, or Leased/dial line.  Also, items such 

as bit rate,  protocol, and call type take effect only at the begin-
ning of a new call. 

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 ISU 2x64 automatically updates the Current Status menu to 
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.
