Using the CALL DATA Screen
To View The Reverse Channel Words From a Mobile Station Origination
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 the
Active
field. The
Active
annunciator will light when the control channel
is turned on.
7. Dial the desired phone number on the mobile station and press the SEND key on the
mobile station’s handset. The mobile station signals the Test Set on the reverse control
channel with an origination message which includes the dialed phone number, the
mobile station’s MIN number and the mobile station’s ESN. If the mobile station
transmitted 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
Test Set will then reconfigure itself to the voice channel assignments set up in the
Voice Channel Assignment
section of the CALL CONTROL screen. The
Access
annunciator will then light while the Test Set signals the mobile station on the
assigned voice channel. The
Connect
annunciator will light if the mobile station
properly signals the Test Set on the reverse voice channel. The mobile station is now
connected to the Test Set on the assigned voice channel.
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.
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.
Step 7. and Step 8. in the above procedure can be reversed, that is, the desired
word can be selected first, then a mobile station origination can performed. If the
origination 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 origination 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).
