RNC Node

When you enable Direct Tunnel in a GGSN, MME, SGW Nodal test case, the RNC Node defines the Gn interface node for all SGSN nodes in the test.

In GGSN Nodal test case, when you select Test Activity as Command Mode and Direct Tunnel on the Test Configuration tab, enter the Number of RNCs/BSSs per SGSN.

Option: 1 - 1000.

Tcl Parameter: SgsnUsrNumRncsBss

In MME Nodal test case, Command Mode Test Activity supports multiple RNC nodes and also during handover, you may configure multiple Target RNC Control Nodes. The configured nodes are evenly distributed to each UE and will not change during the handover.

In SGW Nodal test case, RNC User Node terminate the Gn interface with the PGW Gn SUT when you select SGSN Node Emulation on the Test Configuration tab.

Ethernet Configuration

With an Ethernet User Node, you can define:

The IP address and routing options... The Starting IP will increment for each node.
The MAC Address to override the Hardware MAC address so the packets sent out of the interface will use the provisioned MAC address rather the Hardware MAC Address.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
Custom port selection... and error injection with the Advanced... button.
