Pass Deny
Response To PSU

If a Local PSU (affiliated through the
VR) PTTs and the System sends back a
Deny response, the VR does one of the
following:
* if the Pass Deny Response Box is
checked → the VR sends a Deny
message to the PSU and the call is
cancelled.
* if the Pass Deny Response Box is
unchecked → the VR enables the PSU
call to be repeated locally (to the other
Local PSUs) but not to the System.
