Dialing From Tel1 Or Tel2; Connecting The Isdn Device - Inmarsat GX-9 Operating Manual

BGAN provides circuit switched fax service via an ISDN 3.1KHz audio channel. You may connect your
analog fax machine to either an ISDN terminal adaptor which is connected to the GX-9 ISDN port or
directly to the TEL1 (RJ-11) port. Even though it is more convenient to connect an analog fax to a RJ-11
port be aware that the BGAN fax calls are charged at ISDN rate (usually higher than the BGAN low rate
voice service).
A voice call made via TEL1 will be charged as an ISDN 3.1kHz audio service – if user did not
used the forced service dialing sequence (see below).
