11.3.3 Loopback Screen

The Loopback (Figure 11-5) facilitates loopback detection by allowing the user to
enable/disable automatic time out and also get the loopback status of the channel. This feature
will provide the digital loopback (both audio and signaling) when activated by a 2713 Hz tone
level and duration. When a validated tone is detected the channel disconnects the user and
provides loopback of signals received from the network. This loopback is performed at "equal
level" without inserting any gain or loss in the path. In addition a "make busy" signal is be
applied toward the user. Table 11-8 shows the Loopback screen of actions.
