TELEMETRIX 500 SPACE BRIDGE (T500SB)
OVERVIEW
 The RT Logic Telemetrix® 500 Space Bridge (T500SB) provides a seamless bi-directional OSI Layer 2 Bridge or Layer 3 Routing interface between a terrestrial Ethernet (IEEE 802.3ab, 1000BASE-T) network and an Ethernet network on a space vehicle.

 
 For the Layer 2 forward link, the T500SB accepts Ethernet packets into Gigabit Ethernet Interfaces, performs CCSDS Encapsulation, and generates AOS Frames for transmission to the space vehicle. As part of the CCSDS Encapsulation Service, Reed-Solomon Forward Error Correction (FEC) encoding is applied to the input data. For the Layer 2 return link, the T500SB provides frame synchronization, derandomization, Reed-Solomon FEC and Ethernet data distribution via Gigabit Ethernet. Similar to the Layer 2 process, the Layer 3 process supports standard routing protocols to provide ground to space routing using standard CCSDS Encapsulation and AOS Framing.
APPLICATION
 Demand for simplified interfaces between terrestrial and space systems is a growing industry trend. As newer space systems adopt TCP/IP over Ethernet for the forward/return links in lieu of complex, specialized serial interfaces, a more flexible ground station architecture is required.

The T500SB is a modular, tailorable, one-box solution that provides a standards-based network interface to the terrestrial networks and high speed serial interface (ECL, LVDS, TTL, RS-422) to a COTS Receiver such as the RT Logic T400/T1200HDR or other third party commercial modem. Software-defined algorithms enable a single T500SB to support multiple missions.

THE T500SB
DIFFERENCE


MODULAR DESIGN
 The T500SB is a high-performance, real-time, high-rate digital processing system with dynamically reconfigurable algorithms. The T500SB has a full range of firmware and software personality options for processing high-rate CCSDS/TDM telemetry, derandomization, error detection and correction (BER, Reed-Solomon, LDPC, CRC), OSI Layer 2 Bridge Functions and OSI Layer 3 Routing Functions.

The T500SB is a highly available server-class PC running a COTS Enterprise Linux OS with hot-swappable disk drives, dual hot-swappable power supplies, Intel Xeon CPU, multiple Gb Ethernet ports, RT Logic digital processor cards, and ready support for today’s computer peripherals (DVD, additional NICs, 10-Gigabit Ethernet, RAID, tape drives, iSCSI, etc.). It is available in 1U, 2U, 4U, or 5U configurations and mounts in a 19-inch rack. Multiple I/O options are available, including TTL, RS-422, D-ECL, LVPECL, and LVDS signal lines. Software/firmware-defined algorithms provide easy tailoring of a standard T500SB configuration to meet customer-specific requirements.
