6-14-8 EDACS TRUNKING MANUAL TEST-RADIO SIMULATOR
Entering the Repeater Simulator causes the COM-120C to perform an FM-Zero
operation to adjust the Receiver’s DC offset to zero. The screen displays the message:
“Doing FMZ...please wait.”
While in the Radio Simulator the Control Channel is continually monitored looking for
SITE-ID from the controller. If not found, the NC status is shown. When a SITE-ID
message is found, the status goes to IDLE.
This allows Group Calls to be made (Push-to-Talk) or calls to be made to the COM-120C
from another Radio as dictated by the Repeater. There are 3 main call-processing
sequences supported in the Radio Simulator. Perform a Group Call, receive a call in
response to a Channel Assignment message from a Repeater and receive a call in
response to a Channel Update message from a Repeater (if coming on-line during a
call).
Several error conditions can occur during the Radio Simulation. Error messages display
briefly under these conditions.
LOST CHANNEL
The Radio has lost
contact with the
Repeater during a
Group Call.
CHAN OUT OF RANGE
A channel assignment
from the Repeater was
out of pre-programmed
Channel range.
INVALID ID
An ID other than what
was set in the
Logical/Group ID fields
was used to call the Radio Simulator.
NO UN-MUTE FOUND
The Repeater has transmitted the channel assignment to the Radio
Simulator for calling the simulator, but did not send the Un-mute message
on the Working Channel.
NO CHAN ASSGN FOUND
The Channel Assignment message was not received from the Repeater
when a Group Call (PTT) was executed from the Radio Simulator.
