RESOURCE SAVING DEVICE AND COUPLING OF A CONNECTION IN A TELECOMMUNICATION SYSTEM

摘要

The present invention relates to a coupling node (MG1) for coupling connections in a telecommunications system which includes networks (N1, N2) that have separate signal formats. The coupling node includes switch and trunk functions (CP21, CP23) corresponding to the signal formats and telecommunications functions, for instance encoder/decoder (F21) and echo canceller (F22), wherein the node can be coupled into a connection through the medium of a selector (PS1). The functions are carried by circuit boards (CB1-CB9) in magazines (SR1) and the circuit boards have signal processors (DSP11-DSP13) having access points (SAP11-SAP14). The functions have a hierarchically arranged address which denotes access points, processors, circuit boards and magazines. The internal communications resources (105, 160) of the coupling node (MG1) are used in a resource-saving manner by using the hierarchic address to interconnect two consecutive functions of said functions in a connection. On the basis of the address, the node is able to select speciments of the functions (CP21, CP23, F21, F22) that lie close together. Primarily, there are chosen the two functions that can be accessed via the same access point (SAP11), secondly the two functions that are found on the same signal processor (DSP11), thirdly those that lie on the same circuit board (CB1), and fourthly those that are found in the same magazine (SR1).
