... V for Le9500B, or –100V for Le9500C and Le9500D. For Le9500D during ringing only this voltage may be extended to –145 V. The supply has to be externally adjustable. It has to be adjusted back to no more than -100 V for other operation states. Further, when –145 V is used for ringing special care should be applied to prevent certain faults from happening such as tip to ring, tip or ring to ground ...
