IP•Tube RS530 DL

The IP•Tube RS530 DL whose synchronous serial interfaces are configurable as DCE or DTE, provides for the leveraging of existing synchronous serial bulk rate encryptors such as; KIV-7, KIV-7M, KIV-19, OMNI, and KG-84. The IP•Tube RS530 DL encapsulates synchronous serial data from Data Terminal or Communication Equipment into IP packets. These IP packets are sent to a remote IP•Tube RS530 DL where the serial data is de-encapsulated and synchronously clocked into the remote Data Equipment. The IP connection provides for the transparent interconnection of Synchronous Serial Data Equipment via LANs, WANs, MANs, Satellite and Wireless Ethernet. Configured Data rates from 2.4 Kilobits per second to 2.048 Megabits per second.

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 IP•Tube RS530DL allows users to leverage existing Bulk Data Encryption Modules for use over IP/Ethernet connections. Encrypted Data over IP with the IP•Tube RS530DL is a very economical solution that leverages a proven installed base.
Encrypted Bulk Data-over-IP utilizing the IP•Tube RS530DL is an economical "Purpose Built" proven solution that leverages an installed base of high-performance INFOSEC devices. Approved Data Encryptors for use with the IP•Tube RS530DL include:

• KIV-7
• KIV-7M
• KIV-19
• OMNI
• KG-84

The IP•Tube RS530DL, whose synchronous serial interface is configurable as DCE or a DTE, facilitates the transport of bulk data across a combination of IP and WAN infrastructures. The IP•Tube RS530DL's flexibility supports internetworking across varied LAN/WAN/MAN/Satellite networks. The size and frequency of the IP packets can be set with data bit rates from 2.4 Kilobits per second to 2.048 million bits per second. Latency minimization is accomplished with multidimensional adaptive clock configurations.Typical Applications 

• Secure LAN to LAN interconnect
• Secure Video TeleConferencing
• Field Command Centers
• Secure Wireless Bridge connections
• SIPRNet or NIPRNet access

The IP•Tube RS530DL provides a transparent bandwidth regulated IP Tunnel for interconnecting remote Networks. With the IP•Tube RS530DL WAN security provisioning, such as firewalling, is maintained. 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 RS530DL IP Tunnel can also be utilized as a secondary path for fault tolerant mission critical applications.

The IP•Tube RS530DL units are used to interconnect Synchronous Serial Data connections across Ethernet. Since Ethernet does not provide a common clock, an application appropriate method needs to be used to ensure that the clocking of the data out of one DTE and into the other DTE is not overrun or underrun. Additionally latency and overhead for the connection of data networks needs to be taken into account.The Engage IP•Tube RS530DL-DCE provides the clocking to their attached Data Terminal Equipment - DTEs. SCTCLOCK is used to clock Send Data from the DTE into IP packets that are sent to the interface S1’s TUBE ADDRESS. SCRCLOCK is used to clock the IP payload packet data from the buffer memory into the DTE. The IP•Tube RS530DL-DCE has a sophisticated adaptive clocking circuitry that supports the smooth synchronous clocking required by Video Codecs and configurations that minimize latency and overhead.

In order to assure that circuits are extended over connections with fault tolerance the IP•Tube RS530DL 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.

The IP•Tube RS530DL uses the Type of Service byte in the IP packets to prioritize the encapsulated data. The setting of the TOS byte can be used to ensure that the data from the IP•Tube RS530DL is ensured high priority.

Management of the IP•Tube RS530DL is accomplished with a Command Line Interface that is accessed through a Console or Telnet connection. Templates of the most common configuration provide for an Edit and Paste configuration. SNMP MIB I and II support is a standard feature.

All IP•Tube RS530DL 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
  
• The LAN ports can be configured to support connections over 2 opposite ADSL links
  
• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria

The IP•Tube RS530DL's second 10/100BaseT Ethernet interface provides a management port when interconnecting the IP•Tube RS530DL through a Virtual Private Network. Each LAN interface of the IP•Tube RS530DL features independent IP network configurations. 

The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated Synchronous Serial data. The extension of the RS530 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.
