7-4.4 System Initiated Call Alert Test
Sequence, Trunk II Signaling
Configure the analyzer for trunk mode (paragraph
6-5) and System Initiated Testing (paragraph 6-7).
NOTE
Fleet, Subfleet, and Unit ID information must
be entered before the execution of a System
Initiated test. If a Radio Initiated test is
executed prior to the System Initiated test,
these fields are automatically updated. If
required, refer to paragraph 6-8.1 for in-
formation related to entry and storage of sys-
tem/fleet map configurations.
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.
3. Target Unit, Calling Unit
If a radio initiated dispatch, phone
interconnect, or call alert test has been
executed prior to the system initiated test, the
Target Unit ID and Calling Unit ID decoded
from the ISW will be displayed. If the operator
wants to change the Target Unit ID or Calling
Unit ID, simply move the cursor to the
appropriate position and enter the new number.
In the system initiated test sequence, the target
Unit ID contains the data for the test radio
while the Calling Unit ID contains the data for
the "other radio" that is trying to call alert the
target unit.
4. 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).
5. Set the monitor attenuation and port selection.
Suggested port selection is RF I/O with 20 dB
attenuation.
6. Set the generator attenuation and port selection.
Suggested port selection is RF I/O with -50 dB
for the level setting.
7. Press the start test softkey.
The trunking analyzer generates an idle pattern
on the control channel. After a short period of
time the analyzer sends a call alert message to
the radio. When the radio receives the call
alert, it issues an acknowledgment to the
analyzer and an audible call alert tone is
generated by the radio. The analyzer terminates
the test sequence and displays the test ended
message when the acknowledgment is
received.
8. The status thermometer displays the major
signaling events that occur during a system
initiated Call Alert test. Refer to table 7-21
(Trunk II auto affiliation disabled), or
table 7-22 (Trunk II with auto affiliation).
