Abstract: For control of a testing system, a test module control program module (TUC) arranged on a line trunk group (LTG) in a process-controlled telecommunications system (K) is connected to a unit under test (TA, TS, TL . . . ) via a testing unit (TU) subdivided into test modules (FTEM, LMEM, LVMM) and implements testing procedures. The line-oriented test module control program module (TUC) initiated by a central control program module (TLFI) controls the routines to be implemented at the testing system for seizing and releasing the testing unit (TU). The test module control program module (TUC) is entered into every device memory table (DPS) belonging to the testing unit (TU) and, when called in, respectively implements a specific test procedure. In the execution phase, the test module control program module (TUC) remains in a defined status. The test routines are implemented and monitored without active participation of the test module control program module (TUC).

Abstract: Testing method for subscriber line testing (TS, TL) in a program-controlled communications system or switching equipment (EWSD), whereby a first or a second test execution program module (CT, LT), a test address data program module (TA) and a test decision program module (UC) initiates and implements testing procedures. These are read out of a test data program module (CD) by version-associated query sequences in the sense of a decision tree (E) for the identification of test limit values. The test limit values that are needed for a line test can be prescribed by the operator.

Abstract: A process for providing film tubes with anti-blocking means in that the film tube is cooled internally by an aqueous suspension containing a suspended release agent directly after extrusion, the excess suspensions are sucked from the interior and the tube, which is additionally cooled on the exterior in a water bath, is freed of remaining liquid by squeezing rollers.
