● WAN 1 / 2
Parameter assignment as classic WAN interface:
The parameters of the WAN interfaces correspond to those of the TIM modules of the
type TIM 3/TIM 4. You will find a description in the Section
"WAN Access" tab (Page 41).
● WAN 1
Parameter assignment of the serial interface as virtual Ethernet interface for simple
Internet communication via GPRS.
An Ethernet TIM that you want to connect as an MSC station (or node station) to a GPRS
network via the GSM MD720-3 modem is connected to an Ethernet network via its serial
interface.
With a TIM 4R-IE, only WAN 1 supports the function of a virtual Ethernet interface. When
networking interfaces in NetPro, remember that the left interface of 2 interfaces of the
same type is not necessarily interface 1.
Follow the steps below to configure the interface:
– Select the serial interface (WAN 1 with a TIM 4R-IE).
– From the drop-down list in the lower part of the dialog, select the network type
"Ethernet" and assign it to the WAN interface by clicking the "New" button.
The drop-down list entry "Ethernet" is grayed out.
– Open the properties dialog of the network node by clicking the "Properties" button,
then connect the WAN network nodes with an Ethernet network and configure the IP
parameters. Close the dialog with "OK".
Back in the "Interfaces" tab, the MD720-3 is automatically assigned as "Modem type"
and the "GPRS connection mode" is enabled. The WAN interface now has parameter
settings for a virtual Ethernet interface.
– As the "GPRS connection mode", select either "MSC station" or "MSC node station".
The remaining MSC configuration is done in the SINAUT configuration tool. You will
find an overview of MSC configuration in the section
GPRS / Internet communication:
Overview of configuration (Page
15).
● Ethernet 1 / 2
The parameters of the Ethernet interface are displayed below the list.
In the list box for the (static) Ethernet interface, "Ethernet 1" (or "Ethernet 2") is selected
as default. You set the IP parameters of the Ethernet interface by clicking the
Properties... button, see Setting parameters for Ethernet nodes (Page 62).
Note
The two Ethernet ports of a TIM 4R-IE are not designed as a switch, but are intended for
connection to different networks. Operation in the same Ethernet network is not
permitted.
If this is ignored, it will not be possible to generate SDBs for the TIM. This is detected
during the verification in SINAUT node management and signaled.
The IP addresses of the two interfaces must therefore differ in at least one of the three
leftmost decimal (separated by a period) numbers (applies to the usual subnet mask
255.255.255.0).
When an Ethernet interface is selected, you have the option of setting the following
parameters:
