formed.
Additional transitions
The transitions in the figure above are not complete. The "Off" state can be reached
from any state by turning off the cell signal (ON | OFF). Moreover, incidents like a time-
out or a loss of the radio link cause additional transitions.

Connection States for Reduced Signaling
The main connection states in reduced signaling mode are described in the following
table.

Description
Off
Off
No signal transmission / no connection to the UE
On
Off
The R&S
CMW provides a downlink signal containing the following physical
channels: P-CPICH, P-SCH, S-SCH, P-CCPCH and PICH.
The UE can synchronize to this downlink signal.
On
On
The physical channels relevant during a connection are provided by the
downlink signal. The configured RF input connector is active, so that the
uplink signal can be received.
It is possible to set up a test mode connection.
Please note that for HSPA test mode direction = HSPA (
on page 186) the enabled HSDPA and HSUPA downlink channels are only
present when the R&S
CMW has successfully completed synchronization to
the UL signal.
Control commands initiated by the R&S
CMW switch between the listed states. The fol-
lowing figure shows possible state transitions.
