Embodiment Construction
[0049] The present invention will be described in detail below by taking VC-4 space-division cross-connect as an example and in conjunction with the accompanying drawings.
[0050] figure 1 It is a block diagram of the self-routing system of synchronous digital cross-connect in the present invention, including: a service board 101 and a cross-connect chip 102, wherein the service board 101 includes a transmission terminal function module 1011 and a self-routing sending module 1012, and the cross-connect chip 102 includes a self-routing receiving module 1021 and a cross-connect matrix module 1022 , the self-routing receiving module 1021 includes a self-routing extracting module 10211 and a cross-connect control memory 10212 .
[0051] After the service board 101 completes the processing of the transmission terminal function module 1011, when the system control needs to configure the self-routing mode, the self-routing sending module 1012 sets the starting address of the self-rout...
