5.2.2 Displaying Line/Loop Status

To check the current status of the Model 2500RC Series and the associated circuit, go to the Main Menu and select item 4, “Display Line/Loop Status”1,2 . This will take you to a screen similar to the Line/Loop Status Monitor Screen (below).

NOTE1: To refresh the display with the most up-to-date information, key “4” and press [RETURN].

NOTE2: The error count is reset after each time it is displayed.

5.3 LOOPBACK TEST MODES

The Model 2500RC Series offers three loopback tests to evaluate the condition of the CSU/DSUs and the communication link: local analog loopback, remote digital loopback and telco loopback (C.O. Loopback).

5.3.1 Local Analog Loopback (LAL)

The Local Analog Loopback (LAL) test checks the operation of the local Model 2500RC Series. Any data sent to the local Model 2500RC Series in this test mode will be echoed (returned) back to the user device. For example, characters typed on the keyboard of a terminal will appear on the terminal screen (see Figure 11, below).

LAL Test Activation

The LAL test may be activated in one of three ways:

1.Toggle the front panel “Local/Normal/Remote” switch to the right hand side to the “Local” position.

2.Activate the LL lead from the DTE (Note: in order to use this option, the DTE Loop Control option must be enabled–see Section 3.2.4). If you are not sure which pin is the LL lead, please refer to the pinout diagrams in Appendix D.

3From a terminal, first go to the Main Menu and select item 3 to display the Software Switch Menu (Section 3.2.4) In the Software Switch Menu, select item “e” to go to the Local Line Loop Menu (see below). To activate LAL, select item 1.

LAL Test Procedure

Once LAL is activated, the Model 2500RC Series transmit output is connected to its own receiver. The “Test” LED should be lit. Follow these steps to complete the test:

1.Verify that the data terminal equipment is operating properly and can be used for a test. If a fault is indicated, call a technician or replace the unit.

2.Perform a BER (bit error rate) test on each unit using a separate BER tester (The Model 2500RC Series has a built-in BER tester–see Section 5.4). 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 2500RC Series.
