Loopback Status Summary Screen

Item selection 4, Loopback Control, from the Main Menu displays the loopback status information for all of the HTU-C, HRE, and HTU-R units monitored by the HFAC. Loopback Status (On, Off, or Not available) is presented for loopbacks to both the network and the customer at both the HTU-C, HRE, and HTU-R. Figure 16 illustrates the Loopback Status Summary Screen.

Loopback Options

By pressing a slot number followed by an S from the

Loopback Status Summary Screen, you will be presented with a slot-specific Loopback Options Screen (Figure 17). Multiple loopbacks can be initiated for each circuit. This screen graphically depicts the loopback activated by showing through reverse video, the path of the loopback and the locations it loops to. Also, the status indication changes from inactive to active. The initiation of a loopback is accomplished by pressing the corresponding number of the loopback desired, followed by an L.
