Test Modes, Local Loopback | Patton electronic 1186 specs

Functions of LEDs are as follows:

Fiber The green Fiber LED indicates reliable data on the fiber side

E1 The green E1 LED indicates reliable data on the G.703/G.704 side

LOS The red LOS indicates that syncronization between modems has not been established. Blinking red LOS LED indicates the presense of coding errors

NS The red NS LED indicates that the signal on the fiber side is too weak to be detected, which can be due to any of the fol- lowing reasons:

-break in the fiber optic cable

-length of the fiber optic cable exceeds the maximum dis- tance

-problem with Fiber LED.

ER Flashing red ER LED indicates errors in 511 test pattern

TM The yellow TM LED indicates that modem is in a test mode (Local/Remote Loopback or 511/511E test pattern). Opaque TM indicates normal operation.

5.3 TEST MODES

The following section describes the test patterns and loopbacks used in the Model 1186. The Model 1186 offers V.54 compliant local/remote loopback tests, plus a built-in V.52 BER test pattern gener- ator to evaluate the condition of the modems and the communication link. These tests can be activated physically from the front panel.

5.3.1 Local Loopback

The local loopback test checks the operation of the local Model 1186, and is performed separately on each unit. The following section describes how to perform a local loopback test between the Network and a local connection.

Any data sent to the local Model 1186 in this test mode will be echoed (returned) back to the user (see Figure 11). If two Model 1186 units are linked when the LAL is activated, data sent from the remote modem will also be looped back to the remote terminal equipment.

To test the local connection, follow these steps:

1.Activate LAL by moving the front panel toggle switch UP to "Local". Once the Local Loopback is activated, the Model 1186 transmit output will be connected to its own receiver. The TM LED will light up.

2.Perform a BER (Bit Error Rate) test on each unit using a separate BER tester. If the BER test equipment indicates no faults, but the data indicates a fault, follow the manufacturer's checkout procedures for the data terminal. Also, check the interface cable between the terminal and the Model 1186. The BER test can also be performed using a built-in 511/511E pattern generator. (See section 5.3.3 on how to use the built-in 511/511E pattern generator.)

3.Upon completion of the LAL test, return the front panel switch to the NORMAL position. The TM LED should turn off.
