GSM fax and Data connection
EasyGate with fax converter has ability to send and receive GSM fax messages using
analogue fax Group 3 connected to telephone line FXS. The fax communication service
must be registered with your GSM operator. It is possible to establish data connection
using analog modem connected to FXS line. It is useful for devices with build-in
modem, without possibility to use serial line. The data communication service
must also be registered with your GSM operator.
Sending a fax message to GSM and modem connection
through GSM
When connected device is able to send CNG tone (1100Hz for fax 1300Hz for modem),
the gateway recognizes whether the call is fax or data, the connection will be
established automatically. When the tone is not send or some problems with
recognition occurred, is necessary to dial before destination number code *01* for fax
call or *02* for data call. This code us used to inform the Gateway, that the call is a
fax or data call.
Receiving a fax message from GSM
It is recommended to activate separate fax number on your SIM card –
multinumbering scheme. Fax messages must be routed to fax number, data call to
data number. Incoming fax, data and voice calls will be than automatically recognized.
It is possible to set ring pattern for fax and data call, different from the pattern for
voice call.
If the fax or data number is not activated, the call from analogue network routed to
your GSM number is not detected as fax or data call and is routed via the analogue
channel of GSM network and the connection is not successful. In this case it is possible
to set the gateway using DTMF commands using device connected to FXS line. These
commands can be used for data and fax routing to FXS line or serial line.
DTMF codes for fax receive:
n *9900# Reset of all following settings for fax receive
n *9901# The next call is fax, this setting is suspended after
receiving call or by command *9900#
n *9902# Fax routed to FXS, inactivate *9900# or device reset +
