TELEMETRIX 501 (T501)
|
OVERVIEW
|
The RT Logic Telemetrix® 501 (T501) offers an innovative, full-function, high-availability architecture
for satellite control center front ends. The T501 incorporates advanced technology to package up to four modular front-ends (slices) in a single
rack-mount chassis. Each hot-swappable T501 slice supports four streams and connects via a plug-and-play USB interface. The T501 host chassis
contains two redundant, hot-swappable power supplies and a hot-swappable fan assembly to offer high availability for mission critical operations.

APPLICATION
|
The T501 slice connects to a rack-mount, server-class PC that hosts the data transfer and device control software
for each T501. This server PC can be standalone or shared with the telemetry/command server used by the satellite TT&C software. The T501 software
interface is backwards compatible with our Telemetrix 505 (T505), protecting the customer’s software investment. A Java-based interface supports
configuration and status of the T501 chassis and T501 slices.
Telemetry process functions include format conversion, frame synchronization, and IRIG/NTP time-tagging. The T501 can be configured to support TDM
or CCSDS processing, including Reed-Solomon decoding and VCDU/packet processing. The T501 can also be used to generate simulated telemetry streams
for loopback testing. Data recording/replay are supported via the host server PC.
Command processing functions include conversion to an uplink encryptor’s ternary format, fill command generation, and command echo checking. COP-1
telecommand processing is supported.
The T501 is designed for compatibility with the traffic interfaces for all commonly used encryption/decryption equipment including KG61/62s (Elwell),
Mykotronx units, and the KI-17. The T501 device control software provides a common, network-based means for monitoring and control of KG equipment.

PLUG-AND-PLAY
|
Each T501 slice is configurable via XML files that download the module’s personality. T501 slices are completely
interchangeable, requiring minimal spares to support the full satellite control center.
|
REDUCED SIZE/ COMPLEXITY
|
Each T501 slice supports four telemetry/command streams in a modular, small footprint (1.6-inch x 5-inch x 9-inch).
A rack-mount host chassis (3U (5.25-inch) tall) supports up to four T501s.
The T501 has no internal cabling for data and control/status signals. Internal backplanes provide convenient breakout of the RS-422 telemetry/command
(HD-26s), IRIG (BNCs), and USB connections at the rear of the chassis.
|
HIGH AVAILABILITY
|
Each T501 slice is hot-swappable. Replacement and reconfiguration of a failed slice requires fewer than 90 seconds.
The host chassis has redundant, hot-swappable power supplies for continuous operations. The fan assembly is also hot-swappable.
