CROSS-CONNECTION ARCHITECTURE FOR SDH-SIGNALS COMPRISING TIME- AND SPACE DIVISION SWITCH GROUPS

摘要

An SDH cross connect architecture is realized by switching the signals as bits in the space switch. The bit signals between the space switch and the time switches are multiplexed. In this way it is possible to linearly expand the capacity of the space switch to a much larger size before its quadratic expansion begins. The invention is applicable for the cross-connection of SDH signals on i.a. STM-1... STM-16 levels.
