To View the Decoded Reverse Channel Words from a Mobile Station Registration
1. If not already done, condition the Test Set. See "Conditioning the Test Set for Call
Processing" on page 130 for further information.
2. If not already done, ensure that the Test Set is properly configured. See "Configure the
Test Set" on page 131 for further information.
3. Connect the mobile station to the Test Set as shown in Figure 14, "Connecting a Mo-
bile Station to the Test Set," on page 115.
4. Turn on the mobile station.
5. If the CALL DATA screen is not displayed, select CALL DATA from 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. Select the Register field. The Register annunciator will light while the registra-
tion is in process. 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 Active annunciator will light when the registra-
tion has successfully completed.
8. Select the Display Word field. A list of reverse channel words which can be dis-
played 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 dis-
played in the lower portion of the display.
9. If a word is chosen which was not part of the decoded reverse channel message stream,
all the fields will be blank when it is displayed.
10. See "CALL DATA Screen Message Field Descriptions" on page 144 for a descrip-
tion 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 registered. If the
registration 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 registration 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 be the
decoded data from the last successful call processing function (registration, origination,
page, release, order).
