Front Panel DTE Indicators
The front panel DTE indicators (see Figure 4-1) reflect the status
of each DTE port on the ISU 2x64. The indicators show the cur-
rent state of the port being displayed from the Current Status
menu. To change the DTE indicators between the two DTE ports,
use the Up and Down arrow keys to bounce between the two
DTE ports Current Status menus. Once this menu is exited, the
DTE indicators reflect the status of the DTE# that was last shown.
See Table 1-A on page 3 for a listing of the front panel DTE indica-
tors.

the DTE# that is receiving an incoming call For example, if the
Current Status
menu shows the state of DTE#1, and a call is
incoming on DTE#2, the ISU 2x64 automatically changes the dis-
play to show the Current Status menu for DTE#2. Change this by
using the Up and Down arrow keys to select either DTE.
