Push-button (ACK)

The first use of the push-button is a LED and microprocessor test.
FXS unit is operating normally, holding the front panel pushbutton down causes
all the LEDs to light. The main use for this test is to determine that the front
panel LEDs are functional and that the microprocessor firmware code is running
normally (microprocessor is not locked up).
Note: The microprocessor test does not cause any disruption in traffic.
The second use of the push-button is to put the unit into a "sleep state". This
state is enabled when the 2W FXS unit is inserted in the shelf with the ACK
button pressed. In this condition, the micro ignores all settings until a local
VistaNET or JCI connection is established to the unit's CI port. On establishing
this connection, the software will automatically clear the unit's Channel setting
