Overview & Applications

The Black•Tube CEP RS530 converts RS530 serial data connections into AES encrypted IP packets that extend the circuit overThe Black•Tube CEP RS530 converts RS530 serial data connections into AES encrypted IP packets that extend the circuit oververy cost effective Ethernet based LAN/WAN/MAN wired and wireless networks. The Black•Tube CEP RS530 encapsulatesAsynchronous, Synchronous and HDLC serial data into IP packets. The Black•Tube CEP RS530, which is available with oneto four RS530 interfaces software configurable as DCE or DTE, facilitates the interconnection of Serial Data Over IP betweenSerial Bulk Encryptors (KG-84/KIV7/OMNI), Data Terminals, Data Acquisition Systems, WAN Routers and Bridges....

Layer 1 
In Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be setIn Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be setwith data rates from 75 bits to 2.048 Megabits per second. Latency minimization is accomplished with FIFO sizing for the lowdata rate settings. A configured number of incoming packets are buffered in order to compensate for the packet delivery jitterintroduced by the Ethernet network. The size of this buffer is configured to accommodate the peak amount of jitter.

Asynchronous Over IP
Asynchronous characters from the RS530 interface with 5 to 8 data bits, baud rates from 1.2 to 38.4 kilobits, 1 or 2 stop bitsAsynchronous characters from the RS530 interface with 5 to 8 data bits, baud rates from 1.2 to 38.4 kilobits, 1 or 2 stop bitsthat are with or without parity are efficiently encapsulated into IP packets. The encapsulation supports block mode transfersto minimize the bandwidth required. Additionally the latency is controlled by setting the Tube Bytes per packet.

HDLC Over IP 
In Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame RelayIn Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame Relayor proprietary Data Links, are transported within IP packets as HDLC over IP. The latency introduced is dependent upon theclocking rate and the HDLC frame size. Minimum latency is obtained by maximizing the clock rate and minimizing the MTU.HDLC Over IP frames are directly sent out the Serial interface since Clock synchronization is not required. WAN securityprovisioning, such as firewalling, is maintained.

Black•Tube CEP RS530 Applications

Flexible Synchronous Serial Data Extension Over IP
The Black•Tube CEP RS530, whose serial interfaces are configurable as DCE or DTE, facilitates the transport of bulk dataacross a combination of IP and WAN infrastructures. The Black•Tube CEP RS530's flexibility supports internetworking acrossvaried LAN/WAN/MAN/Satellite networks. The size and frequency of the IP packets can be set with data bit rates from 76bits per second to 16 million bits per second. Latency minimization is accomplished with multidimensional adaptive clockconfigurations.

Defense and other Government agencies and Contractors face an ever-increasing need to establish Type 1 secure data communications links. These organizations often have access to flexible IP services such as Intranets, LANs, Metropolitan-Area Networks, WANs, or Wireless Ethernet. The Engage Black•Tube CEP RS530 allows users to leverage existing Bulk Data Encryption Modules for use over IP/Ethernet connections. Encrypted Data over IP with the Black•Tube CEP RS530 is a veryeconomical solution that leverages a proven installed base.

Encrypted Bulk Data-over-IP utilizing the Black•Tube CEP RS530 is an economical "Purpose Built" proven solution that leverages aninstalled base of high-performance INFOSEC devices. Approved Data Encryptors include:

The Black•Tube CEP installations achieve NERC CIP compliance with a combination of internal and external functions.

Internally the Management Module software has the sophistication to implement comprehensive policies and privileges for administrator and user accounts. Administrator policy includes removal, disabling or renaming.

Interoperability with external functions such as Syslog, Network Timing Protocol, TACACS+ and Radius with its support for RSA SecureID delivers trusted compliance.
