State Definitions
(continued)
Secondary Control Mode States
(continued)
Current: Tip to Ring
—
VITR
I
A voltage proportional to the ac tip to ring differential
current, tip to ground current, or ring to ground cur-
rents, appears at TESTLEV output. Use this state for
ac measurements.
I
Choice is determined by primary control mode table.
I
Differential current is selected by choosing powerup
forward or reverse from the primary control mode
table.
I
Tip to ground or ring to ground current is selected by
first choosing powerup forward or reverse from the
primary mode table, then choosing tip amp or ring
amp from the primary mode table.
I
TESTSIG input is on.
I
Customer applies ac test tone or V
REF
to select an ac
or dc measurement.
Reference Voltage
I
A voltage proportional to the internal dc reference
voltage V
REF
appears at the TESTLEV output.
I
TESTSIG input is off.
I
This is the calibration state for voltage measure-
ments.
TEST Off
I
Device mode is per primary control mode table.
I
The TESTSIG input is deactivated.
I
TESTLEV output is high impedance.
I
Device mode is per primary control mode table.
Special States
Thermal Shutdown
I
Not controlled via truth table inputs.
I
This mode is caused by excessive heating of the
device, such as may be encountered in an extended
power cross situation.
I
Upon reaching the thermal shutdown temperature,
the device will enter an all-off mode.
I
Upon cooling, the device will re-enter the state it was
in prior to thermal shutdown.
I
Hysteresis is built in to prevent oscillation. In this
mode, supervision output NSTAT is forced low
(off-hook) regardless of loop status or if the discon-
nect logic state is selected.
Battery
Out of Range
I
Not controlled via truth table inputs.
I
This mode is caused by a battery out of range; that
is, the battery voltage rising above
or below a speci-
fied threshold.
I
Upon reaching the specified high or low battery volt-
age, the device will enter an all-off mode.
I
Upon the battery returning to the specified normal
operating range, the device will re-enter the state it
was in prior to the low battery shutdown.
I
Hysteresis is built in to prevent oscillation. In this
mode, supervision output NSTAT is forced low
(off-hook) regardless of loop status or if the discon-
nect logic state is selected.
