Abstract: A device for deblocking lenses attached to a block has at least one securing device supporting a lens and having an opening for a block suspended from the lens. At least one holding-down device is provided for pressing the lens supported on the securing device against the securing device. At least one impacting device with a striking member movable from below against the securing device for striking the securing device is provided. The securing device and the holding-down device are supported to be movable against a spring-elastic restoring force in a striking direction of the striking member.

Abstract: A network termination (NT) with a network interface (U.sub.KO), several subscriber interfaces (S.sub.O 1, S.sub.O 2), a control unit (CPU) and an internal bus (IBUS) is indicated for a telecommunications network. Information is transmitted on the network side in a frame structure by the time division multiplex method. The frame structure contains several useful information channels and one or more signaling channels. The control unit (CPU) assigns the useful information channels to the terminals in such a way, that each terminal has at least one channel available for the transmission of useful information. In addition, the network terminations (NT) of several subscribers are combined in the circuit of a network termination arrangement (NTE) outside of the subscribers' premises, and is jointly supplied by a voltage transformer (ACDC). A power supply that is independent of the telecommunications network supplies the voltage transformer (ACDC).
