Abstract: In the telecommunication network, telecommunication connections are directed from telecommunication terminal equipment on the transmission side (A) via an origin node (ON), via transit nodes (TN1, . . . TN7) to telecommunication terminal equipment on the reception side (B). An origin node number, the A call number, the destination node identity number and also the B call number are inserted into signalling information of the connection to be set up. In the nodes involved in the setup of the connection it is checked whether the A call number is to be modified. In some cases, the A call number may be supplemented and in other cases it may be supplemented and abbreviated.

Abstract: Telecommunication connections in a telecommunication network are directed from a telecommunication instrument (A) on the transmission side via an original node (ON) and transit nodes (TN1, . . . , TN7) to a telecommunication instrument (B) on the reception side. A number denoting the original node (ON), the A call number, the identity number of the target node and the B call number are inserted in signaling information for the telecommunication connection to be made. A test is performed in the nodes concerned in the connection on whether the A call number should be supplemented by the identity number of the node concerned. Such an addition to the A call number is done only in the original node. Thus the A call number can be simply assessed in the telecommunication instrument (B) on the reception side.

Abstract: In a meshed network, telecommunication calls from a transmitting-end telecommunication terminal (A) are routed via an originating node (ON), via transit nodes (TN1, . . . , TN7) and a destination node (DN) to a receiving-end telecommunication terminal (B). To prevent network loops, the node which is immediately next on the route is determined in transit nodes on the basis of the originating node number and on the basis of the destination node identification number. The node numbers of all the nodes passed through can be inserted into the signaling information assigned to the telecommunication call, the following node on the route also being determined on the basis of the node numbers.

Abstract: An overhead support for carrying medical appliances and providing supply lines in the medical field comprises support arms and a support column. In order to allow a simple and cheap manufacture of such an overhead support, the support arms are made of an extruded profile having a substantially rectangular cross section, side walls, a top wall, a bottom wall, longitudinal webs extending between the top wall and the bottom wall in a direction substantially parallel to the side walls in spaced relation thereto, and a channel for the supply lines, the channel being defined by the top and bottom walls and the webs.

Abstract: In a line connector system an incorrect interconnection of different lines shall be excluded. This is achieved by connecting a female connector (1-3, 1-6) to one line and a male plug (2-3, 2-6) to the other line, the female connector and male plug having a defined total length when connected; the total length may for example exactly correspond to the distance between two holding members (4, 5) of a holder (3) which receives the connected coupling members with the lines connected thereto. The individual female connectors and male plugs, respectively, have a respective different length such that the total length of incorrect coupling members in a connected state deviate from the predetermined length, whereby for example an insertion of the connected coupling members into the holder is impossible.
