to the Inmarsat system what type of service that device needs on outgoing
calls. The MSNs also provide routing information for incoming calls.
The HSD Terminal Developer’s Guide, MN-1252-13005, provides more information
about MSNs.
