SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
3. Type the appropriate terminal category number appropriate Multi-Channel
Configuration (
11, 12, or 13), and then press Enter.
A system message appears stating that the EEPROM has been updated.
This completes the configuration of the terminal category. You now need to
configure the LES Access Codes.
D. Configuring LES Access Codes (All Modes)
This section describes how to configure the LES access codes provided by your Inmarsat
service provider in HSD and HSD-X transceivers.
Note: You can remove the label that covers the LES Access Codes LEDs once you have
configured the LES Access Codes.
(1) General Overview
Inmarsat Service Providers (ISPs) operate Land Earth Stations (LES). The ISPs are
typically public telephone companies of the country where the LES is located.
Using satellite communications antennae and up-and-downlink communications
equipment, the LES converts the space segment to a format compatible with public
and private telephone and data networks. Each satellite is associated with a number
of LES that fall within its coverage.
Inmarsat assigns each LES an access code. These access codes are used by the
Inmarsat system to route calls to the correct Ocean Region Satellite and LES.
New and upgraded HSD units, with Control Processor software version 5.7 or later,
are shipped with the factory default LES Access Codes set to ‘0’ (zero). All HSD units
(including HSD-X units in Multi-Channel configurations) must be configured with the
valid LES Access Codes provided by your Inmarsat Service Provider.
(a) Changing Default LES using the HSD Maintenance Port Utility Program
The LES access codes can be configured using the HSD Maintenance Port Utility
Program accessed by connecting a computer running a VT100 terminal
emulation program to the RS-232 Maintenance Port on the HSD (or HSD-X)
transceivers (refer to
"Test and Fault Isolation" on page 4-1 for connection
settings and cabling information).
The LES access codes for HSD-X transceivers can either be configured directly,
through the HSD-X RS-232 Maintenance Port, or by “passing through” the
HSD-128 by activating the console mode feature. (To activate console mode, in
menu 18, press X).
When configuring the LES access codes using the HSD Maintenance Port Utility,
the application requests the input of a Secondary LES Access Code. At the time
of writing, the Inmarsat LES have not implemented the recognition of the
