Systems with CDS
In newer systems with CDS and one BPE FPGA on the CDDM
board, each CP can support the following:
Systems with IFSS-TC
In older systems with IFSS-TC, each CP can support the
following:
• 12 inroutes, 256/512 ksps Turbo BCH at 1/2, 2/3, and 4/5
forward error correction (FEC) rate
• 6 inroutes, 1024 ksps Turbo BCH at 1/2 and 4/5 FEC rate
• 3 inroutes, 2048 ksps Turbo BCH at 1/2, 2/3, and 4/5 FEC
rate
RCDs are housed in a cPCI chassis. The HX gateway rack can
support either one or two cPCI chassis, with three RCDs per
chassis. Each RCD can support a single inroute type
(combination of symbol rate, FEC rate, and coding type).
Network Management
Support Services
(NMSS) subsystem
The NMSS is the name given to the functional elements running
in the NMSS (network management and support services) server.
These elements are:
• Vision - provides configuration and control interface for
many of the NOC components
• Conditional Access Controller - provides access control for
information transmitted through the HughesNet service
• Management file server (MFS) - provides a repository for
software and configuration parameters to be downloaded to
NOC components
