Using the CALL DATA Screen
To View the Decoded Reverse Channel Words from an Order to Change the Transmit Power
Level of a Mobile Station
1. If not already done, condition the Test Set. See "Conditioning the Test Set for Call
Processing" on page 141 for further information.
2. If not already done, configure the Test Set. See "Configure the Test Set" on page 142
for further information.
3. Connect the mobile station to the Test Set as shown in Figure 17, "Connecting a
Mobile Station to the Test Set," on page 119.
4. Turn on the mobile station.
5. Ensure that the Test Set is in the Connect state. See "Page a Mobile Station" on
page 145 for information on how to bring a mobile station up on a voice channel.
6. If the CALL DATA screen is not displayed, select CALL DATA under the To Screen
menu. The CALL DATA screen will be displayed.
7. Select the Order field and select it. A Choices: menu is displayed showing the
various power levels which the mobile station can be set to. Select the desired power
level. The Access annunciator will light while the Test Set signals the mobile station
with an order to set its power level. If the mobile responds properly, the message REVC
Return will flash momentarily in the upper right-hand corner of the CALL
CONTROL screen. The Connect annunciator will light when signaling is complete.
8. Select the Display Word field. A list of reverse channel words which can be
displayed will be presented. Position the cursor on the desired word and select it. The
decoded contents for each of the fields in the selected word will be displayed in the
lower portion of the display.
9. If a word is chosen which was not part of the decoded reverse channel’s message
stream, all the fields will be blank when it is displayed.
10. See "CALL DATA Screen Message Field Descriptions" on page 170 for a
description of each of the available reverse channel words.
Step 7. and Step 8. in the above procedure can be reversed, that is, the desired
word can be selected first, then the mobile station can be sent an order to change
transmit power level. If the order is successful, the contents of each display word
contained in the reverse control channel’s message stream will be updated when
the decoding is complete.
The ordered to change transmit power does not have to happen while you are
viewing the CALL CONTROL screen. When the CALL DATA screen is viewed,
the contents of the display words will be the decoded data from the last successful
call processing function (registration, origination, page, release, order).
