WCDMA Call Processing

In order to successfully complete a GSM call process-
ing procedure, a test USIM card needs to be available.
Test USIM cards have default call parameters that al-
low users to perform call processing tests through GSM
base station simulators. This allows service technicians
perform simulations without accessing the customer's
cellular account.

Hardware Requirements

Refer to , "Hardware requirements," under, "GSM/
DCS/PCS Call Processing." Also Refer to Figure 13.

Software Requirements

None.

Call Origination (WCDMA)

Use the following procedures for call processing. The
screen shots are from a Rohde and Schwarz CMU 200
with WCDMA signalling options installed. The proce-
dures can be adopted to any other test box that will be
used to perform call processing.
1. Install the test USIM in phone.
2. Connect hardware as illustrated in figure 4.
Note: Control interface doesn't need to be con-
nected at this time.
