You should test the DL3800E unit before you use it. If it, or an associated
module, does not operate properly during or after testing, call Quick Eagle
Networks Technical Support at: (408) 745-4200.
This chapter contains procedures for testing the DL3800E unit followed by
suggestions for troubleshooting problems.
You use the DTE AND NETWORK TESTS MENU to initiate and terminate
one DTE test and three network tests. The four tests are:
• DTE/NETWORK Loopback
• Payload Loopback
• LINE Loopback
• LOCAL Loopback
To initiate a loopback test in the DTE AND NETWORK TESTS MENU,
select TESTS from the INVERSE MULTIPLEXER MAIN MENU, and press
Enter
to open the menu.
Select a test on a specific network port, set to ON, select CONFIRM, and
press Enter.
To terminate or cancel the test, select it, set to OFF, select CONFIRM, and
press Enter.
The example in Figure 6-1 shows the TEST MENU.
NOTE: You do not need to inform the telephone company that you’re
running the tests. However, if the tests reveal a problem with a carrier’s
service or with the DL3800E, you should inform the carrier that the DTE
equipment or the DL3800E unit must be removed from service.
