Locating Rear Panel Input Signal Connectors
One feature of the W-CDMA uplink format is the ease in which you can locate a rear panel input connector
for a particular signal application. This feature applies to both the DPCH and the PRACH. This procedure
guides you through the softkey menus to where you can view the information.

The
PhyCH Type
softkey opens another menu where you can select either the PRACH or DPCH mode.
The factory default is DPCH. You need to select the mode for which the input signal is intended. If the
input signal is the AICH for the PRACH, you would need to be in the PRACH mode to see which
connector accepts the AICH signal.
3. Select the channel mode,
DPCH
or
PRACH
.
Once a mode is selected, you will be returned to the previous softkey menu.
4. Press

Rear Panel
Ports
column accepts a baseband generator (BBG) chip clock signal. Figure 16-65 shows the position
of this information on the DPCH signal input display.
