7-3 PHONE INTERCONNECT TESTING
Configure the analyzer for trunk mode (paragraph
6-5) and Radio Initiated Testing (paragraph 6-6).
7-3.1 Radio Initiated Phone Interconnect
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: PHONE INTERCONNECT
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.
The trunking analyzer generates an idle
background pattern on the control channel and
prompts the operator to key the transmitter.
The operator keys the transmitter of the radio
by sending a phone interconnect request. The
request is received by the analyzer and the
data is displayed. The radio is then directed to
a voice channel where the appropriate Trunk I
or Trunk I EP II signaling is accomplished.
7. The status thermometer displays the major
signaling events that occur during a radio
initiated phone interconnect test. Refer to table
7-9 (Trunk I), table 7-10 (Trunk I EP II), table
7-11 (Trunk II auto affiliation disabled) or
table 7-12 (Trunk II with auto affiliation).
The trunking analyzer continues to transmit
data to keep the radio on the voice channel.
When the radio is on the voice channel, the
operator can test the DTMF capability of the
radio by selecting the
DTMF DECODE
softkey
from the "Meter:" cursor position. The DTMF
decode screen is used to display DTMF tones
from the radio.
While the radio is being held on the voice
channel, the operator has the option to select
other display screens by moving the cursor to
"Meter:" and selecting the desired metering
function. For example, the operator can switch
the analyzer to the RF Display screen and
rekey the radio to measure frequency error,
RF transmitter power, and frequency
deviation.
