Flexible Serial Data Extensions over Packet Switch Networks

IP•Tube V35 Standard Features

Dual LAN Interfaces
All IP•Tube V35 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

Assured Delivery Protocol

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 V35 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.

TheIP•Tube V35, 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 V35'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 250 kilobits per second. Latency minimization is accomplished with multidimensional adaptive clock configurations.

The IP•Tube V35 provides a transparent bandwidth regulated IP Tunnel for interconnecting remote Networks. With the IP•Tube V35 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 V35 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 V35 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 V35 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 V35 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 V35 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 V35's second 10/100BaseT Ethernet interface provides a management port when interconnecting the IP•Tube V35 through a Virtual Private Network. Each LAN interface of the IP•Tube V35 features independent IP network configurations.  

IP•Tube V.35 Optional Features

The IP•Tube V35 facilitates the transport of bulk data across a combination of IP and TDM WAN infrastructures. The IP•Tube V35 are deployed flexibly to support internetworking across varied LAN/WAN/MAN networks.
