Using the CALL DATA Screen
To View the Decoded Reverse Channel Words from a Mobile Station Release
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. Select CALL DATA under the To Screen menu. The CALL DATA screen will be
displayed.
7. Select the Release field. The Test Set will signal the mobile station with a release
order. The mobile station will respond to the release order and cease transmission. The
Test Set will terminate transmission on the forward voice channel and the Connect
annunciator will turn off. The Test Set will then reconfigure itself for transmission on
the forward control channel, begin to transmit system parameter overhead messages
and the Active annunciator will light.
8. Select the Display Word field. A list of reverse channel words which can be
displayed will appear in a Choices: menu. Select the desired word from the list of
choices. 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 released. If the release 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 release does not have to happen while you are viewing the CALL DATA
screen. When the CALL DATA screen is viewed, the contents of the display
words will contain the decoded data from the last successful call processing
function (registration, origination, page, release, order).
