SYSTEM CONTROL CENTER - 2
Function. The SCC-2 is a computer-assisted, automated tool that helps SYSCON cells manage the network. It consists of a technical shelter, management shelter, and planning shelter (corps only). It is collocated within the SYSCON and provides the information for network management. See Figure 3-10.

Deployment. At corps, three SCC-2s deploy: two primary and one standby. The three are interchangeable. At division, there is one SCC-2 and it consists of the technical and management/planning shelters. The division SCC-2s are subordinate to the corps primary SCC-2, unless the division is in a stand-alone configuration.
Connectivity. The SCC-2 connects to an NC or LEN switch by CX-11230A/G cable. All network SCC-2s receive regular database updates from each other through a packet switch in the technical shelter. All traffic from the SCC-2 to the NCs, LENs, FESs, and RAUs is routed through the circuit switch.
Each SCC-2 has a technical shelter. The shelter has two computers: The transmission interface module (TIM) and the packet switch. One computer is usually used as the technical workstation, and the other is the packet switch controller. The TIM connects the SCC-2 to the other 16- channel trunk group from the NC switch.
The packet switch controller serves as the network management center. The switch controller is in the SCC-2. However, it does not control any circuit switch assets, or calculate radio links. It controls and monitors the packet switch network (PSN). It does not provide interaction with the circuit switch network.
The technical workstation acts as the focal point for the SCC-2. It controls the message traffic within, into, and out of the SCC-2. It assigns system management responsibilities to the other workstation and maintains the SCC-2 network database for all workstations. It also provides map data to the other workstations and passes along updates from the other SCC-2s in the network.
The SICPS tent is used to make up the SCC-2 operations center. This configuration may be set up differently to meet mission requirements. There are only two shelters used in the division SCC-2 configuration as opposed to the three which are shown in Figure 3-11.
