5.4.7 Local Loopback at Both Ends
When this loopback is activated, it will cause all data transmission from the local user device to
be looped back toward the receive side of that same local device. At the same time, all data
transmissions from the remote unit will be looped back towards the receive side of the remote
device (as shown in Figure 40).
