Abstract: A packet forwarding unit such as a Digital Subscriber Line Access Multiplexer (DSLAM) receives Ethernet packets carrying real-time information and forwards the information therein on output lines such as Asymmetric Digital Subscriber Lines (ADSLs). The DSLAM includes a clock device having an extraction unit and an adaptive clock. The extraction unit analyzes received packets to select streams of received packets from one destination to one user, and the adaptive clock generates a reference clock signal according to the arrival times of packets in the selected streams. The clock signal is sent to time reference units in DSL modems for the output lines.

Abstract: A forwarding unit such as a DSLAM (8) receives (21) Ethernet packets and forwards information therein on digital subscriber lines (27). For forwarding voice information of received Ethernet packets a reference clock signal is generated by a clock device (28) and provided to modems (23) for the digital subscriber lines. The clock device includes an extraction unit (29) for selecting at least one stream of received Ethernet packets, and a clock signal generating unit, configured as an adaptive clock unit (31), for generating a reference clock signal according to arrival times of packet in selected packet stream or streams. The reference clock signal can be provided to time reference units (25) in the modems. The extraction unit can analyze received Ethernet packets to find streams of packets from one destination to one user, the packets of each of the streams carrying real time information belonging to a real time service and then select one or more streams to be used by the adaptive clock unit.

Abstract: An arrangement for painting all sides of an elongated rigid object comprises a closed container containing in its bottom portion a paint mixture of binder, monomer and pigment. The elongated object passes through the closed container above the surface of the paint mixture to be coated on all sides by the paint mixture, followed by passage through an apparatus for drying the bottom surface of the object. The object is freely suspended while passing through the closed container and the drying apparatus for the bottom surface, and then is passed to a drying apparatus for the top surface of the object.
