A METHOD AND A CROSS-CONNECTION ARCHITECTURE FOR ERROR-FREE CHANGE-OVER OF A CROSS-CONNECTION MATRIX |
摘要 |
A change-over command for the cross-connection matrix controlling the cross-connection of digital transmission lines (AU4#1...#16) must be distributed to all modules (T, S) of the cross-connect so synchronized that the error-free operation of the cross-connect can be maintained also during the change-over of the matrix. According to the invention this is made in two steps, whereby a preparatory signal ('special') is transmitted to all synchronization circuits (AU/TU), and then a byte (CM) indicating the change-over command is transmitted from the synchronization circuits (AU/TU) through the cross-connect in the frame administrative block carried in the signal flow (AU-4). |
