ABSTRACT:
The present invention concerns a method to perform central control of in-line element (Ei) in a tree-like network by a line terminator (LT). A plurality of network terminators (NT1, NT2, . . . , NTi, . . . , NTn) are coupled via one or more of such in-line elements (Ei) to the line terminator (LT) by dedicated branches and by a common branch, respectively. The method includes the steps of:determining by the line terminator (LT) a first plurality of bits (A) according to an identification of a selected element (SEL-E) and a second plurality of bits (B) according to an identification of a locally predefined function (SEL-F) whereby the selected element (SEL-E) has been selected by the central control out of the in-line elements (Ei) in order to execute its locally predefined function (SEL-F); andincluding by the line terminator (LT) in a grant message (G) the first plurality of bits (A) and the second plurality of bits (B);forwarding the grant message (G) by the line terminator (LT) to the in-line elements (Ei) in order to thereby impose execution of the locally predefined function (SEL-F) according to the second plurality of bits (B) upon the selected element (SEL-E) according to the first plurality of bits (A).
