Push-Button (Ack); Craft Interface (C.i.) Jack - GE JungleMUX SONET Technical Practice

Note: Any of the above alert conditions is latched for 500 ms except for the
Intrusion alarm which is latched for 20 sec. If during this time no new alert
condition has been observed, the LED stops flashing.

Push-button (ACK)

The first use of the push-button is a LED and microprocessor test. If the ETHER-
1000 unit is operating normally, holding the front panel pushbutton down causes
all the LEDs to light. The main use for this test is to verify 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 ETHER-1000 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 disable the unit‟s Line ports 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 shelf without 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. VistaNET is a Microsoft Windows based software that allows the
user to configure the unit and monitor its status through the CI port.
The Craft Interface can also be used for loading a new firmware to the unit. This
can be carried out using GE-supplied software tool. During the firmware upgrade
process the unit configuration information is retained.
