SX4e TDMA 800 • SX4e Tri-Mode 11 Technical Manual
Originating Fax and Data Calls
Sending a Fax Message
1) Set up your fax machine just as you
would for a wired telephone line.
2) If your fax machine has a 'prefix'
setting, set it to # * 2. If your pro-
gram does not have such a setting,
add # * 2 to the phone number as
shown in the example below:
Example: If you are sending to
1-800-123-4567, enter
#*218001234567. The '# * 2' tells
the SX4e to use the analog mode for
this call only.
3) Your fax should then proceed normally.
NOTE: If the network does not have
analog channels available, the call will
be unsuccessful. Try the call at a later
time.
Sending Data
1) Connect your computer modem to
the Phonecell SX4e exactly the
same way you would to wired tele-
phone service.
2) If your modem communications
program has a 'prefix' setting, set it
to # * 2. If your fax machine does
not have such a setting, add # * 2
to the phone number as shown in
the example below:
Example:If you are sending to 1-800-123-4567, enter #*218001234567. The '#
*
2' tells the
Phonecell to use the analog mode for this call only.
3) Your data transmission should then proceed normally.
NOTE: If the network does not have analog channels available, the call will be unsuccessful. Try the
call at a later time.
NOTE: As a result of using this dial string prefix, the SX4e will be placed in the analog mode and an
analog channel will be requested before the call is dialed. If the request is successful, the data rate
negotiations will commence and the call will continue. The "FWT Status" LED will indicate an analog
call by flashing green.
Receiving Fax and Data Calls
When your fax machine or modem answers a call, the Phonecell will decode the answer tone from
the local device. This will cause the Phonecell to go to analog mode, regardless of which mode is
currently set, to receive the data or fax. The "FWT Status" LED will indicate an analog call by flash-
ing green. You do not need to do anything to allow your unit to receive fax or data calls. However,
the facsimile machine and/or computer data modem must be connected to the Phonecell SX. (See:
Step by Step Fax Instructions). If the call is not completed successfully, the remote caller should
retry the call immediately The Phonecell SX4e will remain in analog mode for a short time after call
failure waiting for retry.
Refresh FWT to Digital Mode
When the analog fax/data call ends, the "FWT Status" LED will return to continuous green indicating
the FWT has returned to its normal operating digital mode.
