Flexible Serial Data Extensions over IP Packet or MPLS Networks
Overview
The Black•Tube CEP DDS converts DDS serial data connections into AES encrypted IP packets, extending the serial data over very cost effective Ethernet or MPLS based LAN/WAN/MAN wired and wireless networks. Synchronous, Asynchronous, Isochronous or HDLC serial data is encrypted then encapsulated into IP packets. This facilitates the interconnection of Serial Data over IP between Serial Bulk Encryptors (KIV7/OMNI), Data Terminals, Data Acquisition Systems, WAN Routers and Bridges and SCADA RTUs
Layer 1 with Isochronous Support
In Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be set with data bit rates from 2.4 to 64 kilobits per second. Isochronous serial protocols, such as Conitel, are transported synchronously to maintain message alignment. A configured number of incoming packets are buffered in order to compensate for the packet delivery jitter introduced by the network. The size of the Tube bit buffer is configurable to accommodate the peak amount of jitter.
Asynchronous Over IP
Asynchronous characters from the DDS interface with 5 to 8 data bits, baud rates from 1.2 to 38.4 kilobits, 1 or 2 stop bits that are with or without parity are efficiently encapsulated into IP packets. The encapsulation supports block mode transfers to minimize the bandwidth required. Additionally the latency is controlled by setting the Tube Bytes per packet.
SDLC Over IP
In Layer 2 operating mode SDLC Data frames, such as those used by IBM 317x Controllers, Wide Area Networking protocols PPP and Frame Relay or proprietary Data Links, are transported within IP packets as SDLC over IP. The Serial to Packet conversion only occurs when SDLC frames are active.
SCADA Protocol Transparency
The Black•Tube CEP transports Bit or Byte orientated SCADA protocols transparently because of its unique TDM circuit emulation capability. RTU transmit data is encapsulated into IP packets at configurable samples per second and deencapsulated at the far end at the same rate, ensuring properly timed RTU SCADA data delivery.
Assured Delivery Protocol
| Protector OPTION -PRO The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated DDS data. The extension of the DDS has a fault tolerant link that is configured to always on, or with switch over criteria. |
