Push-button (ACK)
The first use of the push-button is a LED and microprocessor test. If the 2W
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 connection is established to the unit’s CI port. On establishing this
connection, the software will automatically clear the unit’s Channel settings (will
set them to “–“) and restart the unit at which point the user can configure the unit
to the desired settings. If the unit is inserted with the ACK button pressed and
then removed and inserted normally (no local VistaNET connected), all previous
settings will remain.
Note
: Inserting the unit into the equipment shelf without the ACK button pressed
may cause a traffic disruption in an in-service system.
Craft Interface (C.I.) Jack
The Craft Interface allows a user to connect a PC computer serial (COM) port to
the unit. The CI is an RJ-11 connector, which transmits and receives a 9600 b/s
RS-232 signal. A Microsoft-Windows-based VistaNET software allows the user
to configure the unit and monitor its status through the CI port.
