7-4.2 Radio Initiated Call Alert Test Sequence,
Trunk II Si
gnaling
Configure the analyzer for trunk mode (paragraph
6-5) and Radio Initiated Testing (paragraph 6-6).
NOTE
SMARTZONE configures the analyzer to
perform a SMARTZONE affiliation sequence
prior to executing the dispatch test sequence.
If the radio is not capable of SMARTZONE
auto affiliation, the selection should be set to
DISABLED.
1. Enter the following parameters:
Sig Type: Trunk II
ID Disp: HEX or DEC
Call Seq: CALL ALERT
2. Set the System ID to match the radio system
ID and one of the system IDs in the Radio
Configuration screen in order to decode radio
ID information.
NOTE
The system ID entered must match the system
ID of the radio. Otherwise the radio will not
lock onto the control channel. Refer to
paragraph 6-8, Radio Configuration.
3. Enter the CCTx or Control Channel number.
Enter the VCTx or voice channel number.
NOTE
Splinter channels can only be entered by
frequency. Standard channels can be entered
by frequency or channel number (channel
numbers only map to standard channel
frequencies).
4. Set the monitor attenuation and port selection.
Suggested port selection is RF I/O with 20 dB
attenuation.
5. Set the generator attenuation and port
selection. Suggested port selection is RF I/O
with -50 dB for the level setting.
6. Press the start test softkey.
NOTE
If SMARTZONE auto affiliation has been
selected, the operator is prompted to apply
power to the radio. Once the test radio is
turned on, it begins to search for a control
channel. When the radio finds the control
channel, it performs an auto registration
sequence with the analyzer, and the
registration data is displayed.
7. The status thermometer displays the major
signaling events that occur during a radio
initiated Call Alert test. Refer to table 7-18
(Trunk II auto affiliation disabled), or
table 7-19 (Trunk II with auto affiliation).
The trunking analyzer generates an idle
pattern on the control channel and prompts the
operator to key the transmitter. When the
radio sends an ISW, the analyzer decodes it
and displays it. If the ISW call type is a call
alert, the analyzer will wait a short period of
time and send an acknowledgment to the raido
that the call alert has been received, and the
test is termianted. During the execution of the
test sequence, the status thermometer is
appropriately updated.
8. Press the stop test softkey to terminate testing.
