The FELCOM 50 terminal receives incoming calls via the IMN phone numbers.
IMN numbers are assigned to the following ports by the user:
•
ISDN port
•
RS-232 serial data port
•
RS-422 serial data port
•
USB serial data port
Calls are made as ordinary international (Satellite) calls by dialing the
international prefix (normally 00) followed by
870
and the IMN number, e.g.:
00
870
762420510.
The common Ocean Region access no.
870
connects the call to the dialed
FELCOM 50 regardless of the Ocean Region the user currently communicates
through.
If the Net service provider does not support access no.
870
, call the Ocean
Region directly:
871 - AOR-E

872 - POR
(Pacific
Ocean
Region)

Call announcement from fixed to mobile:
The LES uses the MES’s Forward Identity (FWID) to communicate with the MES,
and the Terminal Identity (TermlD) to identify the IMN number and the service in
use.
The FWID together with the TermlD replaces the need of the IMN number to be
transmitted through the Inmarsat system in order to identify the MES and the
specific equipment attached to it. This means that LES routes an IMN number
received from the fixed net to the specific FWID and TermlD identifying the MES.
The MES identifies the FWID and the TermID and routes it to a Multiple
Subscriber Number (MSN) which is programmed in the attached equipment.
FURUNO provides a table to identify which TermlD is routed to an MSN.
