Function
Negative battery supply voltage used for ringing or on-hook
(–25 V
Analog ground:
TIP and RING refer to AGND
Output of voltage divider defining DC line potentials; an external
capacitance allows supply voltage filtering (output resistance 60 k )
Differential two-wire AC input voltage; at TIP/RING outputs multiplied by
–6 and related to
Differential two-wire DC input voltage; at TIP/RING outputs multiplied by
–30 (ACTH and ACTL mode) or –60 (ACTR mode) and related to
Binary logic input, controlling the operation mode. Must be connected to
– IO2A/B of SLICOFI
voltages for voice transmission and internal ringing are used.
– GND, when three supply voltages for voice transmission and external
ringing are used.
Ternary logic input, controlling the operation mode
Ternary logic input, controlling the operation mode; in case of thermal
overload (chip temperature exceeding 165 °C), this pin sinks a current
of typically 150 A.
Current output: longitudinal line current scaled down by a factor of 100.
Current output: transversal line current scaled down by a factor of 50.
