Loopback Services
The R&S
CMW supports Service Options 2, 9, and 55. All service options meet the
requirements described in 3GPP2 C.S0013-A.
TX Measurements
TX measurements depend on the Reverse Radio Configuration (R-RC) of the MS. In
general O-QPSK measurements require a R-RC 1 or 2, whereas H-PSK measure-
ments require a R-RC 3 or 4.
Service Option 2 and 9
Service Option 2
and
Service Option 9
apply to systems with Protocol Revision
(P_REV) equal to 5 or lower. They provide a loopback of primary traffic information bits
through the MS using the Forward Fundamental Code Channel with Multiplex Option 1
and 2, respectively. The "FCH Frame Offset" is not editable and always set to
0
.
The FCH can be configured as follows:
●
Radio Configuration
The R&S
CMW sets the radio configuration to use for the Forward and Reverse
Fundamental Channel (F-FCH-RC and R-FCH-RC). The Multiplex Options (F-FCH-
MO and R-FCH-MO) are not selectable; they are set to 1 by the Service Option 2
selection and to 2 by the Service Option 9 selection.

Service Option 55
Service Option 55 applies to systems with Protocol Revision (P_REV) equal to 6 or
higher. The option provides a loopback of primary traffic information bits through the
MS; the Multiplex Option can be either 1 or 2.
The FCH can be configured as follows:
●
Sets the radio configuration to use for the Forward and Reverse Fundamental
Channel (F-FCH-RC and R-FCH-RC). The Multiplex Options (F-FCH-MO and R-
FCH-MO) are either 1 or 2 but equal for the forward and reverse channel. The
range of possible radio configurations depends on the multiplex option.
