Automatic battery switch selects V
off-hook conditions.
All supervision circuits except for ring trip detector
are active.
Overhead is set via pin OVH.
TESTLEV output is in the high-impedance mode,
and TESTSIG input is off unless this feature is

PPMOUT is in the high-impedance mode, and
PPMIN input is off unless this feature is selected via
the secondary control table.
NSTAT represents the loop closure detector status.
Scan clamp circuitry is active.
Loop closure is active.
All ac transmission, dc feed, and other supervision
circuits, including ring trip, are shut down.
PPM is powered down.
Thermal shutdown is active.
Battery window comparator sense shutdown is on.
On-hook transmission is disabled.
Pin PT is positive with respect to PR, and V
applied to tip/ring.
Switch break switches (SW1 and SW2) are closed,
and ring access switches (SW3 and SW4) are open.
When the scan clamp circuitry is on, overhead volt-
age is fixed and not controlled by OVH. Also the cur-
rent limit is not the normal current limit set at V
NSTAT represents the loop closure detector status.
Tip amplifier is on, tip break switch is open.
The device presents a high impedance (>100 k ) to
pin PT and a current-limited battery (V
Common-mode current detector is on.
Ring trip detector is off.
Output TRGDET indicates current flowing in the ring
lead.
This is not a defined state in the primary control
mode table. It is achieved via the powerup and the
ring amp states in the primary control mode table.
