The cross-connect matrix is the core of the system. It
implements the add/drop of the services and the mixed
transmission of multiple services. It can do cross-connect with
four granularity levels: VC3, VC4, VC4-4C and VC12. An open
universal high-speed serial bus is used as the backplane bus for
the interconnection of cross-connect matrixes and line cards. It
supports mixed access of the Ethernet, ATM, and TDM.

Software Principle

The software system of THE ZXA10 S300 consists of three layers:
Transmission NMS SMN software (including the man-machine
interface and NMS server), NE order wire control board software
and line card software (including TAA board, TDM, ATM and EOS
line card).
From the view of NM, the software structure of the ZXA10 S300
is shown in Figure 7.
