TRUNKING APPLICATIONS
7-1 BASIC TRUNKED RADIO TESTING
This section of the manual contains information on
typical test setups to perform some of the more
common trunked radio tests using the R2670
Digital Communications System Analyzer with
Trunking Option.
The start test softkey initiates the test sequence
defined by the parameters selected on the trunking
screen. If the parameters selected are not valid, the
test sequence is terminated and an error message is
displayed. If the parameters selected are valid when
the start test softkey is pressed, the start test softkey
is replaced with the stop test softkey. For a list of
error and warning messages, refer to Appendix E.
7-2 DISPATCH TESTING
Configure the analyzer for trunk mode (paragraph
6-5) and Radio Initiated Testing (paragraph 6-6).
7-2.1 Radio Initiated Dispatch Test
Sequence, Trunk I and Trunk I EP II
Signaling
1. Enter the following parameters:
Sig Type: Trunk I or Trunk I EP II
ID Disp: HEX or DEC
Call Seq: DISPATCH
NOTE
For test sequences with ID Disp set for DEC,
the six-digit Unit ID decoded from the ISW is
the personality ID of the radio and not the
unit ID. When ID Disp is set for HEX, the unit
ID is displayed in hexadecimal. The Fleet and
Subfleet IDs are always displayed in
hexadecimal independent of the ID Disp
selection.
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. 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.
7. The status thermometer displays the major
signaling events that occur during a radio
initiated Dispatch test. Refer to table 7-1
(Trunk I signaling) or table 7-2 (Trunk I EP II
signaling).
8. Press the stop test softkey to terminate the test
sequence.
