The Local Line Loopback (LLB) test checks the operation of the local Model 2112, and is performed separately on each unit. Any data sent to the local Model 2112 in this test mode will be echoed (returned) back to the user device. - Page 14 If the test is working properly, the local modem's red “ER” LED will glow. A successful “511/E” test will confirm that the link is in place, and that the Model 2112’s built-in “511” generator and detector are working properly.
