QUAD T1
Counter Menu
The T1 Port Counter Menu displays a total count of errors since
the last reset or since the QUAD T1 module was powered up. It is
useful in evaluating the performance of a T1 circuit over a
prolonged period of time.
It can also be used during testing—reset the counters and then
periodically press E
NTER at the menu prompt to refresh the display
and see if errors are accumulating.
To access the T1 Port Counter Menu, type "C" at the T1 Port
Performance Menu.
Figure 4-5 illustrates the T1 Port Counter
Menu, and Table 4-4 lists the menu items.
