Chapter 7. Test Menu
7-2 TSU 600 User Manual 61202076L1-1
Menu flow is normally depicted from left to right. Arrows on the lower
right of the screen indicate the scrolling direction to view additional
menu items. At every level of the menu, pressing Cancel returns the sys-
tem to the previous menu level. Pressing Cancel repeatedly returns the
system to the Main menu.
Network Tests
Network tests control the activation of loopbacks and the initiation of
data test patterns.
Network tests are run on the Network Interface (NI). You can select
three different test configurations to determine the type of loopback and
the pattern to run. Test results display in the LCD window.
Executing Network Tests will disrupt normal data flow unless only
TST DS0s are selected for testing.
Loopback Tests
A number of different loopbacks can be invoked locally from the front
panel, by T-Watch PRO commands, or remotely by using special in-
band codes (AT&T D4 network loop up and loop down codes). Addi-
tionally, the loopbacks can be remotely controlled by means of out-of-
band commands by the T1 ESF FDL or from T-Watch PRO by a modem
connection. See Figure 7-2.
