Converts RS530 serial data connections into AES encrypted IP packets

Flexible Serial Data Extensions over Packet Switch Networks

 

Overview

The BlackTube CEP RS530 converts RS530 serial data connections into AES encrypted IP packets that extend the circuit overThe BlackTube 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 BlackTube CEP RS530 encapsulatesAsynchronous, Synchronous and HDLC serial data into IP packets. The BlackTube 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.

Assured Delivery Protocol
In order to assure high quality communications over linkswith intermittent or noisy performance, such as Wireless, the BlackTube CEP RS530 employs Engage’s robust AssuredDelivery Protocol with the following benefits:

Packet out of sequence detection and re-sequencing
• Duplicate skipping
• Lost packet retransmissions with configured delay
 
 

Three LAN Interfaces

All BlackTube CEP RS530 models ship with three10/100BaseT Ethernet LAN ports. The Ethernet interfaces provide for:

Management interface on MLAN
The Dual LAN Data Plane ports can be configured for:


- Connections over 2 Asymmetrical bandwidth links
- Protector Option for Redundant Packet Paths with Constant or Switch Over Criteria
