5.3 TEST MODES

The Model 1082 offers two proprietary loopback test modes, plus a built- in V.52 BER test pattern generator, to evaluate the condition of the modems and the communication link. These tests can be activated phys- ically from the front panel, or via the interface.

Local Line Loopback (LLB)

The Local Line Loopback (LLB) test checks the operation of the local Model 1082, and is performed separately on each unit. Any data sent to the local Model 1082 in this test mode will be echoed (returned) back to the user device (see Figure 13). For example, characters typed on the keyboard of a terminal will appear on the terminal screen.

To perform an LLB test, follow these steps:

1.Activate LLB. This may be done in one of three ways:

—Move the front panel toggle switch up to “Local”.

—Raise the LLB signal on the interface (see Appendix C, “Model 1082C and 1082D Interface Pin Assignments” on page 28).

Once LLB is activated, the Model 1082 transmitter output is con- nected to its own receiver. Data is also looped back to the line. The TM LED should be lit.

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 “Using the V.52 (BER) test pattern generator” on page 24. If the BER test equipment indicates no faults, but the data terminal indicates a fault, follow the manufacturer’s checkout procedures for the data terminal. Also, check the interface cable between the terminal and the Model 1082.
