 back an allocation to the calling set. The access network reacts on this allocation and makes a direct connection between the calling set and the access server. Thereafter the connection between the user and the data network is established without going through the local exchange and the V5.2 interface on bearer channels (B-channels) even though the local exchange still monitors the call through the C-channel for signalling. Thus, the public telephone network will not be loaded by the long time data traffic.
The invention add functionality already existing in the V5.2 interface standard to set-up internal connection in the access network to dedicated networks for data communication with for instance an internet. The invention will not interfere with the ordinary telephone traffic to subscribers outside the actual access network and/or data traffic of other kind than the one in the data network to which the access server(s) are directly connected to. The invention can act together with the AXE-system. The present invention relates generally to vacuum filtration devices, and more particularly to a novel disposable manual vacuum filtration device for separating solid particulate from a liquid specimen and which finds particular application where a relatively modest degree of vacuum and evacuated volume are required for filtration.
It is a common practice in the testing and analysis of many types of solid materials to place a sample of the material into a liquid reagent after which the liquid reagent is filtered from the solid reactant leaving it available for diagnosis or further testing or washing with other reagents. Similarly, liquids such as various types of body fluids may have solid test reactants admixed therewith after which the solid reactants are extracted from the liquid by filtering to facilitate analysis of the reactants. Still further, liquids which in their natural state may have micro-organisms present are frequently analyzed by filtering the micro-organisms from a liquid sample for incubating and analysis.
One technique for filtering solid reactants or microorganisms from liquid reagents or carriers is to employ a vacuum filtration device having a filter element on which a liquid sample is placed in a manner enabling the liquid to be drawn through the filter by vacuum so that the solid constituents are retained on the filter element. See, for example, U.S. Pat. Nos. 2,005,406, 2,896,787, and 3,782,175 each of which employs a vacuum chamber adapted to support a filter element at its upper end and which is operative to filter a liquid sample through the filter element when the vacuum chamber is connected to a source of vacuum.

Thereafter the association between the user and the data net is prove without going through the local substitution and the V5.2 interface on bearer channels (bel - channels) even though the local substitution still monitors the cry through the C - channel for signalling. therefore, the public telephone network will not be loaded by the retentive time datum traffic. 
 The invention total functionality already existing in the V5.2 interface standard to set - up inner connection in the access network to dedicated networks for data communication with for instance an internet.

The invention can act together with the AXE - arrangement. The present invention relates generally to vacuum filtration devices, and more peculiarly to a novel disposable manual void filtration device for separating solid particulate from a liquid specimen and which line up particular application where a relatively modest degree of vacuum and evacuated volume are required for filtration. 
 It is a common practice in the testing and analysis of many character of hearty materials to place a sample of the material into a liquid reagent after which the fluid reagent is filtered from the solid reactant leaving it available for diagnosis or further examination or washing with early reagents. Similarly, liquids such as various types of body fluid may have solid trial reactants admix therewith after which the solid reactants are extracted from the liquid by filtering to help analysis of the reactants. Still far, liquids which in their lifelike state may have micro - organisms present are frequently analyze by filtering the micro - organisms from a liquid sample for incubating and analysis. 
 One proficiency for filtering solid reactant or microorganisms from liquid reagents or carrier is to employ a vacuum filtration device having a filter element on which a liquid sample is placed in a manner enabling the liquid to be drawn through the filter by vacuum so that the hearty part are retain on the filter element.
