41
Range - DHCP
IP address is assigned by GSM network according to
operator policy. It may be static or dynamic address.
Manual
IP address is assigned by GSM network to the value set in
Set IP field by user. This mode is applicable only when
operator policy allows forcing IP address by the user.
Default value - DHCP
Comments - Manual mode is allowed only in few GSM networks
8.2.3.6. Set IP
Function - enables manual entering of IP when parameter IP assignment is
set to Manual
Data type - IP number field
Range - 0.0.0.0 - 255.255.255.255
Default value - 0.0.0.0
Comments - forcing of IP address mode assigned by operator is serviced only
in few GSM networks
8.2.3.7. Virtual IP address
Function - defines IP address that will be placed in internal data header of
frames sent by the module.
Data type - IP number field
Range - 0.0.0.0 - 255.255.255.255
Default value - 0.0.0.0
Comments - Parameter mandatory in case of operating MT-101 module in
GSM networks where operator uses dynamic address translation
of internal addresses to static external addresses visible to
external users. The parameter enables placing the external IP
address under which the internal network node is visible in the
header for sent data frame. As a result, external recipients will
experience match of sender's IP with IP address written in data
header. It is necessary due to double authentication of received
data employed by MT-Data Provider (MT-DP).
8.2.3.8. Number of GPRS transmission retries
Function - defines number of retries of GPRS transmission in case of not
receiving confirmation in time defined by Transmission timeout
parameter
Data type - number
Range - 0....255
Setting this parameter to 0 results in sending data without
waiting for confirmation of error-free reception.
Default value - 3
Comments - In normal conditions, it is not recommended to set this value to
higher than 3. This effectively secures against loss of
transmitted data without hampering processing following rules.
Note that consecutive data will be sent after successful
conclusion of current transmission.
