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.
