The CR-6200 series contains ruggedized managed gigabit and 10gigabit Ethernet switches with router support specially designed to operate reliably in harsh climatically and noisy electrical demanding environments (e.g. high altitude, extreme shock, and vibration, wide temperatures, humidity, dust and water exposure, noisy EMI, dirty power) of military applications.
The switches/routers enable modularity and provide growth while delivering optimal performance for Size, Weight, Power, and Cost (SWaP-C) constrained aircraft applications onboard helicopters and fixed-wing aircraft.
The units are designed to meet the environmental requirements of MIL-STD 810 and the EMI/EMC
requirements (Conducted and Radiated Emissions and Susceptibility) of MIL-STD 461 and -704.
This fully managed, Layer 2/3 gigabit/10gigabit switch/router family provides a powerful set of networking features, including support for IPv4 multicast traffic filtering according to static filters or IGMP snooping,
Virtual Local Area Networks (VLANs), port control (speed / mode / statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), SNMP v1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), port mirroring and network redundancy based on RSTP/MSTP.
The router implementation is based on a separate router board with an Intel Atom processor and is capable of routing near 1Gbps wire speed. The router board has spare capacity on memory, flash, and CPU for installing and running third-party software on the same board while ensuring separation from the router. A wide range of router protocols are supported including multicast routing. The router implementation can be equipped with the OnTime Networks router and firewall package providing routing speeds up to 800Mbps, the Cisco’s 5921 Embedded Services Router (ESR) Advanced Enterprise router package, providing up to 500Mbps of routing speed, or ATCorp's Routing and Encryption Suite (ARES) router, CRR-1000-5, a router and VPN gateway device in conformance with several US and NATO
cyber security certification standards.
The CR-6200 series can be equipped with a reliable and accurate PTP Grand Master Clock (GMC) or
Transparent Clock/Slave Clock (TC/SC) according to IEEE1588 Std 2008. The platform also supports PTP translation to/from PTPv1 (IEEE1588 Std 2002) from/to PTPv2 (IEEE1588 Std 2008). NTP server or client operation can also be supported.
The platform can be equipped with a high-end OCXO for extreme clock hold-over capability in case the time base source is lost. This means minimum clock drift even in an environment with large temperature variations. A Li battery can be used to keep track of the time of day when the unit is not powered. The lifetime of the battery is more than 10 years.
HSR is an alternative network redundancy protocol for Ethernet that provides seamless failover against failure of a network component. HSR nodes have 2 gigabit ports and act as a switch (bridge), which allows arranging them into a ring structure, without dedicated switches. HSR is suited for applications that request high availability and no switchover time, where the recovery time of commonly used protocols such as the Rapid Spanning Tree Protocol (RSTP) is too long. OnTime Networks switches with HSR provides hardware support (FPGA) to forward or discard frames within microseconds. HSR network nodes have at least two gigabit Ethernet ports, each attached to a neighboring HSR node so that always two paths exist between two HSR nodes.
