Line Loopback

This test allows the loop interface (LINE) section of the local T3SU 300 to be tested from the remote T3SU 300 over the actual T3 circuit. Testing from the remote end of the circuit is performed by using a 511 test pattern or DTE data generated by the remote host. With this test, the T3SU 300 transceiver receives data from the network and loops it back toward the network through its transmitter. The transmitted data is identical to the receive data (including framing errors) and can therefore be accurately tested by the carrier for errors. See Figure 6-4.

The Line Loopback test is only available in loop timed mode

(CONFIGURATION ->DS3 NETWORK ->DS3 TIMING ->LOOP).
