1.
Highlight a desired timeslot number with the cursor.
2.

Protective resistors
The Protective resistor field provides the control for built-in protective resistors (470Ohms). These resistors are
used only in “Monitor” and “Transit-Monitor” operational modes.
If the field is set to “Off” value protective resistors are shunted.
Test pattern
This menu allows the user to set test pattern parameters and provides control for the test pattern sending. The
“Test pattern” screen is shown at the Figure
5.4
below.
Send pattern
The Send field allows to start/stop the insertion of current test pattern into timeslots selected in the “Line
interface/Test speed” menu.
