Verify that the terminating resistor jumpers are set to OFF, when
the set is in a point-to-point configuration and the terminating
resistor is in the closet or a 440A4 is connected on the line.
d
Verify that the terminating resistor jumpers are set to ON, when
the set is in a point-to-point configuration and the terminating
resistor is
not in the closet or a 440A4 is not connected to the
line.
d
Verify that the terminating resistor jumpers are set to OFF, when
the set is in a multipoint configuration and the terminating resistor
is either in the closet or a 440A4 is connected on the line, or the
jumper is set to ON in one of the other sets on the line. NOTE:
Only one terminating resistor is used for multipoint configuration.
