Chapter 2, Product Description
The DCCH Call Processing Screens
Product Description
DIGITAL
MEASUREMENT
Screen
This screen enables measurements on a DTC (Digital Traffic Channel) by using
the Mobile Station Test Interface, as specified in TIA/EIA Interim Standard
IS-137. It also supports the TIA/EIA-627 Test Interface. Refer to the field
descriptions in
Chapter 7, “Screen and Field Descriptions,” on page 205 for more
information.
The difference between the measurements displayed on this screen and those
displayed on the CALL CONTROL screen is the connect state of the Test Set and
mobile. The CALL CONTROL screen requires that the Test Set be in the Connect
state (that is, maintaining a call with a mobile). The DIGITAL MEASUREMENT
screen does not require the Connect state. It does, however, require that the mobile
be in a special test mode as described in the standards mentioned earlier.
The test mode is enabled via the test interface. Each manufacturer which supports
this test interface provides a connector as per the specification. The individual
manufacturer should provide instructions for putting the mobile in the test mode.
