7.0 TEST MODES The following section describes the test patterns and loopbacks used in the Model 1194. The Model 1194 offers local/remote loopback tests, plus a built-in V.52 BER test pattern generator to evaluate the condition of the modems and the network (T1/E1 lines) and fiber links. These tests can be activated physically from the front panel. Before initiating a loopback test, the user needs to select Local or Remote loops via DIP switch S2-1 located on the underside of the

To test the local connection, do the following: 1. Set S2-1 to the OFF position. 2. Locate the port label (P1-P4) above or below the front panel switches, Activate local loopback for a network port by moving the appropriate front panel toggle switch UP or DOWN. A yellow TM LED corresponding to the port under test will turn on. 3. A BER (Bit Error Rate) test can be performed using a BER tester at the far end of the T1/E1 link.
