RPTF Overview Flashcards
What does RPTF stand for?
Replacement Patch and Test Facility
What does the RPTF do?
Provide manual patching, encryption, and testing for DCSS and RMCE
What does DCSS stand for?
Digital Communications Subsystem
What does RMCE stand for?
Red and Black Monitoring and Control Equipment
What does WSOMS stand for?
Wideband Satellite Operational Management Systems
How many racks does the RPTF consist of?
5 altogether
3 Red and 2 Black
Racks consist of:
Patch Panels (Red=Plain text Black=cypher text)
Test Panels (Breakout Test Panel and Oscilloscope Interface Panel)
Encryption Devices (KIV-7M and KG 175D)
Signal Conversion (CSU/DSU)
Electrical/Optical Conversion (Fiber)
Equipment Management
Multiplexing (MSPP and PCU/2)
What does the Monitor Panel/Oscilloscope do?
Provides a means of taking high impedance signal sample from individual data circuits.
Allows for monitoring of TX/RX Data, TX/RX Timing, Terminal Timing, and External Timing.
What does the Breakout Test Panel do?
The breakout panel is used in conjunction with the Oscilloscope to aid in diagnosis of problems with the DECS, GTC3S, or WSOMSNet circuits. The panel breaks out the circuit signals for ease of probing with TMDE.
What does SAASM stand for, and what does it do?
Selective Availability Anti-Spoofing Module
Provides precise Network Time Protocol (NTP) Services
What do the Black/Red Patch Panels do?
The Black/Red Patch Panels provide physical, hard-contact access to any data circuit, and through the use of patch cord, the operator can directly monitor a circuit, split the data circuit and test the circuit toward the DTE, or test the circuit toward the DCE.
What does the Crypto Housing do?
The Crypto Housing provides the mounting interface, and power for the KIV-7M
The modified Crypto Housing provides the mounting, interface, and power for the KIV-7M and DS3 module.
What does the DS3 module do?
The DS3 module provides KG-95 emulation capability using a KIV-7M Encryptor
What does the Ethernet Switch do?
Red rack switch separates physical links from logical groupings of endpoints by linking multiple KIV-7M human control interfaces into a single computer
Black rack switch interfaces with the CSU/DSUs and the MSPPs
What does the Fiber Optic Patch Panel do?
The Fiber Optic Patch Panel provides a connection for fiber cables connected to the Black Network Racks.
What does the Fiber Distribution Patch Panel do? (Single and Multi Mode)
Single Mode- Provides a connection for single mode fiber connected to the Black Rack for the PCU/2’s
Multi Mode- Provides a connection for multi-mode fiber connected to the Black Rack for the MSPP
What does the Fiber Optic Media Converter do?
Converts between Ethernet and Fiber Optic.
Red Rack- Rack 4 contains a media converter which connects the SAASM NTP signal to the WSOMSNet router
Black Rack- Rack 10 contains a media converter which connects the SAASM NTP signal to the Black RMCE network
What does PCU/2 stand for and what does it do?
Port Concentrator Unit Cable Extension
Provides interfaces to extend GTC3S circuits up to two kilometers over single mode fiber
Multiplexes and converts the incoming 16 RS-232 inputs onto a single mode fiber output
What does MSPP stand for and what does it do?
Multiservice Provisioning Platform
The MSPP aggregates data, voice, and video services for transport
Provides efficient data switching and cross connect functions for: 10/100/100-Mbps Ethernet interfaces and 2-Mbps to 2.5-Gbps Time Division Multiplexing (TDM) traffic in optical networks
What does the Customer Interface Patch Panel do?
The Customer Interface Patch Panel provides a communication path for the T1 circuits with the ability to monitor and reroute them with the patching capability.
What does the Channel Service Unit/ Data Service Unit (CSU/DSU) do?
Converts a parallel T1 signal into a serial T1 signal and vice versa
Provides selectable data rates from 56 Kbps to 1536 Kbps
*Various loopbacks and Bit Error Rate Test (BERT) are built into the CSU/DSU
What is GT3CS circuit signal flow?
Red side P/P > KIV-7m > Black side P/P > WSOC PCU/2 > Fiber Interface > TCF PCU/2 > Network
What is the T1 circuit signal flow?
Red side P/P > KIV-7M > Black side P/P > CSU/DSU >T1 P/P > MSPP > TCF Peer Device > Network
What is the DS3 circuit signal flow?
Red side P/P > KIV 7M w/ DS3 Module > Black side P/P > MSPP > TCF Peer Device > Network
