In a switch structure for circuit switching, part of the space switch functionality of a time-space (TS) switch core is broken out and arranged in groups of switch adapter boards, and the TS-switch core itself is divided into a matrix of smaller and independent TS-modules that are associated with the switch adapter boards. Each group of switch adapter boards is co-operating with a predetermined row of TS-modules in the matrix for input of data to the TS-modules in that row, and with a predetermined column of TS-modules in the matrix for output of data from the TS-modules of that column. In this way, it is possible to implement the switch structure into a number of subracks with a reasonable number of interconnections between different subracks, thus obtaining a truly modular TS-switch structure. |
