IP•Tube RS530 SER

The IP•Tube RS530 SER, 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 SER encapsulates synchronous serial data from Data Terminal or Communication Equipment into IP packets. These IP packets are sent to a remote IP•Tube RS530 SER 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.

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 Kilobits to 2.048 Megabits per second. Latency minimization is accomplished with multidimensional adaptive clock configurations. A configured number of incoming packets are buffered in order to compensate for the packet delivery jitter introduced by the network. The size of this buffer needs to accommodate the peak amount of jitter.

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 latency introduced is dependent upon the clocking 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 security provisioning, such as firewalling, is maintained.

All IP•Tube SER RS530 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 Asymmetrical bandwidth links 
• Alternator Option for load balanced SDSL interconnects 
• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria

In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless or Broadband over Power Line, the IP•Tube SER RS530 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.

The IP•Tube SER RS530, 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 SER RS530'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 Megabits per second. Latency minimization is accomplished with multidimensional adaptive clock configurations.

The IP•Tube SER RS530 provides a transparent bandwidth regulated IP Tunnel for interconnecting remote Networks. With the IP•Tube SER RS530 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 SER RS530 IP Tunnel can also be utilized as a secondary path for fault tolerant mission critical applications.

In order to assure that circuits are extended over connections with fault tolerance the IP•Tube SER RS530 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 SER RS530 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 SER RS530 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 SER RS530 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 SER RS530's second 10/100BaseT Ethernet interface provides a management port when interconnecting the IP•Tube SER RS530 through a Virtual Private Network. Each LAN interface of the IP•Tube SER RS530 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.
