"Manual"
Each state transition step must be initiated separately. You must trig-
ger three state transition steps to reach the state "MAC Activated"
from the state "SCC Off" (via "SCC On" and "RRC Added").
This mode is useful for debugging of the UE. From each state you
can go back to the previous state or continue to the next state. For
example from state "RRC Added" you can go to "MAC Activated" or
to "SCC On".
Remote command:
Enable Speech Codec
If this parameter is enabled, the LTE signaling application is connected to the speech
codec of the audio board when the cell is switched on.
Only one signaling application can be connected to the audio board at a time. The
parameter is only configurable while the cell is switched off.
Option R&S CMW-KS510 is required. The audio board and a speech codec must be
installed (R&S CMW-B400B and R&S CMW-B405A).

Remote command:
2.4.5 I/Q Settings
The parameters in this section configure the I/Q output paths and/or the I/Q input
paths. This is relevant for external fading scenarios and for the "I/Q out - RF in" sce-
nario. Only for these scenarios, the section is present.
Depending on the scenario, the section configures only one I/Q output path or one, two
or four pairs of input and output paths. Typically an R&S AMU200A is connected. For
carrier aggregation scenarios, you can configure different settings for PCC and SCC.
If you use the "I/Q out - RF in" scenario, specify the external delay of the test setup in
the setup dialog. This allows the "LTE Signaling" application to compensate a time
delay in the output path.
