2. Connect the control (console) port of the unit to a PC.
3. Connect the Ethernet port to the appropriate device where the upload package will be stored.
4. On a Window 2000 or WinXP machine, open a Command Prompt and run the script. (The script will
connect to the default 192.168.200.10 IP address). If using Win9x, a TFTP client will be needed.
5. The TFTP process takes about 90 seconds, the unit will reboot automatically when done.
Operating Local Analog Loopback (LAL)
The Local Line Loopback (LAL) applies to serial port data traffic, it does not affect traffic from the Ethernet
port. The local Loop test checks the operation of the local Model 3086, and is performed separately on each
unit. Any data sent to the local Model 3086 in this test mode will be echoed (returned) to the user device (i.e,
characters typed on the key-board of a terminal will appear on the terminal screen).
Figure 10. Local Line Loop
To perform a Local Analog Loopback test, follow these steps:
1. Move the front panel toggle switch UP to “Local.
2. Verify that the data terminal equipment is operating properly and can be used for a test.
3. Perform a V.52 BER (bit error rate) test as described in secton “BIT Error Rate (V.52) Diagnostics” If the
BER test equipment indicates no faults, but the data terminal indicates a fault, follow the manufacturer’s
checkout procedure for the data terminal. Also check the interface cable between the terminal and the
Model 3086.
Operating Remote Digital Loopback (RDL)
The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 3086s,
as well as the communication link between them. Any characters sent to the remote Model 3086 in the test
mode will be returned to the originating device (i.e, characters typed on the keyboard of the local terminal will
appear on the local terminal screen after having been passed to the remote Model 3086 and looped back). See
Figure 11.
