Communications between the GISS and GIS is across DKIST’s IEEE 802.3 Ethernet control network (see Figure 1). The connection is 100Base-FX running full-duplex over multi-mode fiber. The GISS connection to the network is through the use of a multi-mode fiber pair (TX, RX) using an SC-type connection to the local network switch. The GISS is rack-mounted in the computer room located in the S&O building, coudé Coude level.
The GIC is the distributed portion of the GIS responsible for the communication of GIS to the GISS. The GIC is located on the Utility level. The GIS interface to the GISS control network is a Stratix 5900 Service Router. The Services Router handles network security to segment the GIS from the rest of the enterprise network.
