Abstract: The present disclosure relates, according to some embodiments, to telomere resolvases (e.g., TelA variants) having a turnover number over 1.

Abstract: A subscriber line apparatus including linefeed driver circuitry for providing a DC feed for a tip line and a ring line of the subscriber line from a power supply in accordance with linefeed driver control signals. Bypass circuitry couples the tip and ring lines to the power supply in accordance with a power mode control. The tip and ring lines are coupled to the power supply through the linefeed driver circuitry in a first power mode. The linefeed driver circuitry is bypassed to couple the tip and ring lines to the power supply in a second power mode.

Abstract: An apparatus for offloading power includes a power offload element providing a supply drop from a first supply level to a second supply level. The supply drop varies in response to a control signal. A signal processor of a subscriber line interface circuit provides the control signal. A linefeed driver of the subscriber line interface circuit is coupled to receive the second supply level for driving a subscriber line.
