V.35 Over IP

Overview

Flexible Serial Data Extensions over Packet Switch Networks

The IP•Tube V35 converts V35 data connections, which employ leased circuits, into IP packets that extend the circuit over very cost effective Ethernet based LAN/WAN/MAN wired and wireless networks. The IP•Tube V35 encapsulates Synchronous or HDLC/SDLC serial data into IP packets and is available with one V35 interfaces ordered as a DCE or DTE. IP•Tube V35 facilitates the interconnection of Serial Data Over IP between Data Terminals, Data Acquisition Systems, WAN Routers and Bridges....
Layer 1
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.
 
HDLC Over IP
In Layer 2 operating mode HDLC Data frames clocked at 2.4 to 250 Kilobits, 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.
 
IP•Tubes with HDLCoIP connect to the V.35 leased line interface of an Enterprise's WAN Router and encapsulate the HDLC frames into an IP Packet that is sent to the remote site IPTube where it is presented to the remote WAN router as the original HDLC frame. Enterprises are able to connect to broadband IP services through their existing proven WAN infrastructure. Internal Ethernet networks remain isolated and security services such as Firewalling are maintained.

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.

 

 Flexible Synchronous Serial Data Extension Over IP

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.

 

 WAN Data Over IP

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.

 

 Assured Delivery Protocol

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.

 

 Service Quality Packet Prioritizing

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

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.

 

 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 opposite ADSL links
• Protector Option for Redundant Packet Path connections with Constant or Switch Over  Criteria

 

 VPN Network Management

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

 Protector Option
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 V35 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.
