IP•Tube SER RS232

The IP•Tube SER RS232 converts RS232 serial data connections into 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 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, 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 75 bits to 256 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 RS232 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.

HDLC Over IP
In Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame Relay or proprietary Data Links, are transported within IP packets as HDLC over IP. The Serial to Packet conversion only occurs when HDLC frames are active.

Dual LAN Interfaces
All IP•Tube SER RS232 models ship with dual 10/100BaseT Ethernet LAN ports.

The dual Ethernet interfaces provide for:
• Management interface on LAN port 2 when LAN port 1 is connected to a VPN tunnel
• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria

Assured Delivery Protocol
In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless, the IP•Tube SER RS232 employs Engage’s robust Assured Delivery Protocol with the following benefits:

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

WAN Data Over IP

Assured Delivery Protocol

In order to assure that circuits are extended over connections with fault tolerance the IP•Tube SER RS232 has as a standard capability an Assured Delivery Protocol that supports high performance full duplex real time data. The protocol has packet out of sequence detection and re sequencing, duplicate skipping, and real time lost packet retransmission with configured delay.

IP•Tube SER RS232for Serial Data Over IP/Ethernet Connections 

The "Purpose Built" Engage IP•Tube SER RS232 encapsulates synchronous or HDLC serial data from Data Terminal or Data Communication Equipment such as Bulk Encryptors (KIV7/OMNI), Terminal Servers, Modems, Video Codecs, WAN Routers into IP packets. The IP connection provides for the transparent interconnection of Data Terminal/Communication Equipment via LANs, WANs, MANs, Satellite and Wireless Ethernet. The size and frequency of the IP packets can be set to bit rates from 2.4 Kilobits per second to 250 Kilobits per second with N times 2.4K, 56K and 64K clocking.

The IP•Tube SER RS232 facilitates the transport of bulk data across a combination of IP and TDM WAN infrastructures. The IP•Tube SER RS232 are deployed flexibly to support internetworking across varied LAN/WAN/MAN networks.

WAN Data Over IP

IP•Tube SER RS232 provides a transparent bandwidth regulated IP Tunnel for interconnecting remote Networks. WAN Protocols, such as PPP and Frame Relay, that utilize HDLC framing are encapsulated with HDLC Over IP. Broadband Service providers are able to transport Enterprise Wide Area Network connections with inband management of the Committed Information Rates. The IP•Tube SER RS232's IP Tunnel can also be utilized as a secondary path for fault tolerant mission critical applications.
