Wideband Digital Cross Connects
A SONET cross connect accepts various optical carries rates accesses the STS signals and switches at this level . it is idally used at a SONET hub as shown in one major difference between a cross connect and an add drop multiplexer is that broadband cross connect can be used for grooming of STS is or for broadband traffic management. For example it may be used to segregate high bandwidth from low bandwidth traffic and send it separately to high bandwidth switch and a low bandwidth switch. It is the synchronous equivalent of aDS-3 digital cross connect and support hubbed networks.
