Connecting the Hardware Components
The figure below shows a typical physical connection for interworking between legacy 3GPP networks and
LTE.

Component
Function
Agilent PXT
(E6621A)
LTE system simulator.
8960 (Lab
Application)
Legacy 3GPP network simulator.
For UTRAN simulation, a lab application of E6703
I
(E6785
I
) or later is required.
For GERAN simulation, a lab application of E6701J (E6785
I
) or later is required.
Ethernet (LAN)
Connection
Enables the exchange of signaling messages or packet data.
NOTE: There are multiple LAN Ports on the rear panel of the 8960 test set. For LTE
interworking, LAN 2 PORT is required to exchange signaling messages or packet data.
(LAN 1 PORT is optional, but it is still useful for other LAN operations such as protocol
logging, firmware downloads or screen captures.)
RF Interface
The UE must be able to communicate with both simulators. To accomplish this, it is
common to use an RF splitter to connect the mobile to both test sets simultaneously.
