7-3.3 System Initiated Phone Interconnect
Test Sequence, Trunk I and
Trunk I EP 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.
1. Enter the following parameters:
Sig Type: Trunk I or Trunk I EP II
ID Disp: HEX or DEC
Call Seq: PHONE INTERCONNECT
2. Set the System ID to match the radio system ID
and one of the system IDs in the Radio
Configuration screen.
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 Fleet, Subfleet, and Unit ID.
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 OSW
pattern for the radio to lock to. After a short
period of time, the analyzer will send a
message to the radio instructing it to ring. The
radio sends a message to the analyzer when the
call has been answered. At that time, the
analyzer directs the radio to a voice channel
and provides the appropriate Trunk I or Trunk I
EP II handshake.
8. The status thermometer displays the major
signaling events that occur during a system
initiated phone interconnect test. Refer to
table 7-13 (Trunk I signaling) or table 7-14
(Trunk I EP II signaling).
Once on the voice channel, the operator can
modulate the carrier with tones, or voice, and
select other displays.
9. To complete the last step on the status
thermometer and end the test sequence, the
operator must return to the System Init
selection. From the "Meter:" cursor position,
the operator completes the test sequence by
pressing the
hangup softkey.
The trunking analyzer prompts the user to hang
up the phone. When the analyzer detects that
the phone has been hung up, the status
thermometer is updated, the ISW decode field
is updated, and the test ended message is
displayed on the screen.
