A process for the control of forwarding packets of completed packet sequences of packet-switched networks as well as a software module, an interface, a terminal device, and a server for this purpose. In these packets of packet sequences, information is transported segmentally. First, that the authorization of a packet to be forwarded is tested by using the transported information of the packet by way of comparison with a certain criterion, at least whenever the packet belongs at the start of a packet sequence (C11A, C12A, C13A). Second, that successive packets of a packet sequence except the initial packet are required to be tested before being forwarded up until the transported information has been made completely available and is comparable with the criterion, and, last, that a packet of a packet sequence is forwarded if it could be determined when subjected to comparison that forwarding the packet is allowed or if it has already been determined by testing a previous packet of the same packet sequence that forwarding the packet of this packet sequence is allowed.

The invention relates to a method of operating an interface device (IWF) for connecting a first telecommunication subnetwork (ISDN) operated in synchronous time-division multiplex mode (ISDN) with a fixed assignment of time slots to transmission channels using a first signaling protocol (SI1), to a second telecommunication subnetwork (ATM) operated in a statistical multiplex mode (ATM) with a transmission capacity assigned to each connection by free agreement using a second signaling protocol (SA1), the interface device performing a conversion between the first signaling protocol and the second signaling protocol, wherein during each connection setup the signaling is converted in such a way that the number of transmission channels (Ch1, . . . Ch6; Ch20, . . . , Ch30) reserved in the first subnetwork (ISDN) for the connection to be set up and the transmission capacity assigned to said connection in the second subnetwork (ATM) are adapted to one another, as well as an interface device and an exchange with such an interface device.

An apparatus for automatically forming yarn reserve windings selectively on either end of an empty tube prior to winding a yarn package thereon utilizes a threaded spindle and spindle nut assembly for supporting one of a pair of tube clamping plates for selective longitudinal displacement of a tube clamped therebetween during rotation of the tube to place the yarn reserve windings thereon. The hand of the threaded connection between the spindle and spindle nut determines the longitudinal direction in which the tube is displaced and, in turn, determines the end of the tube about which reserve windings are to be formed. In one embodiment, the spindle and spindle nut assembly are exchangeable for a like assembly formed with opposite threads, thereby to alter the longitudinal direction of tube displacement. In another embodiment, an interiorly and exteriorly threaded bushing is interposed between the spindle and the spindle nut, to form oppositely mating threads between the bushing and the spindle and between the bushing and the nut. Set screws are provided to selectively fix the nut with respect to the bushing or, alternatively, to fix the spindle with respect to the bushing, thereby to change the longitudinal direction of tube displacement without necessitating an exchange of the spindle and nut assembly.
