Pushbutton Loopback
Front panel LBK SEL pushbutton (SW1) controls loopback mode as described here:
To initiate a network loopback, press SW1 once and hold for 5 seconds. The NTWK LBK LED flashes rapidly,
I
indicating the network loopback is "arming." After 5 seconds, the network loopback enables, the NTWK LBK LED
turns On solid, and SW1 can be released.
To initiate a customer loopback, press SW1 twice and hold for 5 seconds. The CUST LBK LED flashes rapidly,
I
indicating the customer loopback is "arming." After 5 seconds, the customer loopback enables, the CUST LBK LED
turns On solid, and SW1 can be released.
To initiate a dual (bidirectional) loopback, press SW1 three times and hold for 5 seconds. During this time, the
I
NTWK LBK and CUST LBK LEDs flash rapidly, indicating the dual loopback is "arming". After 5 seconds, the dual
loopback enables, the NTWK LBK and CUST LBK LEDs turn On solid, and SW1 can be released.
If SW1 is released before the arming period expires, the loopback does not initiate, preventing an inadvertent
loopback.
I If a loopback is in effect, pressing SW1 disables the loopback, regardless of initiation point.
Time Out
After a loopback or pattern test is initiated, unless terminated manually, a time out returns the loop to normal
operation after a selected time of 20 min, 60 min, 120 min, or 24 hrs. The timer is reset at any point by sending the
FEAC loop up code. The test time out can be set or disabled through the craft interface. Pressing the LBK SEL
button during a test releases the loopback and returns the unit to normal operation.
CONTROL PORT OPERATION
The NIU3 PM front panel DB-9 provides an RS-232 interface for connection to a controlling terminal. To initiate a
terminal session, insert a DB-9 jack into the RS-232. The terminal interface operates at data rates from 1.2 kbps to 19.2
kbps. The asynchronous data format is fixed at 8 data bits, no parity, and 1 stop bit. The supported terminal type is
VT100 or compatible.
NOTE: When conducting a terminal session, always select VT100 mode in the Settings menu prior to making the craft
connection.
Terminal Session
The NIU3 PM synchronizes upon insertion in a powered-up shelf or housing. After synchronization, terminal sessions
provide access to screen menus for provisioning, monitoring, testing, or obtaining performance or event history.
Terminal screens are password protected with "ADTRAN" as the password. The adjacent menu tree identifies the
menu screens (not all are depicted).
NOTE: If using a personal computer with terminal emulation capability, disable all power saving programs.
Otherwise, communication between the PC and the NIU3 PM may be disrupted, resulting in misplaced
characters or screen time outs.
