FAX and Data function 4.2

DTMF codes for data receive:
 *9800# Reset of all following settings for data receive
 *9801# The next call are data, this setting is suspended after
receiving call or by command *9800#
 *9802# Data routed to FXS, inactivate *9800# or device reset +
 *9803# Data routed to COM, inactivate *9800# or device reset +
Commands marked + are used to set parameters, which can be set permanently in
configuration program (PCManager). Using DTMF commands has higher priority, than
setting in configuration program, but is valid only till reset of gateway or inactivating
command.
Setting for the next call is only alternative solution, which is not able to substitute
using of multinumberig scheme (e.g. when unexpected voice call is incoming before
the fax or data call, this solution disables to receive it).
Supported fax and data protocols
Supported fax protocols
The gateway supports connection of analogue Fax Group 3 using protocols V.29, V.27
and V.27ter. Maximal data rate is 9,6kbps. The maximal data rate is strongly
dependent on line quality, which is tested on the beginning of connection, to avoid
data errors. The fax service is available up to field strength -90dBm.
Supported data protocols
The gateway supports connection of analogue modem using protocols V.34, V.32bis,
V.32, V.22bis, V.22, Bell 212A and Bell 103. Maximal data rate is 56kbps. For
connection between two modems is the data rate limited by the CSD data rate in GSM
network, the maximum is 14,4kbps.
Higher data speed could be useful only for GPRS connection. The maximal data rate is
strongly dependent on line quality, which is tested on the beginning of connection, to
avoid data errors. The data rate for GPRS connection is limited by actual speed of
GPRS transfer in GSM network too. This speed is often affected by network load.
