Test Modes, Local Line Loopback LLB | Patton electronic 1092ARC

ER	glows red to indicate the likelihood of a Bit Error
	in the received signal. During the 511 or 511/E
	test, ER flashes to indicate that the Test Pattern
	Detector has detected a bit error.
TM	glows yellow to indicate that the Model 1092ARC
	has been placed in Test Mode. The unit can be
	placed in test mode by the local user or by the
	remote user.
NS	(No Signal) glows red to indicate that the local
	Model 1092ARC has not yet connected with the
	remote Model 1092ARC.

5.2 TEST MODES

The Model 1092ARC 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 physically from the front panel, or via the interface.

5.2.1 Local Line Loopback (LLB)

The Local Line Loopback (LLB) test checks the operation of the local Model 1092ARC, and is performed separately on each unit. Any data sent to the local Model 1092ARC in this test mode will be echoed (returned) back to the user device (see Figure 12, below). 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 to the right to “Local”.

-Raise the LLB signal on the interface (see Appendix B).

-Set Local Loop from the VT100 screen.

Once LLB is activated, the Model 1092ARC transmitter output is connected 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 Section 5.2.3. 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 1092ARC.

5.2.2Remote Digital Loopback (RDL)

The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 1092ARCs, and the communication link between them. Any characters sent to the remote Model 1092ARC in this test mode will be returned back to the originating device (see Figure 13, below). For example, characters typed on the keyboard of the local terminal will appear on the local terminal screen after having been passed to the remote Model 1092ARC and looped back.

Important! Do not send a 511 test pattern from the test equipment when you connect external test equipment to the 1092ARC .
