8Connect between System ComponentsThe WJ-MPU955A Operating Instructions describes the connection between the WJ-MPU955A CPU with systemcontrollers, a CPU switch unit, digital video encoder devices, digital video decoder devices, and layer 3 networkswitch units. If you are not familiar with the above, we recommend that you read “Connect with System Devices”section of the WJ-MPU955A Operating Instructions first.This section will focus on new devices and connections that only associate with the WJ-ASC960 system. Global Data Network and System DomainsThe global data network is an IP-based network that connects two or more system domains together. The network isalso called system data control network. The system domains use this network to pass system control and operationcommands, as well as system data information, between domains.Global Data Network Diagram Global Network and System DomainsAs stated on page 6, the WJ-ASC960 system only has one GX switch node. The digital video network is an IP-basednetwork, which is created to transmit digital video streams within a system domain or cross multiple system domains.It is part of the GX switch node, which consists of all the GX encoder and encoder devices. When designing a newsystem, we recommend that you separate the global data network and digital video network.Digital Video Network DiagramDomain #1Domain #2Domain #3Domain #4Global DataNetworkDigital VideoNetworkDomain #1Encoder #1Encoder #2Encoder #4Decoder #1Domain #2Domain #3Encoder #3Decoder #2WJ-GXE900WJ-GXE900WJ-GXE900WJ-GXE900WJ-GXD900WJ-GXD900OPERATESTATUSMPEG2 Encoder WJ-GXE9001 2 3 4 5 6 7 8OPERATESTATUSMPEG2 Encoder WJ-GXE9001 2 3 4 5 6 7 8OPERATESTATUSMPEG2 Encoder WJ-GXE9001 2 3 4 5 6 7 8OPERATESTATUSMPEG2 Encoder WJ-GXE9001 2 3 4 5 6 7 8OPERATE1ACT1000100LINK1 STATUS 2 3 4 5 6 7 8MPEG3 Encoder WJ-GXD900OPERATE1ACT1000100LINK1 STATUS 2 3 4 5 6 7 8MPEG3 Encoder WJ-GXD900
