Using the CALL DATA Screen
To View the Decoded Reverse Channel Words from a Mobile Station Page
There are two methods that can be used to view the decoded RVCC words from a
mobile station page:
• View the decoded RVCC words from a page for a mobile station that has registered
with the Test Set
• View the decoded RVCC words from a page for a mobile station that has not registered
with the Test Set
Viewing the Decoded Reverse Channel Words from a Page to a Mobile Station that
has Registered with the Test Set
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, ensure that the Test Set is properly configured. 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. If the CALL DATA screen is not displayed, select CALL DATA under the To Screen
menu. The CALL DATA screen will be displayed.
6. Select the Active field. The Active annunciator will light when the control channel
is turned on.
7. Ensure that the mobile station has registered with the Test Set. See "Register a Mobile
Station" on page 144 for information on how to register the mobile station.
8. Select the Page field. The Page annunciator will light while the Test Set pages the
mobile on the forward control channel. If the mobile station responds properly on the
reverse control channel, the message RECC Return will flash momentarily in the
upper right-hand corner of the CALL CONTROL screen. The Access annunciator
will then light while the Test Set sends the mobile station an alert order on the assigned
voice channel. The mobile station should ring.
9. Press the SEND key on the mobile station. The Connect annunciator will light if the
mobile station properly signals the Test Set when the SEND key is pressed. The mobile
station is now connected to the Test Set on the assigned voice channel.
10. Select the Display Word field. A list of reverse channel words appears 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.
NOTE: 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.
See "CALL DATA Screen Message Field Descriptions" on page 170 for a
description of each of the available reverse channel words.
