? Programmable two-wire signal headroom for 2.2 V rms metering
? High and low battery with automatic switching
? Only +5 V feed in addition to battery
? Selectable transmit gain (0.5x or 0.25x)
? 70 mW on-hook power dissipation in active state
? On-hook transmission
? Long loop battery feed tracks Vbat for maximum line voltage
? No power-up sequence
? 43V open loop voltage @ -48V battery feed
? Constant loop voltage for line leakage 10 k? @ -48V)
? Full longitudinal current capability during on-hook state
? Analog over temperature protection permits transmission while the protection circuit is active
? Line voltage measurement
? Polarity reversal
? Ground key detector
? Tip open state with ring ground detector
