    I-DSL64 USER’S MANUAL 4.2 Local Loopback When the local loopback is activated, it will utilize the local site of the I-DSL64 (see Figure 7). This will test the transmitting/receiving functions of the local site. During this test, the remote unit will lose DSL synchronization. When the local loopback test is released, the system will restart and return to its initial state.
