3500988-0001 Revision A
Application Note – Phone/Fax
1.
The Hughes 9211 RJ14 port allows the connection of both a telephone and a fax or modem at
the same time (BGAN circuit switched network restrictions mandate that only one is in use at
any given time).
2.
The Hughes 9211 supports two distinct phone numbers, one for the voice line and the other for
the fax or modem line. Incoming phone calls will only ring the line associated with that phone
number.
3.
Automatic outgoing and incoming BGAN bearer selection means that no special configuration
or switching between voice and fax/modem is needed by the user (4kbps voice for phone,
3.1KHz clear channel for fax/modem).
4.
A two line splitter is required for this application –
see next page for sample splitters. However,
the customer can readily create their own splitter
wiring using commonly available telephony
hardware. The 9211 port is wired per the standard
RJ14 wiring convention (FCC 47 CFR Part 68 § 68.502).
5.
No splitter is needed for voice only operation.
Note: if you have a device that supports voice and 3.1kHz/fax with a single line, you can configure the
RJ14 port to support both services on line 1. Refer to the Telephony section.
